The Design of New Catalysts for Biomass Conversion with Atomic Layer Deposition

Meeting Program — April 2015

Depart­ment of Chem­i­cal and Bio­log­i­cal Engi­neer­ing
Uni­ver­si­ty of Wis­con­sin, Madi­son, WI

Abstract
The objec­tive of the Huber research group is to devel­op new cat­alyt­ic process­es and cat­alyt­ic mate­ri­als for the pro­duc­tion of renew­able fuels and chem­i­cals from bio­mass, solar ener­gy, and nat­ur­al gas resources. We use a wide range of mod­ern chem­i­cal engi­neer­ing tools to design and opti­mize these clean tech­nolo­gies includ­ing: het­ero­ge­neous catal­y­sis, kinet­ic mod­el­ing, reac­tion engi­neer­ing, spec­troscopy, ana­lyt­i­cal chem­istry, nan­otech­nol­o­gy, cat­a­lyst syn­the­sis, con­cep­tu­al process design, and the­o­ret­i­cal chem­istry. In this pre­sen­ta­tion we will first dis­cuss the hydrodeoxy­gena­tion of bio­mass into dif­fer­ent fuels and chem­i­cals. In addi­tion we can use HDO to eas­i­ly pro­duce new class­es mol­e­cules that are not cur­rent­ly pro­duced from petro­le­um feed­stocks. Hydrodeoxy­gena­tion (HDO) is a plat­form tech­nol­o­gy used to con­vert liq­uid bio­mass feed­stocks (includ­ing aque­ous car­bo­hy­drates, pyrol­y­sis oils, and aque­ous enzy­mat­ic prod­ucts) into alka­nes, alco­hols and poly­ols. In this process the bio­mass feed reacts with hydro­gen to pro­duce water and a deoxy­genat­ed prod­uct using a bifunc­tion­al cat­a­lyst that con­tains both met­al and acid sites. The chal­lenge with HDO is to selec­tive­ly pro­duce tar­get­ed prod­ucts that can be used as fuel blend­stocks or chem­i­cals and to decrease the hydro­gen con­sump­tion. We will dis­cuss how dif­fer­ent bio­mass based feed­stocks can be con­vert­ed into fuels or chem­i­cals by HDO. We will out­line the fun­da­men­tal cat­alyt­ic chem­istry and the sci­en­tif­ic chal­lenges. We will then dis­cuss how ALD can be used to design improved cat­alyt­ic mate­ri­als.

Atom­ic lay­er depo­si­tion (ALD) has emerged as a tool for the atom­i­cal­ly pre­cise design and syn­the­sis of cat­alyt­ic mate­ri­als. We dis­cuss exam­ples where the atom­ic pre­ci­sion has been used to elu­ci­date reac­tion mech­a­nisms and cat­a­lyst struc­ture-prop­er­ty rela­tion­ships by cre­at­ing mate­ri­als with a con­trolled dis­tri­b­u­tion of size, com­po­si­tion, and active site. We high­light ways ALD has been uti­lized to design cat­a­lysts with improved activ­i­ty, selec­tiv­i­ty, and sta­bil­i­ty under a vari­ety of con­di­tions (e.g., high tem­per­a­ture, gas- and liq­uid-phase, and cor­ro­sive envi­ron­ments). In addi­tion, due to the flex­i­bil­i­ty and con­trol of struc­ture and com­po­si­tion, ALD can cre­ate myr­i­ad cat­alyt­ic struc­tures (e.g., high sur­face area oxides, met­al nanopar­ti­cles, bimetal­lic nanopar­ti­cles, bifunc­tion­al cat­a­lysts, con­trolled micro-envi­ron­ments, etc.) that con­se­quent­ly pos­sess applic­a­bil­i­ty for a wide-rang­ing num­ber of chem­i­cal reac­tions (e.g., CO2 con­ver­sion, elec­tro­catal­y­sis, pho­to­cat­alyt­ic and ther­mal water split­ting, methane con­ver­sion, ethane and propane dehy­dro­gena­tion, and bio­mass con­ver­sion). Final­ly, the out­look for ALD-derived cat­alyt­ic mate­ri­als is dis­cussed with empha­sis on the pend­ing chal­lenges as well as areas of sig­nif­i­cant poten­tial for build­ing sci­en­tif­ic insight and achiev­ing prac­ti­cal impacts.

