摘要: 通过钙基固硫剂CaO对煤粉固硫的固硫实验研究和固硫体系的热力学计算，发现高温下固硫产物CaSO4不稳定，但加入助剂Al2O3后，由于复合产物的生成，可以抑制CaSO4的分解，从而增加高温下CaO对煤粉的固硫效率。
Abstract: Based on the experimental study on the sulfur fixation of calcium-based sulfur fixation agent CaO on pulverized coal and the thermodynamic calculation on the sulfur fixation system, it was found that the sulfur fixation product CaSO4 was unstable at high temperature. However, compound products would be formed with the addition of Al2O3, and it could inhibit the decomposition of CaSO4, thus increase the sulfur fixation efficiency of CaO on pulverized coal at high temperature.
