ABSTRACT:
A process for the catalytic reforming of a naphtha fraction is disclosed. A naphtha fraction and hydrogen are commingled and passed in contact with an alumina-supported reforming catalyst at reforming conditions. The alumina support is characterized by a novel method of preparation affording an improved reforming process. The preparation comprises admixing an alpha-alumina monohydrate with an alkaline solution having a pH of at least about 7.5 and forming a stable suspension. A salt of a strong acid, or a solution of a salt of a strong acid, is admixed with the suspension to form a paste or dough which is subsequently extruded, dried and calcined to form said alumina support.
