STABILIZATION OF BULK CATALYSTS WITH ORGANO-METALLOXANE FRAMEWORK

摘要

Bulk metallic catalyst precursor compositions are provided that include a Group VIB metal, a Group VIII metal, an organic-compound based component, and an organo-metalloxane polymer or gel. The catalyst precursor compositions can further include a binder. Amorphous sulfided catalysts formed from the catalyst precursor compositions are also provided. The catalyst precursor compositions can have a surface area of about 20 m2/g or less.

主权项

1. A bulk metallic catalyst precursor composition comprising:
a Group VIII metal; a Group VIB metal, a combined amount of Group VIII metal and Group VIB metal being about 1 wt % to about 80 wt % on a metal oxide basis; about 10 wt % to about 60 wt % of an organic compound-based component, the organic compound-based component is based on at least one organic complexing agent; and about 1 wt % to about 50 wt % of an organo-metalloxane polymer, organo-metalloxane gel, or combination thereof, the catalyst precursor composition having a surface area of 20 m2/g or less based on BET.
