Control sulfur levels in FCC products

摘要

Fluid catalytic cracking (FCC) naphtha is the primary source of gasoline-pool volume and sulfur content. This blending stream is an important contributor to the gasoline octane pool. One challenge in refining is to produce ultra-low-sullfur gasoline (ULSG) with FCC naphtha while still protecting octane-rich olefins and aromatics.
