摘要
Abstract
The effects of fuel type and pyrolysis temperature on the physicochemical properties of coal char( C-char)and biomass char were investigated with straw,oak sawdust,and Huating bituminous coal as raw materials. BET,SEM-EDS,XRD,and TGA were used to analyze the coke specimens. Results show that the BET surface area and porous volume of C-char increase as the pyrolysis temperature increases,whereas those of wood char( W-char)insignificantly change,from 600 to 1 000 ℃. Straw char ( S-char)has the largest surface area and pore volume at 800 ℃ as sintering occurs at higher temperatures. As the pyrolysis temperature increases,the C content of char increases and its H and O contents decrease. The ignition characteristic of S-char is superior to those of W-char and C-char. The ignition characteristics of Wood-char and C-char decrease with the increase of pyrolysis temperature. Straw-char exhibits the best ignition characteristic at 800℃.关键词
