Method for producing cyclohexane from by-products and off-gas of steel works or coal chemical process

摘要

The present invention relates to a method for producing cyclohexane using a by-product of a steelmaking process or a coal chemical process, and more particularly, to a process for producing benzene from a landscaping flow path generated in a steelmaking process or a coal chemical process. Hydrogen is produced from at least one or more byproduct gas selected from the group consisting of coke gas (COG), converter gas (LDG), FINEX off gas (FOG), and blast furnace gas (BFG) generated in the steelmaking process or coal chemical process step; And a process for the production of cyclohexane by hydrogenation of benzene using the obtained benzene and hydrogen.;