Abstract
In sup­port­ed met­al cat­a­lysts, the trade­off between activ­i­ty and selec­tiv­i­ty presents an impor­tant chal­lenge for cat­a­lyst design. By allow­ing two dis­sim­i­lar met­als, we can attempt to tune the selec­tiv­i­ty of the cat­a­lyst by enhanc­ing bond-for­ma­tion and des­orp­tion rates through the addi­tion of a less-reac­tive ele­ment, while main­tain high bond dis­so­ci­a­tion activ­i­ty from the more active met­al. The result­ing cat­a­lyst prop­er­ties depend strong­ly on the cat­a­lyst com­po­si­tion and ratio of the two met­als (elec­tron­ic effect), but may also depend on the local struc­ture of sur­face ensem­bles of the alloy com­po­nents (geo­met­ric effect). In this talk we will explore two exam­ples of bina­ry alloys where sur­face com­po­si­tion and geom­e­try play an impor­tant role in deter­min­ing the selec­tiv­i­ty of the cat­a­lyst through den­si­ty func­tion­al the­o­ry (DFT).

In the first exam­ple, we have exam­ined the effect of plat­inum tin alloy struc­ture and com­po­si­tion on the kinet­ics and ther­mo­dy­nam­ics of dehy­dro­gena­tion and coke for­ma­tion path­ways dur­ing light alka­ne dehy­dro­gena­tion. Light alka­ne dehy­dro­gena­tion to olefins can add sig­nif­i­cant val­ue to hydro­car­bon process­es that gen­er­ate ethane and propane by con­vert­ing low val­ue com­mod­i­ty fuels to high-val­ue chem­i­cal and poly­mer pre­cur­sors. Sup­port­ed Pt cat­a­lysts are known to be active but show sig­nif­i­cant coke for­ma­tion and deac­ti­va­tion, which can be alle­vi­at­ed by alloy­ing with Sn and oth­er main group ele­ments. We aim to under­stand how the struc­ture and com­po­si­tion of these alloys affect their abil­i­ty to sup­press coke for­ma­tion. We inves­ti­gate the poten­tial ener­gy sur­faces from ethane along the desired path­way to ethene, and along the unde­sired path­ways towards sur­face carbon/coke. The effect of Pt/Sn ratio and sur­face geom­e­try is inves­ti­gat­ed. As com­pared to pure Pt, bond scis­sion is more dif­fi­cult on the alloys and des­orp­tion is more facile, and both effects are enhanced as three-fold hol­low sites con­sist­ing of only Pt atoms are elim­i­nat­ed.

In the sec­ond exam­ple, we eval­u­ate Au/Ni near-sur­face alloys as poten­tial oxy­gen reduc­tion cat­a­lysts for the direct syn­the­sis of hydro­gen per­ox­ide from O2 and H2, there­by avoid­ing the cur­rent anthraquinone process. While Au may have high­er O-H bond for­ma­tion activ­i­ty, it is a poor O2-dis­so­ci­a­tion cat­a­lyst, and like­wise Ni is very effec­tive at O2-dis­so­ci­a­tion but not oxy­gen hydro­gena­tion. Alloy­ing Au with Ni(111) low­ers H2 dis­so­ci­a­tion bar­ri­er while keep­ing the O2 dis­so­ci­a­tion bar­ri­er large rel­a­tive to O2 hydro­gena­tion. Des­orp­tion of H2O2 is sim­i­lar­ly com­pet­i­tive with H2O2 dis­so­ci­a­tion on alloy sur­faces. How­ev­er, the selec­tiv­i­ty for the OOH rad­i­cal remains a chal­lenge, with bar­ri­er­less O-O bond dis­so­ci­a­tion and large (1.3 eV) hydro­gena­tion bar­ri­ers. We fur­ther inves­ti­gate how the Au/Ni sur­face may rearrange itself to regen­er­ate three-fold hol­lows of Ni atoms in the pres­ence of strong­ly adsorb­ing sur­face species.

