Preparation of Formed Coke for Blast Furnace Using Kraft Lignin as a Binder

In the steel industry, development of a coke production technology that uses low-grade coal is desired. Decarbonization by use plant biomass also an important option. A candidate formed coke, which produced forming non-coking using binder, followed carbonization. Kraft lignin, by-product in pulp and paper mills potential binder because it aromatic polymer dissolved from wood. this study, thermal powder was blended with softwood kraft lignin at ratios 0 to 20% briquetted cold-pressing or hot-pressing. Then, briquette carbonized 1000°C produce coke. To verify whether has sufficient strength for blast furnace, product subject indirect tensile test. The increased increasing content; however, exceeding target 5 MPa could not be obtained cold forming. briquetting temperature determinant strengthening factor Formed hot-pressing temperatures higher than 150°C 10% pressing pressure 150 successfully attained strength. did always correspond density corresponding indicating products originating play role strongly binding particles. Softwood seems good material high
