An aluminum phosphate AlPO4 has been synthesized so as to substitute for alumina as support of CoMo sulfide aimed to hydrotreatment Loading with CoMo oxides decreases the density of Brøonsted sites, whereas that of Lewis sites increases in connection with the dehydration activity for 2-butanol. The pH of the impregnating solution of Mo ions affects the density of Lewis acid sites, and the proportion of monomeric and polymeric oxides. The best sulfided CoMo/AIPO4 catalyst for thiophene hydrodesulfurization is obtained for a pH of 6. The activity is compared to that of commercial CoMo/Al2O3 catalyst.
