摘　　要：利用SEM、XRD、N2吸附法和CO2吸附法,文章考察了在不同操作条件下的气流床飞灰的理化性质,结果表明:飞灰的矿物质熔融现象比高温煤焦明显;飞灰含有丰富的中孔及中大孔,但高温煤焦具有较多的微孔;飞灰的碳晶结构不及高温煤焦的规则。In the study,the physical and chemical properties of three fly ash samples from Texaco gasifiers were investigated by SEM,XRD and N2 and CO2 adsorption method.It was found that the ash fusion of the fly ash was more manifest than coal char;the fly ash was rich in mesopore and macropore,and coal char was rich in micropore;the fly ash carbon exhibited lower graphitization degree than coal chars.
