| 英文摘要 | Reaction characteristics and kinetics of biochar gasification with steam at temperature(T) of 1123-1223 K and steam partial pressure(SP) of 10%-40% were studied by a micro fluidized bed reaction analyzer (MFBRA). It shows that increasing T and SP was beneficial to shorten reaction time and increase the production of gaseous product (H2, CO and CO2) and total C conversion. At low temperature (1123 K), gasification reaction was greatly affected by SP, especially for H2 with an increase of 1.97 times. At 1223 K and SP鈮?0%, due to the limitation of active sites, SP had little effect. With the increase of T, the volume yield ratio of CO/CO2 showed a trend of first decreasing and then increasing; at 1123 and 1173 K, with the increase of SP, the ratio decreased; while at 1223 K, it basically maintained at 1.25. The generation active energy(Ea) of H2, CO2, and CO under different SP was calculated via shrinking core model, which were in the range of 95.44-101.82, 83.56-89.35 and 70.41-74.86 kJ/mol. The Ea of total C conversion was in the range of 71.29-76.78 kJ/mol. The test results make up for the limitations of existing analyzers that are difficult to determine the gas product generation characteristics and kinetics during the gasification process. 漏 2022, Editorial Board of CIESC Journal.
