Title (EN) ISOMERIZATION PROCESS
(FR) PROCEDE D'ISOMERISATION
Abstract:
(EN) A method for isomerizing a linear alpha olefin mixture comprising vinyl and vinylidine olefins containing from 10 to 35 carbon atoms, comprising: contacting the alpha olefin mixture in the gas or liquid phase with a bed of porous solid acid ctalyst particles comprising gamma lumina having a specific surface area of at least 100 square meters per gram, a pore volume of at least 0.4 cubic centimeter per gram, an average pore diameter of at least 30 Angstroms, a sodium content of less than 0.01 weight percent and an ammonia chemissorption of at least 0.1 millimole per gram, at a reaction temperature in the range of from about 200 °C to about 400 °C, a reaction pressure in the range of from about 15 to about 500 pounds per square inch absolute and a weight hourly space velocity of from about 0.5 to about 20 kilograms of olefin mixture per kilogram of catalyst particles per hour, wherein the reaction temperature, pressure and weight hourly space velocity are selected so as to form a product mixture comprising at least 70 wight percent of di- and tri-substitued internal olefins, at least 20 weight percent of which product mixture are di-substituted internal olefins having a double bond at the fourth or higher numbered carbon atom position and less than 50 weight percent of which are di-substituted internal olefins having a double bond at the second or third numbered carbon atom position, and which has a kinematic viscosity less than 4 cSt measured at 40 °C. and a pour point below -25 °C.
(FR) L'invention concerne un procédé d'isomérisation d'un mélange d'oléfines de vinyle et de vinylidène comportant 10 à 35 atomes de carbone, afin de former un mélange contenant des oléfines internes di- et trisubstituées ainsi que des oléfines internes profondes.
