Catalytic hydrotreating of 1-methylnaphthalene as a screening test. II

Eight Co/Mo/Al 2 O 3 catalysts from commercial suppliers, along with SnCl 2, have been studied for the hydrotreating of 1-methylnaphthalene (1-MN) in a stirred autoclave at 450 and 500°C. The predominant catalyzed reaction at 450°C is ring hydrogenation (RHG); at this temperature hydrodemethylation...

Description
Summary:Eight Co/Mo/Al 2 O 3 catalysts from commercial suppliers, along with SnCl 2, have been studied for the hydrotreating of 1-methylnaphthalene (1-MN) in a stirred autoclave at 450 and 500°C. The predominant catalyzed reaction at 450°C is ring hydrogenation (RHG); at this temperature hydrodemethylation (HDM) is appreciable but little affected by catalysts, and ring hydrocracking (RHC) is very low. With presulfided catalysts at 500°C, HDM predominates and RHC becomes appreciable; the extent of RHG is much less at 500° than at 450°C. SnCl 2, slightly catalyzes HDM, but it is a very poor catalyst for both RHG and RHC. The RHG activity is much greater at 450°C for all the presulfided catalysts than for the as-received ones. Final autoclave pressure correlates well with the extent of 1-MN conversion by RHG and RHC.
