• Enhancement of Gasification Rate of Biochar under Low-Temperature Conditions by Directly Supported Catalysts

抄録

This paper reports on gasification rate of potassium-impregnated char. Especially, the effect of direct supported potassium in char on gasification reactivity is described. The gasification kinetic rates of grass and woody biomass-derived char have been revealed by measuring the rate of weight loss during its reaction with CO₂ as a function of temperature. First-order kinetic rate constants are determined by fitting the weight loss data using a random pore model. The experimental results show that the catalytic effect of potassium is observed for not only wood biomass but also grass biomass and the high gasification rate of grass biomass char is appeared i.e., approximately 10 times higher than that of the raw biomass-char by directly supported catalyst. When using grass biochar on which potassium is directly supported, rapid gasification can be carried out at approximately 650-700°C. (When wheat straw is used, a gasification rate of K_p ≈ 0.1/min can be achieved.)
