Catalytic cracking Friedel-Crafts catalysts

Most of the studies reported on the catalytic cracking of plastics use PE as starting material because it is the main polymer in plastic wastes. The first works appeared in the 1970s,8 mostly based on the use of Friedel-Crafts catalysts. 

McAfee of Gulf Refining Co. discovered that a Friedel-Crafts aluminum chloride catalyst could catalytically crack heavy oil. 

Fluidized Catalytic Cracking (FCC) owes its origins to the 1915 discovery by A. M. McAfee of Gulf Refining Co. (now part of Chevron) that a Friedel Craft aluminium chloride catalyst could catalytically crack heavy oil. Since those early days, the vehicle for catalytic cracking has evolved from fixed beds to moving beds to fluidized beds. 

Frjedel-Crafts Reaction. Any organic reaction brought about by the catalytic action of anhydrous aluminum chloride or related, so-called Lewis acid type catalysts. Discovered in 1877 by C. Friedel and J.M. Crafts, who later uncovered most of the types of reaction such as substitution, isomerization, elimination, cracking, olefin polymerization, addition, etc. Commonly used to displace an aromatic hydrogen atom with an alkyl, aryl or acyl chain...
