ABSTRACT:
An improved reforming process is obtained using a catalyst containing platinum, rhenium and chloride disposed on a particulate support formed using alumina obtained by removing water from an aluminum hydroxide produced as a by-product of a Ziegler higher-alcohol synthesis, when the catalyst is prepared by calcining the alumina support at a temperature between 1000.degree. -1500.degree. F to provide a support having a surface area between 140-240 m.sup.2 /g, then impregnating a platinum compound and a rhenium compound into the calcined alumina in the presence of a sufficiently high concentration of chloride to obtain an impregnated composition, which, upon drying, contains at least 1.4 weight percent total chloride, and finally calcining the impregnated preparation to reduce the total chloride content of the final catalyst to less than 1.2 weight percent.
