Abstract: The industrial application of assistant HOB-A in 1.05 MM TPY MIP-CGP catalytic cracking unit of a company was introduced. The results showed that when the mass fraction of HOB-A was 9.3%, compared with the blank calibration, the yield of gasoline increased from 38.32% to 38.57%,the research octane number increased from 93.5 to 94.5,the octane number of gasoline barrel was increased by 1.73%,the yield of propylene increased from 9.23% to 9.77% ,the total liquid yield increased by 0.86 percentage point. The economic benefits before and after the use of assistant HOB-A were calculated. After the use of assistant, the economic benefits of catalytic cracking unit were greatly improved.
