A process for the processing of low carbon alkanes

Abstract

The application discloses a processing method of low-carbon alkane. The method comprises the following steps: (1) mixing low-carbon alkane with hydrogen and passing through a hydroconversion reaction zone, wherein the hydroconversion reaction zone is filled with a hydroconversion catalyst containing ZSM-5 molecular sieve; (2) passing the hydroconversion reaction effluent of step (1) into a high-pressure separator to obtain hydrogen-rich gas and liquid-phase effluent, wherein the liquid-phase effluent is passed into a separation system to obtain ethane, propane and n-butane. The method can effectively convert isomeric alkane in low-carbon alkane into small-molecule n-alkane, and improve the quality of ethylene raw material.
