Synthesis of Porous NiMo Sulphide Act as HDS Catalyst by Alcohol Supercritical Drying Technique

Abstract:

Porous NiMo sulphide was successfully synthesized from ethanol supercritical fluid drying technique using (NH₄)₂MoS₄ and Ni(NO₃)₂ as the precursors. It was shown that the NiMo sulphide had extremely high porosity and the specific surface area was 322 m²•g^-1. The results of DBT hydrodesulfurization experimental showed that the porous NiMo sulfide prepared had high HDS activity, which was 2.78 times higher than that of a commercialized supported catalyst.
