METAL HYDRIDE MODIFIED ALUMINIUM AND/OR SILICON OXIDE COMPOSITIONS AND PROCESS FOR THEIR PREPARATION

摘要

The invention relates to a process for preparing an aluminium oxide and/or silicon oxide gel composition having bonded thereto magnesium oxide, barium oxide or zirconium oxide, characterized in that a substantially anhydrous aluminium and/or silicon oxide gel is contacted with powdered magnesium hydride, barium hydride or zirconium hydride in a slurry phase with slurrying medium being an anhydrous, non-hydroxyl-containing organic liquid, whereby the hydride reacts with the said gel, and subsequently the gel is dried to remove the organic liquid.
