摘要: Abstract Owing to automotive fuels market and environmental regulations, FCC unit operators are looking for a step increase of diesel yield quality. In this manuscript, the conversion vacuum gas oil (VGO) is discussed from point view relative cracking rates VGO LCO different class components present in feed. Although paraffinic feeds has potential forming high quality diesel, they not well suited operation since give low with common catalysts. Feeds containing one two-ring molecules may be best options acceptable if at moderate conversion, through temperature recycle operation. Finally, three more rings should avoided concentration aromatic cores cracked hardly avoided, conducing worst light cycle (LCO) regards cetane particulate emissions.
