The catalytic vapor-phase isomerization, hydrogenolysis, and/or disproportionation of trimethylbenzen (TMB) over Co-Mo/Al2O3 and Ni-W/Al2O3 was studied at 480°C, 400 psi reactor pressure, and a constant H2 flow. Each catalyst was run in the reduced or sulfided form. The results show a marked difference in the product distributions for each catalyst, which is attributed to differences in the catalysts’ acidities.
The hydrodenitrogenation (HDN) of quinolone and the hydrodesulfurization (HDS) of benzothiophene were also studied. The compounds were reacted in a 1 liter autoclave at 325°C and varying partial pressures of H2. The same supported metal catalysts used in the TMB study were evaluated in the reduced or sulfided forms for HDN and HDS activity. The differences in activity and selectivity of the two catalysts are correlated with the acidity determined by the TMB probe reaction.
