In Memoriam: Theodore A. Koch (1925–2014)

Theodore-Koch-204x300

Dr. Theodore A. Koch, 88, a retired DuPont research sci­en­tist passed away peace­fully at his home in Wilm­ing­ton, Delaware on Sep­tem­ber 13, 2014.

A native of upstate New York, Koch stud­ied chem­istry at St. Michael’s Col­lege in Burling­ton, VT and the Uni­ver­sity of Penn­syl­va­nia in Philadel­phia, PA, earn­ing his Ph.D. in chem­istry in 1952. He joined the DuPont Co. ulti­mately retir­ing from its Nylon busi­ness unit as a DuPont Fel­low after 48 years of ser­vice. An author­ity on het­ero­ge­neous cat­a­lysts, Koch spent his entire career devel­op­ing chem­i­cal process­es and bring­ing them from the bench­top to com­mer­cial­iza­tion with marked cre­ativ­ity and tenac­i­ty.

Notable tech­ni­cal accom­plish­ments in Koch’s career includ­ed devel­op­ing a new cat­a­lyst for nitrous oxide destruc­tion (an ozone-deple­tion byprod­uct from Nylon man­u­fac­ture), devel­op­ment of a new process for hydro­gen cyanide man­u­fac­ture and improve­ments to many poly­mer inter­me­di­ates process­es. Koch received the award for Excel­lence in Cat­alytic Sci­ence and Tech­nol­ogy from the Catal­y­sis Club of Philadel­phia in 1994 and the Lavoisi­er Medal for Tech­ni­cal Excel­lence from the DuPont Co. in 1998. His exter­nal roles includ­ed adjunct Pro­fes­sor of Chem­i­cal Engi­neer­ing at the Uni­ver­sity of Delaware; pres­i­dent of the Catal­y­sis Club of Philadel­phia; and mem­ber­ship in the North Amer­i­can Catal­y­sis Soci­ety, the Amer­i­can Insti­tute of Chem­i­cal Engi­neers, the Organ­ic Reac­tions Catal­y­sis Soci­ety, and the Amer­i­can Chem­i­cal Soci­ety. He held 29 patents and co-authored 18 jour­nal arti­cles and one text­book on catal­y­sis enti­tled, “Cat­a­lyst Man­u­fac­ture.”

Koch is sur­vived by his wife of 62 years, Anne, his five chil­dren, five grand­chil­dren and extend­ed fam­ily. His mem­ory lives on through the Theodore A. Koch Fund that will rec­og­nize and reward Delaware Val­ley achieve­ments in catal­y­sis research. Char­i­ta­ble dona­tions may be made to the Catal­y­sis Club of Philadel­phia, Ted Koch Fund, c/o Stephen Har­ris, Trea­surer, Ren­matix, 660 Allen­dale Road, King of Prus­sia, PA 19406.

In an attempt to facil­i­tate reg­is­tra­tion process we plan to intro­duce cred­it card as an addi­tion­al method of pay­ment. Addi­tion­al details will be announced in one of the forth­com­ing meet­ings. Until then we strong­ly encour­age advance reser­va­tions for the meet­ings either using our online reg­is­tra­tion form in our web­page or by con­tact­ing our arrange­ments chair, Eyas Mah­moud (eyas@​udel.​edu), direct­ly. Dues for the 2014–15 sea­son will remain at $25.00 ($5.00 for the local club and $20.00 to the nation­al club). Dues for stu­dents, post­docs and retirees will be $10.00 ($5.00 for the local club and $5.00 to the nation­al club).

Our annu­al stu­dent poster com­pe­ti­tion (orga­nized by Bingjun Xu of Uni­ver­si­ty of Delaware) will again be held in Octo­ber. It pro­vides an impor­tant forum for local stu­dents to dis­sem­i­nate their work and inter­act with fel­low sci­en­tists from indus­try and acad­e­mia. Fur­ther­more, select­ed stu­dents from local uni­ver­si­ties will also be giv­en the oppor­tu­ni­ty to brief pre­sen­ta­tion of their work at cer­tain meet­ings.

Feel free to con­tact me or any oth­er offi­cers with any com­ments or con­cerns, and keep check­ing peri­od­i­cal­ly our web­site (www​.catal​y​sis​clubphilly​.org) and our LinkedIn account for news or updates.
I’m look­ing for­ward to see­ing all of you in Sep­tem­ber.

Challenges and Solutions in Developing Zeolite Supported Transition Metal Catalysts for Lean-Burn NOx Emission Control

Meeting Program — September 2014

Abstract — Reduc­tion of NOx emis­sions from lean-burn engine exhaust has been a main top­ic of envi­ron­men­tal catal­y­sis in the past 20 years. The chal­lenge is the selec­tive con­ver­sion of a low con­cen­tra­tion of NOx (~100 ppm) in the pres­ence of large excess of O2 (~10%). Although zeo­lite sup­port­ed tran­si­tion met­al cat­a­lysts were iden­ti­fied in ear­ly 1990s as promis­ing cat­a­lysts, such a tech­nol­o­gy was not imple­ment­ed till recent­ly.

