<p>1502915 Hydrodesulphurization catalysts UOP Inc 30 June 1975 [1 July 1974] 27449/75 Heading C5E [Also in Division B1] Sulphur-containing fuel oils are hydrodesulphurized at a hydrogen pressure of 7-200 atm., a hydrogen to hydrocarbon vol. ratio of 150-10,000, a temperature of 100-450‹ C. and a LHSV of 0À5-20 using a catalyst comprising a Group VIB component (i.e. Cr, Mo or W) and a Group VIII component (e.g. Fe, Co, Ni, Pt or Pd) on a refractory carrier, wherein the catalyst has been prepared by a specified process involving partial incorporation of the active components by mixing in finely divided form with the carrier to form a dough then extruding and completion of active component incorporation by impregnation of the calcined extrudate (see Division B1). The examples describe the treatment of a vacuum gas oil of boiling range 315-565‹ C.</p> |
