| Description
| - Byly připraveny katalyzátory Co, Mo a COMO s různým poměrem Co/Mo nanesené na SiO2,ZrO2, TiO2, Al2O3, aktivní uhlí a MgO. Aktivita katalyzátorů byla testována při hydrodesulfurizaci benzothiofenu. Přadí aktivity monometalických katalyzátorů Mo bylo MoO3/TiO2, MoO3/C, MoO3/ZrO2, MoO3/SiO2, MoO3/Al2O3 a MoO3/MgO. Pořadí velikosti promočního efektu při přidání Co k Mo katalyzátoru bylo CoMo/MgO, CoMo/C, CoMo/Al2O3, CoMo/TiO2, CoMo/ZrO2, CoMo/SiO2. Synergismus v aktivitě byl doprovázen poklesem selektivity hydrogenace/hydrogenolyza. Hydrogenolyza byla promotována více než hydrogenace a tak na katalyzátorech CoMo se tvořilo méně dihydrobenzothiofenu než na katalyzátorech Co a Mo. Byly měřeny křivky TPR a stupeň redukce koreloval s aktivitou monometalických katalyzátorů Mo. TPR křivky katalyzátorů CoMo byly podobné křivkám Mo katalyzátorů a nebyla zde nalezena žádná korelace s velikostí promočního efektu. (cs)
- The Co, Mo and CoMo catalysts in different Co/Mo ratios supported on SiO2, ZrO2, TiO2, Al2O3, active carbon and MgO were prepared. The catalysts were tested in the hydrodesulphurisation of benzothiophene. The order of activity of monometallic Mo catalysts was MoO3/TiO2 > MoO3/C > MoO3/ZrO2 > MoO3/SiO2 > MoO3/Al2O3 > MoO3/MgO. The order of promotion of MoO3/support by Co addition was CoMo/MgO > CoMo/C > CoMo/Al2O3 > CoMo/TiO2 > CoMo/ZrO2 > CoMo/SiO2. The synergism in activity was accompanied with a decrease of hydrogenation/hydrogenolysis selectivity. Hydrogenolysis was promoted more than hydrogenation and thus less dihydrobenzothiophene was formed on CoMo than on Co and Mo catalysts. The TPR patterns were measured, and the degree of reduction correlated with the activity of monometallic catalysts. The TPR patterns of CoMo catalysts were similar to the patterns of Mo catalysts, and no correlation with magnitude of promotion was found.
