METHOD FOR PRODUCING SPONGE IRON - UNIV CHINA PETROLEUM BEIJING

Title:

METHOD FOR PRODUCING SPONGE IRON

Document Type and Number:

WIPO Patent Application WO/2022/222709

Kind Code:

A1

Abstract:

The present invention provides a method for producing sponge iron. The method comprises the following steps: performing a steam cracking reaction on a cracking raw feedstock containing low-carbon alkane, wherein electricity is used to provide energy for the steam cracking reaction of the cracking feedstock containing low-carbon alkane; separating the product of the steam cracking reaction to obtain mixed gas containing hydrogen, methane and ethane, and ethylene, propylene and/or 1,3-butadiene; mixing the mixed gas with water and/or CO2 and then producing synthesis gas by means of a catalytic conversion reaction, the synthesis gas being used for producing sponge iron, wherein electricity is used to provide energy for the steam cracking reaction of the cracking feedstock containing low-carbon alkane. According to the invention, electricity is used to provide energy for the steam cracking reaction and the catalytic conversion reaction by means of an electromagnetic coil, so that a new use of electricity can be provided, thereby solving the existing problem of excess power. Moreover, providing energy using an electromagnetic coil can make the heat distribution of a reaction tube more uniform, thereby facilitating the control of a reaction temperature and advancement of a reaction.
