Introduction of reforming function of pre reforming catalyst

Catalytic reforming is one of the main processing methods in modern oil refining and petrochemical industry. Its purpose is to rearrange the hydrocarbon molecules in straight run gasoline by using the pre reforming catalyst, so as to improve the octane number of gasoline and produce valuable products while producing aromatics.


The so-called "catalytic reforming" refers to the rearrangement of the molecular structure of hydrocarbons into a new structure: in the presence of pre reforming catalyst, reforming gasoline fraction is called catalytic reforming. The main purpose of catalytic reforming is to produce aromatics such as benzene, toluene and xylene, or to produce high octane gasoline. The reforming process of gasoline under the action of heat is called thermal reforming, which needs to be carried out at a high temperature of 530 to 580 ° C and a pressure of 3 to 7 MPa. Under these conditions, the octane number of gasoline can also be improved, but the yield of this process is low and the product quality is poor.
