The preparation of NiS/SiO2-Al2O3 catalyst template KH-Phthalate was carried out by adding anhydrous nickel metal into the catalyst supported by SiO2-Al2O3 template KH-Phthalate by impregnation, then the calcination process was carried out for 4 hours at a temperature of 700ºC. Furthermore, the sulfidation process used ammonium sulfide gas for 2 hours at a temperature of 500ºC. The purpose of…
