Abstract
Abstract A synthetic halloysite which is substantially iron-free is obtained by crystallization from a reaction mixture containing hydrous alumina gel and aqueous silica sol. Metal substituted synthetic halloysites can be prepared by coprecipitation of metal hydroxides with the alumina gel. Hydrocarbons are converted over cracking catalysts derived from these halloysites.
