MIP-CGP special catalyst was used in a 3.0 Mt/a gas oil catalytic cracking unit to carry out industrial test of blending desulfurized residue in a large proportion.Based on the main operating parameters,properties of raw materials and products,material balance and energy consumption during the blending period,the operation of the device was analyzed and summarized.The results showed that the reaction temperature and catalyst scorch were well controlled when the large proportion of desulfurized residue was blended in the MIP process FCC unit,the goal of long-term operation was realized,the energy consumption of the unit was effectively reduced,and the processing load of the unit was increased,which provided an effective way to increase the load of the residue hydrogenation unit and the whole plant.
