摘　　要：以厌氧消化所产生的沼气为研究对象，进行了沼气干式脱硫生产试验。结果表明，温度对沼气脱硫的影响很显著，当脱硫塔的温度为25～40℃时，控制好其他运行参数，脱硫效率一般都在90％以上，满足沼气风机和沼气锅炉的要求；脱硫剂连续再生时，其对O2的吸收率为50％～70％：脱硫剂的硫容可达到30％以上。Production test of dry desulphurization from the biogas produced by anaerobic digestion was carried out. The results show that the impact of temperature on desulphurization is very significant. When the temperature of desulphurization tower is 25 to 40 ℃, with controlling the other operating parameters well, the desulphurization efficiency is generally above 90% , meeting the requirements of biogas blowers and boilers. In the process of continuous regeneration of desulphurization agent, the uptake rate of oxygen is 50% to 70%. The absorption capacity of desulphurization agent is above 30%.
