碱金属碱土金属对神府煤焦气化活性的影响
Effect of AAEM on gasification reactivity of Shenfu char
摘要
Abstract
The gasification reactivity and crystallite structure of Shenfu char were measured via thermogravimetric analysis ( TGA) and X-ray diffraction technology ( XRD) to investigate the catalytic effect of AAEM during CO2 gasification. The interest was focused on effects of loading method ( pyrolysis before loading or pyrolysis after loading) , catalyst species ( Na, K, Ca) and loading amount (1%, 3%, 5% on metal atom) . For Na and K, the reactivity of char pyrolyzed before loading catalyst is better than that pyrolyzed after loading. The order of catalytic efficiency is Na~K>Ca. In addition, catalytic efficiency of AAEM catalyst increases with the increasing of loading amount. Catalyst addition inhibits the progress of char graphitizing during pyrolysis. The order of inhibition is K>Na>Ca, and the inhibition is enhanced with the increase of loading amount.关键词
