The thermal cracking experiment research of tar from rice hull gasification for power generation

Abstract

The tar from rice hull gasification for power generation which is cracked in high temperature is studied in this paper, the results reveal the part of compositions which have smaller RT in tar is first cracked into H2, CO2and carbon, and then carbon react with H2 and CO 2, and CH4, CO are formed; the cracked efficiency of tar can reach 28.66%, the carbon deposit among cracked tar can reach 12.76%, the results of the GC-MS analysis showed the aromatic extent of tar and carbon content of un-cracked tar increase. The pressure drop of cracking reactor increases with tar cracking reaction carrying out in high temperature.
