ABSTRACT:
A naphtha-reforming catalyst is prepared by using aluminum hydroxide as a feed stock, which is acidificated in steam at high temperature, then shaped and calcined to form .gamma.-Al.sub.2 O.sub.3 support which is supported with metals of Pt, Re and Ti and halogens. The Pt content is 0.075-0.8 Wt %, Re/Pt ratio is 0.1-3.0 (Wt.). Since the .gamma.-Al.sub.2 O.sub.3 support having high purity, high crystallinity and concentrated middle pores has been adopted, the activity, selectivity and stability of the catalyst are increased considerably while the Pt content decreased.
