A catalyst based on platinum - rhenium - alumina to the reforming of a naphtha charging

摘要

A process for reforming a naptha feedstock by contacting the feedstock at reforming conditions with a catalyst containing 0.01 to 5 weight per cent platinum disposed on an alumina support wherein the alumina is obtained by removing water from aluminum hydroxide produced as a byproduct from a Ziegler higher alcohol synthesis reaction and wherein the alumina is calcined so as to have a surface area of 140-240 square meters per gram. Preferably the catalyst also contains rhenium disposed on said byproduct alumina. Preferably the alumina is calcined at a temperature between about 1,150 DEG and 1,300 DEG F. prior to disposing the platinum and/or rhenium on the alumina.
