AI Technical Summary

Technical Problem

Existing carbon-supported materials and catalysts are difficult to prepare with highly dispersed metal sulfide active phases, and traditional oil-soluble catalysts have low metal concentrations, resulting in insufficient hydrogenation activity and making it difficult to achieve whole-phase dispersion in hydrocarbon feedstock hydrogenation reaction systems.

Method used

An oil-soluble organometallic compound was subjected to a sulfidation reaction with a sulfidating agent and hydrogen under hydrocracking conditions to form a metal sulfide and metal oxide catalyst supported on a carbon-based support. The carbon-supported hydrogenation catalyst was obtained by solvent extraction and drying.

Benefits of technology

It improved the hydrogenation activity of the catalyst, enhanced the cracking rate, desulfurization rate, and denitrification rate of the hydrogenation products, and increased the distillate oil yield.
