摘　　要：介绍了一种催化燃烧法治理聚丙烯腈炭纤维生产工艺中含氰废气的工艺。催化剂是以硅的氧化物等为载体,负载有多种过渡金属化合物,对HCN的完全转化温度是200℃,产物为N2、CO2、H2O等无害气体,基本不含NOx。在200℃,实际使用条件下HCN的转化率可达到99.7%。A kind of catalytic combustion technology for treating the HCN-containing waste gases was introduced. This technology has been successfully used in the treatment of HCN-containing exhaust gases generated in the production of PANbased carbon fibers, in which the catalyst was prepared by supporting several transition metal compounds on siliceous oxide. It has been found that at a low temperature of 200 ℃,99.7% of the HCN in the exhaust gases can be transformed into nontoxic species such as N2,CO2 with little NOx.