Abstract
Methan­otroph­ic bac­te­ria con­tain­ing par­tic­u­lar methane monooxy­ge­nase (pMMO), a Cu-con­tain­ing enzyme, or sol­u­ble methane monooxy­ge­nase (sMMO), an iron-met­al­loen­zyme can oxi­dize methane to methanol selec­tive­ly at ambi­ent con­di­tions 1. The zeo­lite Cu-ZSM-5 was report­ed to acti­vate the methane C-H bond—with a homolyt­ic bond dis­so­ci­a­tion ener­gy of 104 kcal/mol— at tem­per­a­tures as low as 120 °C 2 after pre­treat­ment in O2 3. The reac­tive cop­per species are believed to con­tain extra-lat­tice oxy­gen, and in the case of Cu-ZSM-5, to be a mono-μ-oxo-dicop­per com­plex ([Cu—O—Cu]2+) 4. Although a cor­re­la­tion was found between the con­cen­tra­tion of mono-μ-oxo-dicop­per species and the amount of methanol pro­duced by Cu-ZSM-5 5, no such cor­re­la­tion was found for oth­er zeo­lites that pro­duce methanol such as Cu-mor­den­ite and Cu-fer­rierite 2. We have recent­ly showed methanol pro­duc­tion on cop­per (II) exchanged small pore zeo­lites includ­ing SSZ-13 (CHA), SSZ-16 (AFX) and SSZ-39 (AEI) with yields as high as 39 μmol CH3OH/g and CH3OH/Cu ratios up to 0.09 (the largest report­ed to date).6 Here, cop­per species in these small pore zeo­lites were inves­ti­gat­ed with UV–vis and Raman spec­troscopy after O2-treat­ment at a tem­per­a­ture of 450 °C. No evi­dence of mono-μ-oxo-dicop­per species was found in the spec­tra of Cu-SSZ-13,Cu-SSZ-16 and Cu-SSZ-39 6, how­ev­er Cu—Oextralattice vibra­tions at 574 cm-1 were detect­ed in Raman spec­tra of Cu-SSZ-13 and Cu-SSZ-39 zeo­lites which is indica­tive of a dif­fer­ent Cux­Oy active species respon­si­ble for methanol pro­duc­tion in small pore zeo­lites.

Abstract
Cat­alyt­ic reac­tions that involve oxy­gen can be found in a large num­ber of process­es, includ­ing those in ener­gy-relat­ed appli­ca­tions, in emis­sion con­trol and in process­es impor­tant for the chem­i­cal indus­try. Whether the cat­alyt­ic reac­tion is an oxy­gen inser­tion step as in a selec­tive oxi­da­tion reac­tion, or an oxy­gen removal step as in a hydrodeoxy­gena­tion reac­tion, oxy­gen has proven to be a very chal­leng­ing com­po­nent, often deter­min­ing the selec­tiv­i­ty of the reac­tion. Some exam­ples from our lab­o­ra­to­ries that bridge catal­y­sis and elec­tro-catal­y­sis will be dis­cussed, rang­ing from oxida­tive dehy­dro­gena­tion of alka­nes to oxy­gen reduc­tion reac­tion in fuel cells.

