Abstract
Abstract Cracking catalysts or catalyst supports prepared from mixtures comprising colloidal alumina, colloidal silica, a particulate weighting agent, and/or an active catalytic component possess excellent catalytic and physical properties. The catalysts in accordance with the invention also show excellent resistance to metal poisoning, and are also highly useful in non-cracking and/or hydroconversion processes.
