Synthesis of Ni–Mo and Co–Mo–Ni nano-sulfides and their stable catalysis on complicated full-ranged pyrolysis gasoline hydrorefinery

Abstract

A stable nano-sulfide composite catalyst was synthesized and developed to improve the catalysis of classic pyrolysis gasoline hydrorefinery, based on the rigorous requirement of practical full-ranged (FR) feedstock. Through controlling active components on shielded nanosubstrates, the developed nanocatalyst showed superior characteristics over 1000 h of catalytic test, such as 1) high dispersibility of active components, 2) ultrastability under high space velocity (SV) and complex feedstock conditions and 3) better anti-impurity ability.
