采用三元金属催化剂组份进行烃转化 U.S._(3、839、193) C.A._(82) _(75416)S 制备了一种用于汽油重整含铂铱锗和卤素载于多孔载体上的酸性催化剂。例如载体是按U.S._(2、620)、314)专利所用方法制备。以G_eCl_4的乙醇溶液和H_2PtCl_6,氯铱酸的HCl水溶液混合所得混和溶液作为载体的浸渍液。浸渍温度为70°F以产生含组份为0.375Pt,0.375Ir,0.5Ge的产物。产物在225°F蒸去过量溶液,干燥的颗粒于
USING (3,839,193) CA_ (82) _ (75416) S A catalyst for gasoline reforming of platinum-containing iridium-germanium and halogen on a porous support was prepared Acid catalyst. For example, the carrier is prepared by the method used in the U.S. Patent No. 2,620,314. The mixed solution of G_eCl_4 in ethanol and H_2PtCl_6 and chlorotridium acid in HCl aqueous solution was used as the impregnation solution of the carrier. The impregnation temperature was 70 ° F to produce a product containing 0.375 Pt, 0.375 Ir, 0.5 Ge components. The product is distilled off excess solution at 225 ° F and the dried granules are allowed to cool
