Title:
METHOD FOR OPERATING METHANE GAS GENERATION DEVICE, METHOD FOR OPERATING BLAST FURNACE, METHOD FOR PRODUCING METHANE GAS, METHOD FOR PRODUCING HOT METAL, AND METHANE GAS GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/074061
Kind Code:
A1
Abstract:
The present invention provides: a method for operating a methane gas generation device, the method being capable of controlling the deterioration rate of a catalyst by adequately adjusting operational conditions of a methane gas generation device and a blast furnace; and a method for operating a blast furnace. This method for operating a methane gas generation device comprises: a step for generating a methane gas from a starting material gas, which contains a blast furnace gas discharged from a blast furnace, with use of a methane gas synthesis reactor; a step for obtaining the methane concentration in the methane gas; and a step for adjusting the conditions for the generation of the methane gas on the basis of comparison between the methane concentration and a predetermined target value of the methane concentration.
