FUEL GAS PRODUCING METHOD AND TAR PRODUCING METHOD FROM BIOMASS THERMALLY CRACKED OIL, METHOD FOR RECOVERING SENSIBLE HEAT POSSESSED BY COKE OVEN GAS, METHOD FOR RECOVERING SENSIBLE HEAT POSSESSED BY CONVERTER GAS, AND METHOD FOR INCREASING CALORIFIC VALUE OF CONVERTER GAS

摘要

PROBLEM TO BE SOLVED: To provide a fuel gas producing method, producing a fuel of high quality from a biomass thermally cracked oil obtained by thermally treating biomass without increasing the cost, a method for effectively recovering sensible heat possessed by coke oven gas, and a method for increasing combustion calorific value of converter gas. SOLUTION: The fuel gas producing method from biomass thermally cracked oil comprises bringing a biomass thermally cracked oil generated by thermally treating biomass into contact with a coke oven gas from a coke oven 1 and thermally decomposing the biomass thermally cracked oil to thereby generate a fuel gas.
