ABSTRACT:
Metals deposited on an inert contact material during high temperature decarbonizing and demetallizing of heavy petroleum stocks are inactivated by mixing the contact material with a silica donor and reacting the mixture at high temperature in the presence of steam to induce migration of silica from the donor to mask metal on the contact material.
