FCC Fluid Catalytic Cracking
FCC Fluid Catalytic Cracking : A process for converting various heavy liquid petroleum fractions into high-octane gasoline and other fuels. Developed by Universal Oil Products (now UOP) and several oil companies in the 1930s and first commercialized by Standard Oil of New Jersey (now Exxon) at Baton Rouge, LA, in 1942. Continuously improved since then, especially in the mid-1960s with the replacement of the original silica-alumina catalyst by a zeolite. The catalyst is now typically a zeolite Y, bound in a clay matrix. The feed is vaporized and contacted in a pipeline reactor with co-currently flowing microspheroidal catalyst particles. The catalyst is then separated from the hydrocarbon products and is continuously regenerated by burning off the coke in a fluidized bed. The process is licensed by UOP and several hundred units are in operation worldwide
