Abstract — Forms of car­bon have been known and used com­mer­cial­ly as sup­ports for active met­al (and com­pounds of met­al) cat­a­lysts for many years. It has been found that the dis­tinc­tive prop­er­ties of mul­ti-wall car­bon nan­otube aggre­gates can be uti­lized to pre­pare durable sup­ports for slur­ry and fixed bed cat­alyt­ic appli­ca­tions that show enhanced activ­i­ty in select­ed reac­tions. The activ­i­ty ben­e­fits from the high lev­el of poros­i­ty in the meso­pore range found in the sup­port struc­ture and the fact that the active cat­alyt­ic met­als can be dis­persed effi­cient­ly through­out the car­bon nan­otube sup­port. In addi­tion the sup­ports show increased attri­tion resis­tance and strength.

The pre­sen­ta­tion will dis­cuss sev­er­al appli­ca­tions for car­bon nan­otube sup­ports found in the lit­er­a­ture. Data on phys­i­cal prop­er­ties and spe­cif­ic test results for the hydro­gena­tion of cyclo­hex­ene to cyclo­hexa­ne and the hydro­gena­tion of nitroben­zene to ani­line in com­par­i­son with acti­vat­ed car­bon cat­a­lysts will be shown. Hype­r­i­on Catal­y­sis is the lead­ing pro­duc­er of mul­ti-wall car­bon nan­otubes and can sup­ply con­sis­tent com­mer­cial prod­ucts that can add val­ue to many chem­i­cal process­es.
