Technical features:

1. Directly control the temperature of the regenerant in the pre heating stage, with simple control;
2. Improve the reactant oil ratio and catalyst activity;
3. Increasing catalytic reaction to suppress thermal cracking reaction, reducing dry gas, increasing liquid yield, significantly submitting economic benefits;
4. The transformation of traditional lifting pipes only requires the replacement of the pre lifting section, with simple equipment, no need for frame transformation, no change in operating medium, and simple installation with less investment.
