Fluid catalytic cracking octane gasoline

A fluid catalytic cracking unit in Joliet, Illinois, converts bea components of crude oils into high octane gasoline and distillates. (Corbis Corporation)... 

The modem gasolines are produced by blending products from cmde oil distillation, that is, fluid catalytic cracking, hydrocraking, reforming, coking, polymerization, isomerization, and alkylation.Two clear examples of the possible use of solid-acid catalysts in refining processes are the isomerization of lineal alkanes and the alkylation of isobutene with butanes. In both these cases, and due to the octane... 

Fluid catalytic cracking (FCC) units for producing high-octane gasoline from gasoil or naphta see Section 7.2. 

Octane barrel yield a measure used to evaluate fluid catalytic cracking processes defined as (RON + MON)/2 times the gasoline yield, where RON is the research octane number and MON is the motor octane number. 

Fluid coking and fluid catalytic cracking (FCC) are mechanically similar The products of fluid coking and delayed coking are the same (i.e., coke and distillate products), but the equipment is physically different. Alkylation of the three- and four-carbon molecule products from these units is commonly performed to convert them to branched chain gasoline, which increases the octane rating. As can be seen from Figure 1.1 in Chapter One, the feed to fluid catalytic crackers is a gas-oil distillate. For delayed cokers and fluid cokers, the feed is residium.

Fluid catalytic cracking is one of the most important processes in the petroleum refining industry. The process cracks gas oil to produce high-octane-number gasoline. The Type IV industrial design consists of two bubbling fluidized beds with continuous catalyst circulation between the two vessels ...
