chinois. 在氮气气氛下对竹废屑快速催化热解进行试验,考察氯化亚铜和二氧化钛2种催化剂对竹废屑热解产物的影响,包括对气态产物成分和液态产物丙酮萃取液成分分布的影响。通过对比试验可知,2种催化剂对竹废屑热解的气态产物成分均产生影响,在550℃的热解温度下,氯化亚铜的催化作用使得气态产物中可燃性气体的含量为74.25%。液态产物的丙酮萃取液富含苯酚类物质,其中2,6-二甲氧基苯酚的含量最高为22%以上,且氯化亚铜的催化作用可进一步促进该物质的生产,使得2,6-二甲氧基苯酚的含量增加到27.09%,但总苯酚类物质的含量降低;而二氧化钛的加入对液体产物成分的影响不明显。竹废屑二氧化钛催化热解的固态产物是一种复合型生物质炭材料,在环保领域具有广泛的应用前景。

The influence of two catalyst on the product of bamboo scrap pyrolysis was investigated, including influences on the distribution of the composition of gaseous state product and liquid product by acetone extraction. By comparing the results of the tests, two catalyst all influences on composition of gaseous state product ; in 550℃ pyrolysis temperature, the content of combustible gas reached 74.25% by CuC1 catalysis. Liquid product by acetone extraction is rich in phenol kind material, the content of 2,6-dimethoxy-phenol is high up to 22% , and the catalysis of CuCl further promote ketone formation, the content of 2, 6-dimethoxy-phenol is up to 27.09% , and the content of phenol is decreased by the catalysis, but the influence of TiO2 is not distinct. The solid product of pyrolysis of bamboo scrap with TiO2 is a type of composite charcoal,which will show great prospects in the environmental conservation field.
