摘要： A process for preparing a naphtha reforming catalyst has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid (EDTA). The aqueous solution of the chelating ligand and a tin compound is used to impregnate a support, e.g., alumina extrudates. A platinum-group metal is also an essential component of the catalyst. Rhenium may also be a component. A reforming process using the catalyst has enhanced yield, activity, and stability for conversion of naphtha into valuable gasoline and aromatic products.

摘要： A process for preparing catalysts has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid. The aqueous solution of the chelating ligand and a promoter metal salt is first prepared heated to a temperature of about 80.degree. C. to about its boiling point and then combined with an aqueous solution containing a Group VIII metal compound. Next this mixed solution is aged at a temperature of about 40.degree. C. to about 100.degree. C. and then used to impregnate a support, e.g., alumina spheres. The impregnated support is then dried, calcined and reduced with hydrogen. Prior to reduction the catalyst may optionally be treated with a chlorine or chloride stream.

摘要： A novel catalyst for alkylating an alkene with an alkane to give an alkylate product has been developed. The catalyst comprises a refractory inorganic oxide on which is dispersed a Group VIII metal, a metal cation and the reaction product of a metal halide and bound surface hydroxyl groups of the refractory inorganic oxide. The catalyst is characterized in that the Group VIII metal is concentrated in an outer layer of the catalyst particle.
