1,170,622. Mixed refractory oxide catalysts. BRITISH PETROLEUM CO. 14 Dec., 1967 [10 Jan., 1967], No. 1246/67. Heading B1E. [Also in Division C5] Refractory mixed oxide catalysts are made by partially hydrolysing an alkoxide of Groups II-VI elements, admixing with at an alkoxide of another element from Groups II-VI and completing hydrolysis. Additionally the catalyst may contain a further component selected from Groups I and V-VIII which is different from the refractory oxides resulting from hydrolysis. Examples describe Pd on SiO 2 -Al 2 O 3 , Pt on SiO 2 -Al 2 O 3 , NOT on SiO 2 - Al 2 O 3 and Ni on SiO 2 -Al 2 O 3 .
