The research about the effect of metal ratio influence Co/Mo to porosity and acidity of Co/Mo-Ti02 pillared montmorillonite catalyst had been done. Natural montmorillonite was modified with the piilaring agent Ti02 and then followed by Co/Mo impregnation with variation amount of Co:Mo 0:3,9724 g ; 10,9140:13,2414 g ; 16,3710:9,9310 g ; 21,8280:6,6207 g ; 6,5484:0 g. Parameter measured were acid…
