Gasoline octane number in catalytic cracking units
Thread Content
What is the octane rating of the gasoline produced by catalytic cracking units? It’s usually between 89.5 and 90
Previously, with 90-octane gasoline, catalytic cracking gasoline could be used after only slight processing; but as the quality of the product improved and various specifications became more stringent, catalytic cracking gasoline had to go through further refining processes in order to meet the standards for gasoline intended for distribution.
