Abstract: Isobutane is alkylated with ethylene in the presence of HCl promoted aluminum chloride alkylation catalyst; ethyl chloride is a by-product formed and recovered from the hydrocarbon effluent in a normal butane - ethyl chloride fraction. The normal-butaneethyl chloride fraction is pyrolyzed at 400*-1,000* F with bauxite catalyst to form ethylene, hydrogen chloride along with normal butane; the normal butane is separated from the mixture, by condensation, and the remaining vapor stream of ethylene and hydrogen fluoride is recycled to the alkylation reaction.
Abstract translation: 在HCl促进的氯化铝烷基化催化剂存在下，将异丁烷与乙烯烷基化; 氯乙烷是在正丁烷 - 氯乙烷馏分中从烃流出物形成和回收的副产物。 正丁烷 - 氯乙烷馏分用铝土矿催化剂在400°-1000°F热解，与正丁烷一起形成乙烯，氯化氢; 通过缩合将正丁烷与混合物分离，并将乙烯和氟化氢的剩余蒸气流再循环至烷基化反应。

Abstract: IMPROVED METHOD FOR RECOVERING SULFURIC ACID FROM USED SULFURIC ACID CONTAINING WATER AND HYDROCARBON WHEREBY USED ALKYLATION ACID IS BLENDED WITH SPENT ACID OF RELATIVELY HIGH HYDROCARBON CONTENT OBTAINED BY REACTING USED ALKYLATION ACID WITH AN ALIPHATIC OLEFIN TO FORM DIALKYL SULFATE WHICH IS EXTRACTED FROM THE SPENT ACID WITH ISOBUTANE. THE BLEND OF THE TWO ACIDS IS BURNED IN A SLUDGE CONVERSION PROCESS AND THE SULFUR VALUES RECOVERED AS STRONG SULFURIC ACID.
