Strategies for catalytic octane enhancement in an FCC unit
- W.R. Grace and Company, Columbia, MD (USA)
Gasoline quality is largely determined by motor and research octane numbers. There is good correlation between octane number and the structure of the C{sub 5} to C{sub 12} hydrocarbons typically present in gasoline. For paraffins, octane number decreases as molecular weight increases with degree of branching. The same is true of olefins. Catalytic strategies for making high octane gasolines include decreasing the amount of higher molecular weight, less branched paraffins, isomerizing paraffins to a more highly branched product, and producing more olefins or aromatics. A number of catalytic processes in current use make use of these strategies, including reforming, isomerization, dimerization, alkylation and fluid catalytic cracking (FCC). The subject of this paper is to discuss the catalytic strategies available to produce octane number in the FCC unit.
