AI Technical Summary

⚠Technical Problem

There is a need for the development of novel bulk catalyst compositions with improved hydrotreating activity, particularly in processes such as hydrodesulfurization and hydrodenitrogenation, as existing catalysts do not meet the desired performance levels.

⚗Method used

A bulk catalyst precursor comprising specific weight percentages of Ni, Mo, W, Y, and optionally Cu, Ti, and/or Nb, which is prepared by mixing metal oxide precursors with an organic compound and a protic liquid under controlled conditions to form a precipitate, followed by sulfurization, resulting in a catalyst with enhanced activity.

🎯Benefits of technology

The catalyst exhibits improved hydrotreating activity and selectivity, effectively processing hydrocarbon feeds under hydrogenation conditions, including hydrodesulfurization and hydrodenitrogenation.

Abstract

A polymetallic bulk catalyst and a method for synthesizing the same are provided. The polymetallic bulk catalyst contains nickel, molybdenum tungsten, yttrium, and optionally copper, titanium, and / or niobium. The catalyst is useful for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.
