Abstract

Specially shaped catalyst particles, for gas phase hydro-forming of petroleum fractions in presence of H2, formed from alumina base material, contain promoter chose from Pt and mixts. of Pt, Rh, Ga, Ge, Ir, Rh, and Zn. The particles are of polylobal (2-5, pref. 3, lobes) cross section shape, where na) shape of lobe is defined by circules (each having equal xia.), (b) the centres of the circles are spaced from each other by 3/8-15/16 dias. of circles. The pref. particles are of di- and tri-lobal shape, and the catalyst metals may also be promoted with chloride ions. The defined particle shapes allow smaller particles sizes to be used (generally giving greater activity) without increasing press. drops.
