Industrial Application of Octane Rating Additive HCSO in Catalytic Cracking Units
The industrial application of octane number additive HCSO was carried out on a 1.4 Mt/a catalytic cracking unit.The results showed that under the similar operation conditions and compared with the results of blank calibration(before adding enhancer),when the octane number enhancer reached 1.52%of the system inventory,octane number of catalytic gasoline and hydrogenated gasoline increased 0.8,1.2 respectively.According to the PONA analysis data of gasoline,the olefin content decreased by 1.33%,the aromatics content decreased by 0.2%,and the isomeric alkanes increased by 1.62%.From the application situation,the octane number additive HCSO still has a good effect even at low dosage,which can save costs for refineries and bring considerable economic benefits.
