AM-94-43 DEEP CATALYTIC CRACKING, MAXIMIZE OLEFIN PRODUCTION

Description:

The Fluid Catalytic Cracking (FCC) unit has long been the dominant co,nversion process in U.S. refineries. Traditionally, the FCC has served as a major source of high octane naphtha for blending in the gasoline pool. The yield of gasoline had to be maximized and light ends were often considered as a by-product. Recent environmental regulations coupled with lead phase out have shifted the focus of the FCC from that of an octane barrel machine to that of a light olefins generator. The light olefins are the necessary feedstock for premium reformulated gasoline (RFG) blending components such as MTBE, TAME and alkylate.
