To study the kinetics of coal and straw during co-gasification,Shenfu bitumite and wheat straw were blended in different ratios and then pyrolyzed to get blends char.The synergistic effect in the pyrolysis process of blends and the comparison of reactivity in the blends char-CO2 gasification process were investigated by TGA,and the kinetics of both processes was analyzed with Coats-Redfern method.The results show that the pyrolysis temperature of bitumite and wheat straw is different;Co-pyrolysis demonstrat...