Challenges and Advances in Catalytic Fast Pyrolysis of Biomass using Zeolites

Meeting Program — January 2015

Abstract
Ther­mo­chem­i­cal con­ver­sion of bio­mass to ener­gy, fuels and chem­i­cals is an attrac­tive tech­nol­o­gy for the tran­si­tion from fos­sil resources to a renew­able-based econ­o­my. Cat­alyt­ic Fast Pyrol­y­sis (CFP) of bio­mass is a par­tic­u­lar­ly inter­est­ing tech­nol­o­gy for bio­mass con­ver­sion con­sid­er­ing the already exten­sive infra­struc­ture for hydro­car­bons pro­duc­tion. How­ev­er, many chal­lenges remain unsolved before the deploy­ment of the bio­mass CFP can be real­ized, includ­ing: a) char and coke for­ma­tion, which caus­es rapid cat­a­lyst deac­ti­va­tion; and b) high oxy­gen con­tent in the bio-oil, which makes it incom­pat­i­ble with today’s hydro­car­bon fuels. With respect to the first chal­lenge, it is imper­a­tive to first under­stand the ori­gin and the for­ma­tion of char and coke dur­ing CFP. Con­sid­er­ing the sec­ond chal­lenge, it is impor­tant to under­stand which cat­a­lyst prop­er­ties can enhance the deoxy­gena­tion reac­tions and increase the bio-oil selec­tiv­i­ty to hydro­car­bons. ZSM-5 zeo­lites have been rec­og­nized as one of the most promis­ing zeo­lites for CFP due to their shape selec­tiv­i­ty and their deoxy­gena­tion abil­i­ty. How­ev­er, their micro­p­ore struc­ture can lim­it the acces­si­bil­i­ty of heavy com­pounds to the active sites of their frame­work. Mod­i­fy­ing the zeo­lite pore archi­tec­ture to cre­ate hier­ar­chi­cal struc­tures could pro­vide a solu­tion to this chal­lenge. Fur­ther­more, the CFP process design itself (in situ or ex situ) can alter the prod­uct yield and selec­tiv­i­ty and, thus, the bio-oil qual­i­ty. Dur­ing this pre­sen­ta­tion we will dis­cuss how the zeo­lite prop­er­ties and loca­tion with­in the CFP process (in situ or ex situ) can affect the coke/char for­ma­tion and the deoxy­gena­tion reac­tions for enhanced bio-oil qual­i­ty.

Iou­lia (Julia) Val­la is an Assis­tant Pro­fes­sor in the Chem­i­cal & Bio­mol­e­c­u­lar Engi­neer­ing Depart­ment at the Uni­ver­si­ty of Con­necti­cut. She received her PhD in the field of the devel­op­ment of new zeo­lites for the decom­po­si­tion of sul­fur com­pounds in naph­tha and the pro­duc­tion of envi­ron­men­tal gaso­line from the Aris­to­tle Uni­ver­si­ty of Thes­sa­loni­ki in Greece. She has served in a lead­er­ship role with Rive Tech­nol­o­gy, Inc. on the com­mer­cial­iza­tion of a nov­el zeo­lite with ordered meso­porous struc­ture for refin­ery appli­ca­tions. Dr. Valla’s research focus­es on the mod­i­fi­ca­tion of zeo­lites struc­ture and their appli­ca­tion in catal­y­sis, adsorp­tion and ener­gy. She is the author/­co-author of 9 papers in peer-reviewed jour­nals, 1 book chap­ter and 2 patents. Dr. Val­la is the recip­i­ent of the Euro­pean Award “RUCADI, Recov­ery and Uti­liza­tion of Car­bon Diox­ide” for her study on the role of CO2 on the reform­ing of nat­ur­al gas for the pro­duc­tion of methanol. At the Uni­ver­si­ty of Con­necti­cut, Dr. Val­la received an award spon­sored by the Nation­al Sci­ence Foun­da­tion for the study “Turn­ing Tars into Ener­gy: Zeo­lites with Hier­ar­chi­cal Pore Struc­ture for the Cat­alyt­ic Removal of Tars”. The study is focused on a nov­el appli­ca­tion of hier­ar­chi­cal­ly struc­tured meso­porous bifunc­tion­al cat­a­lysts for the ther­mo­chem­i­cal upgrad­ing of unde­sir­able tars from bio­mass pyrol­y­sis or gasi­fi­ca­tion to valu­able hydro­car­bons.
