    1518034 Hydrocarbon isomerisation catalyst COMPAGNIE FRANCAISE DE RAFFINAGE 11 Aug 1976 [13 Aug 1975] 33494/76 Heading BIE [Also in Division C5] A hydrocarbon isomerisation catalyst comprises the reaction product of (a) a refractory mineral oxide carrier with a platinum group metal and also titanium, zirconium, tungsten or molybdenum deposited on it together with a combined halogen, with (b) aluminium trichloride/bromide, ferric chloride/bromide, beyllium dichloride, zinc dichloride or zirconium dichloride. The catalyst is prepared by impregnation with solution(s) of the above metals followed by aftertreatment with the metal halides. The use of alumina as carrier is exemplified.

    3E C / - Cg at a hydrogen pressure of 1-100 atm, molar ratio of hydrogen: hydrocarbon 0.5: "-O, flow rate of 0.1-10. The catalysts tested in the isomerization process show increased activity and selectivity (conversion of pentane reaches 0-60%. Example 1. The refractory carrier used for all of the catalysts listed is alumina, which has the following {characteristics: Specific surface, MVr j , Pore volume, cm / g Average pore radius Chlorine content (measured by X-ray fluorescence) Weight L Oh, from alumina oxide Form Expression Average diameter, This oxide is calcined for hours when various metals are deposited and called then aluminum oxide as a carrier. ® Preparation of control catalysts T1 and T2. Alumina is immersed in a broken solution of 0.1N hydrochloric acid. After dehydration at room temperature, alumina contacts the circulating solution of chloroplatinic acid, the initial concentration of platinum. in which such a catalyst contains G, 0.35 weight L of platinum. After dehydration, it is dried at 120 ° C and calcined in a muffle furnace. It is then subjected to a treatment that makes it possible to regulate the content of chlorine in it. For this purpose, a gas stream containing water vapor and hydrogen chloride is passed through it, for k hours. Then, the obtained solid is calcined for 1 hour at the same temperature. Then the solid is subjected to reduction with hydrogen for 1 h at. It contains 1.36 chlorine and 0.33 platinum. To obtain two control catalysts, the solid is divided into two parts, which are independently treated with aluminum chloride. 13 g of each part is washed with a stream of sublimated aluminum trichloride and hydrogen / the total pressure of the gas stream is 1 atm, the partial pressure of aluminum trichloride is 30 Torr. For the first part, which forms the catalyst T1, the treatment is carried out for 2 hours and 30 minutes with, for the second part, which forms the catalyst T2, - 2 hours and 30 minutes at 500 ° C. The two parts are then treated with a stream of anhydrous nitrogen to remove unreacted aluminum trichloride. Two control catalysts of T1 and T2 are obtained. Preparation of catalysts A1, A2, B1, B2, .0 and D. 100 g of aluminum oxide are impregnated with 250 cm of a solution containing 20 cm of hydrochloric acid and the amount of the compound of titanium, molybdenum, zirconium or tungsten c is calculated. depending on the resulting catalyst. Weight and compounds are given in table. one.
