Thermochemical Biomass Conversion Processes

The changes of anisotropic texture of foreign coals were examined.It was showed that anisotropic texture from Vitrinite is equal to Japanese coals.In medium volatile coals, first star structure appeared, then it was changed to fibrous texture.In low volatile coals, the changes from droplet to completely fibrous texture was shown.Anisotropic texture from inert maceral are classified into Fusitelike and Fragmentary texture.Quantitative analysis of anisotropic texture was examined about coke, which produced in 250kg standard test coke oven.Good correlation was established between anisotropic texture and coke qualities.We insisted that the study for inprovement of coke quality had to pursue the change of anisotropic texture during plastic state.
