Provided Qiqihar Mulongwang Porcelain Co., Ltd. with technology and engineering solutions for biomass pellets and coal gasification, and solved the problems of high pollution from burning pure coal and coal-phenol water pollution. In this project, a certain amount of biomass is added to change the coal gasification process, so that the biomass particles not only have the function of reducing phenol water, but also function as a catalyst. The test results show that the fuel gas and components after the addition of biomass are basically close to those of pure coal gasification. Under the catalytic effect of certain biomass fuel, and without the addition of biomass fuel, 3168m3 of gas can be added per day, which can be converted into 1056kg Datong coal, so the catalysis of biomass fuel can improve Datong The conversion rate of coal is 4.4-5%.
