Abstract
Stable, zirconia-pillared clays of reduced gallery height, useful as supports for hydroconversion catalysts, are prepared by treating clays with a zirconium compound, a surfactant and water, and compositing the reduced gallery height clay with suitable metal or metals.
Claims4
A hydroconversion process comprising the conversion of feed materials boiling at least about 700.degree. F. wherein the feed is converted at conversion conditions of elevated temperatures and pressures in the presence of hydrogen and a catalyst comprising one or more metals selected from the group consisting of Group VIII metals, Group VI metals, Group 1B metals or mixtures thereof incorporated into a pillared clay comprising zirconium oxide pillars having a gallery height of .gtoreq.4 to .ltoreq.7 Angstroms wherein the clay is selected from the group consisting of swellable smectites and micas and the clay is capable of maintaining at least about 80% of the gallery height after heating to temperatures of >300.degree. C.
