Title:
OPERATING METHOD OF METHANE GAS GENERATOR, OPERATING METHOD OF BLAST FURNACE, PRODUCING METHOD OF METHANE GAS, PRODUCING METHOD OF HOT METAL, AND METHANE GAS GENERATOR
Document Type and Number:
Japanese Patent JP2023067262
Kind Code:
A
Abstract:
To provide an operating method of a methane gas generator and an operating method of a blast furnace, enabling a deterioration rate of a catalyst to be controlled by appropriately adjusting operating conditions of the blast furnace and the methane gas generator.SOLUTION: An operating method of a methane gas generator comprises a step of generating a methane gas from a raw material gas including a blast furnace gas discharged from a blast furnace using a methane gas synthesis reactor, a step of measuring a methane concentration in the methane gas, and a step of adjusting the conditions for generating the methane gas based on a comparison between the methane concentration and a predetermined methane concentration target value.SELECTED DRAWING: Figure 1
