| Abstract: | The application of maximizing propylene catalyst LCC-2 in a heavy oil fluidized-bed catalytic cracking(FCC) unit of 1 400 kt/a was introduced.The calibration results showed that when LCC-2 was used,the yield of liquefied petroleum gas(LPG) increased form 13.76% to 22.99%,and the content of propylene in LPG increased from 5.10%(for feedstock) to 6.99%.The production statistical results showed that the yield of propylene increased from 5.10% to 6.99% after transformation,the output of propylene was increased by 28.35 kt/a for processing capacity of 1500kt/a in FCC unit,and the increment profit of 80 million yuan per year could be obtained. |
