摘　　要：利用化学溶剂冷凝捕集的方法,使燃气中的焦油颗粒凝结沉积。通过试验,对3种典型的溶剂净化性能进行对比分析,从中筛选出性能优良的溶剂,并试验研究溶剂流量与净化性能的关系,结果表明燃气流速为70m3/h、溶剂流量约为250L/h时,焦油的去除效率达到90%,溶剂的损失可控制在一个较小范围内。According to the tar problem in make tar particles in the gas condense and d biomass gas, chemical solvent condensate trapping way was used to eposit. Tar problem could be solved mostly in this way. In the experi- ment, three typical solvents were comparatively analyzed, and the best solvent was chosen. Then, relationship between flow rate of the best solvent and purification performance was studied. The results show that tar removal efficiency can reach up to 90% when the flow rute of the solvent is 250L/h, also solvent loss will be less.
