Catalytic Reforming Process

It mainly includes two processes of raw material pretreatment and reforming, and for the purpose of producing aromatics, it also includes aromatics extraction and rectification devices. The pretreated raw material enters the reforming section (see figure), is mixed with circulating hydrogen and heated to 490-525°C, and then enters the reactor at 1-2 MPa. There are 3 to 4 reactors in series, with a heating furnace in between to compensate for the heat absorbed by the reaction. The material leaving the reactor enters the separator to separate the hydrogen-rich cycle gas (the excess part is discharged), and the obtained liquid is used as reformed gasoline after the light components are removed from the stabilizing tower, which is a high-octane gasoline component (research octane number 90 or more), or sent to the aromatics extraction unit to produce aromatics.
