摘要:

用石灰石作为脱硫剂在热输入0.1 MW的加压喷动流化床试验台上进行了煤部分气化过程中的炉内脱硫试验研究。系统地考察了温度、压力、钙基脱硫剂粒径、钙硫摩尔比等参数对脱硫效率的影响。试验结果如下:随着温度的升高、压力的增加,脱硫效率均提高,但增长幅度减缓。随钙硫摩尔比的增加,脱硫效率提高,但当Ca/S(摩尔比)=2后,继续增大Ca/S,脱硫效率提高有限。脱硫剂粒径减小,脱硫效率提高。

Abstract:

Experimental study of removing hydrogen disulfide was carried out in a 0.1 MW thermal input pressurized spout-fluid bed during coal gasification.The effects of temperature, pressure, particle size of calcium-based desulfurizer and molar ratio of Ca to S were systematically investigated.The desulfurization efficiency increased with increasing temperature and operation pressure but the extent of increase became weaker.The desulfurization efficiency increased with increasing molar ratio of Ca to S, but did not increase greatly when the molar ratio of Ca to S was more than 2.The desulfurization efficiency increased with decreasing particle size of desulfurizer.
