摘要：

The influence of inorganic matter on the pyrolysis of Japanese cedar (Cryptomeria japonica) wood was studied at a gasification temperature of 800 degrees C with demineralization through acid washing. Some influences on the formation of char, tar, and low molecular weight products coincided with results reported at temperatures lower than the gasification temperature. However, the carbonization behavior of the volatile products and the yield of polysaccharide fraction were not able to be explained as a sum of the pyrolysis of cellulose, hemicellulose, and lignin even after demineralization. These results suggest some interactions between wood constituent polymers other than the influence of inorganic matter.
