催化作用下流化床中煤部分气化的试验研究

Experimental Research on Partial Gasification of Coal in Fluidized Beds in the Presence of Catalysts

在1台小型常压流化床气化炉上进行空气和水蒸汽存在条件下的煤部分气化试验,研究石灰石、碳酸钠和白云石3种催化剂对煤气组分、热值、煤气产率和碳转化率的影响。试验结果表明:添加催化剂能够有效地提高煤气质量、煤气产率和碳转化率,其中碳酸钠的催化效果最好,石灰石次之,白云石最差。

Experiments of partial gasification of coal in the presence of air and steam were carried out in a small atmospheric fluidized bed furnace. The catalytic effects of limestone, sodium carbonate and dolomite on gas composition, on heating value and gas yielding rate, were studied. Test results indicate, that the gas quality, the gas yielding rate and the carbon conversion rate can effectively be raised by the addition of catalysts, among which sodium carbonate is most effective, limestone less and dolomite least.
