Abstract: The catalytic pyrolysis tests of bamboo residue were studied at nitrogen atmosphere. 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 CuCl 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.
