CATALYSTS OF THE HYDROCARBONS CONVERSION FOR LONG-CHAIN α-OLEFINS OBTAINMENT
Abstract
A literature review on the catalysts, used in the hydrocarbons conversion to produce a-olefins, is given in the article. The catalysts derived from natural raw materials are considered as the most accessible ones. Methods of decationization and modification of dinoptiUolite, the main component of natural zeolites of Russia and Kazakhstan, are described. Montmorillonite clay is used as a carrier. The most attention in the cracking catalysts review was drawn in the direction of the paraffin cracking with obtainment of long-chain a-olefins. The production of long-chain a-olefins by the oligomerization of ethylene and propylene, where Bronsted and Lewis acids are used as catalysts, is shown along with cracking. In addition to natural and synthetic zeolites, heteropoly acid (HPA) is also used in the catalysts production.
