Abstract: The deactivation rate for a supported acidic catalyst, especially for a supported acid catalyst such as a supported HF.SbF5 catalyst, used in a process for isomerizing a feed comprising methylcyclopentane, cyclohexane, or mixtures thereof, at low temperature, is sharply reduced by including sufficient isobutane in the feed so that the feed isobutane content is 25 to 75 weight percent.
Abstract translation: 负载型酸性催化剂，特别是用于负载型酸催化剂如负载型HF.SbF5催化剂的失活速率通过包括在低温下异构化包含甲基环戊烷，环己烷或其混合物的进料异构化的方法而急剧减少 进料中足够的异丁烷使得进料异丁烷含量为25至75重量％。

Abstract: AN ALKYLATION PROCESS FOR PRODUCING JET FUEL FROM HYDROCARBONS WHICH COMPRIES (A) CONTACTING AN ISOPARAFFIN FEEDSTOCK WITH AN OLEFIN FEEDSTOCK IN THE PRESENCE OF HYDROFLUORIC ACID AT A TEMPERATURE BETWEEN ABOUT 30* AND 100* F. IN A REACTION ZONE, (B) MAINTAINING THE RATIO OF ISOPARAFFIN TO OLELIN BELOW 2.0 IN SAID REACTION ZONE, AND (C) WITHDRAWING FROM SAID REACTION ZONE AN EFFLUENT CONTAINING AT LEAST 10 WEIGHT PERCENT HYDROCARBON BOILING BETWEEN ABOUT 300* AND 550*F.,EXCLUSIVE OF ANY ACID OIL PRODUCED IN SAID REACTION ZONE.

Abstract: A process for producing a high-octane gasoline having reduced smog-forming tendencies, which comprises: A. THERMALLY DEHYDROGENATING-CRACKING ISOBUTANE TO OBTAIN PROPYLENE AND ISOBUTENE; B. HYDRATING PROPYLENE TO OBTAIN ISOPROPANOL; C. ETHERATING THE ISOPROPANOL WITH THE ISOBUTENE TO OBTAIN TBUTYL ISOPROPYL ETHER; AND D. BLENDING THE T-BUTYL ISOPROPYL ETHER WITH GASOLINE-BOILINGRANGE HYDROCARBONS. Preferably the thermal dehydrogenation is carried out under conditions, specifically including a temperature between about 1125* and 1275*F., to produce a molar ratio of isobutene to propylene between 1.0 to 1.25.

Abstract: A process for the esterification of isobutene with reduced polymerization of the isobutene which comprises contacting the isobutene with a lower carboxylic acid and an acidic resin catalyst containing a sulfonate group, which catalyst has between about 0.2 and 2.4 meq. of H+ per gram of catalyst. Preferred carboxylic acids include formic acid and acetic acid and the preferred type catalyst is a resinous sulfonated polystyrene divinyl benzene copolymer.
