| Abstract: | 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. |