Ear­ly stud­ies main­ly focused on the devel­op­ment of zeo­lite sup­port­ed tran­si­tion met­al, pri­mar­i­ly Cu and Fe, cat­a­lysts for the selec­tive cat­alyt­ic reduc­tion of NOx with hydro­car­bons (HC-SCR). Even though the HC-SCR tech­nol­o­gy has been con­sid­ered as the “holy grail” of auto­mo­tive catal­y­sis, tech­ni­cal chal­lenges on the activ­i­ty, selec­tive and dura­bil­i­ty of the cat­a­lysts were rec­og­nized to be dif­fi­cult to over­come for the tech­nol­o­gy to be imple­ment­ed into real world appli­ca­tions. How­ev­er, the vast amount of research work, espe­cial­ly the fun­da­men­tal stud­ies on the reac­tion and the cat­a­lyst deac­ti­va­tion mech­a­nisms, demon­strat­ed that the activ­i­ty and selec­tiv­i­ty of this type of cat­a­lysts can be dras­ti­cal­ly improved if an alter­na­tive reduc­tant, NH3, is avail­able in the feed.

Exten­sive inves­ti­ga­tions on the selec­tive cat­alyt­ic reduc­tion of NOx with NH3 (NH3-SCR) began in the mid­dle 2000s aimed to enable diesel pow­ered vehi­cles to meet the US EPA 2007/2010 emis­sion reg­u­la­tions. Both Cu and Fe cat­a­lysts were con­sid­ered. Zeo­lite sup­port­ed Cu SCR cat­a­lysts are more active at low tem­per­a­ture, thus more attrac­tive for appli­ca­tions with low exhaust tem­per­a­ture. The con­ven­tion­al medi­um-pore zeo­lite (10-ring, such as ZSM-5) or large-pore zeo­lite (12-ring, such as beta) sup­port­ed Cu cat­a­lysts, how­ev­er, can­not meet the long-term dura­bil­i­ty require­ments. To over­come this major tech­ni­cal hur­dle, small-pore zeo­lite (8-ring) sup­port­ed Cu cat­a­lysts were invent­ed. On the oth­er hand, zeo­lite sup­port­ed Fe SCR cat­a­lysts are more selec­tive in uti­liz­ing NH3 for NOx reduc­tion at high tem­per­a­tures but show a strong depen­dence on the NO to NO2 ratio in the feed gas at low tem­per­a­tures. Sys­tem approach­es were devel­oped to enhance the low tem­per­a­ture SCR activ­i­ty of the Fe SCR cat­a­lysts. As such, both Cu and Fe SCR cat­a­lysts were suc­cess­ful­ly com­mer­cial­ized and applied on lean-burn diesel vehi­cles meet­ing the strin­gent US EPA 2010 emis­sion stan­dards.

Hai-Ying ChenBiog­ra­phy — Dr. Hai-Ying Chen is a Sci­en­tif­ic and Prod­uct Devel­op­ment Man­ag­er at John­son Matthey, where he leads a team of sci­en­tists to devel­op advanced emis­sion con­trol cat­a­lysts and tech­nolo­gies for both gaso­line engine and diesel engine pow­ered vehi­cles to meet the gov­ern­ment emis­sion reg­u­la­tions.

Dr. Chen received his Ph.D. in Chem­istry from Fudan Uni­ver­si­ty, Chi­na. He has pub­lished more than 50 tech­ni­cal papers in peer-reviewed jour­nals and holds 14 US/international patents. He received the Top Cit­ed Arti­cle Award by Catal­y­sis Today for arti­cles pub­lished in 1998, and was a recip­i­ent of the Amer­i­can Chem­i­cal Soci­ety Award for Team Inno­va­tion in 2009. He was named as the 2014 Her­man Pines Award in Catal­y­sis by the Chica­go Catal­y­sis Club and the 2014 Catal­y­sis Club of Philadel­phia Award by the Catal­y­sis Club of Philadel­phia.

2014 Annual Student Poster Competition

This is the first call for posters for the Catal­y­sis Club of Philadelphia’s annu­al Stu­dent Poster Con­test to be held Thurs­day, Octo­ber 16th, 2014 at the Dou­ble Tree Hotel, 4727 Con­cord Pike (Rt. 202) in Wilm­ing­ton, DE. To enter, please sub­mit a short abstract of your pro­posed entry before Sep­tem­ber 28th, 2014, to Bingjun Xu at bxu@​udel.​edu.

The com­pe­ti­tion is restrict­ed to grad­u­ate stu­dents only. Post-docs are wel­come to present their posters but are not eli­gi­ble for prizes. All poster pre­sen­ters should be list­ed as the first author, and will be guests of the Catal­y­sis Club for the evening. As in past years Catal­y­sis Club mem­bers and guests will cast their votes for favorite poster and a pan­el of indus­tri­al judges will select the 5 best posters from the top 10 posters. Total prizes award of $550 will be dis­trib­uted between the win­ners, $150 will go to the over­all win­ner and $100 each to the 4 oth­er win­ners. The one over­all win­ner will be invit­ed to present his or her work at the annu­al Catal­y­sis Club sym­po­sium in Spring 2014.

The Catal­y­sis Club of Philadel­phia is very proud of this event and views it as one of the region’s pre­mier oppor­tu­ni­ties for grad­u­ate stu­dents to show­case their work with the local chem­i­cal indus­try pro­fes­sion­als. All grad­u­ate stu­dents whose work is either direct­ly or indi­rect­ly relat­ed to catal­y­sis sci­ence and tech­nol­o­gy are encour­aged to sub­mit entries. View the offi­cial announce­ment here.
