Title:
IRON AND STEEL SMELTING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/227994
Kind Code:
A1
Abstract:
The present invention provides an iron and steel smelting method. The method comprises the following steps: performing a catalytic dehydrogenation reaction on propane, wherein electricity is used to provide energy for the catalytic dehydrogenation reaction; separating the product of the catalytic dehydrogenation reaction to obtain a mixed gas containing hydrogen, methane, and ethane, and ethylene and propylene; and mixing the mixed gas containing hydrogen, methane, and ethane with water and/or CO2 as a catalytic conversion raw material, and producing synthesis gas by means of a catalytic conversion reaction, the synthesis gas being used for iron smelting, and electricity being used to provide energy for the catalytic conversion reaction. According to the present invention, under the circumstances that propane cannot be completely converted in some reaction conditions, catalytic dehydrogenation of propane is combined with steam cracking, and unconverted propane is prepared into methane, ethane, etc. by means of steam cracking; synthesis gas is further obtained by means of reforming and component adjustment, and the synthesis gas is a good raw material for direct reduction of iron.
