摘要：在常压固定床反应器中，以生物质炭为原料进行水蒸气气化制取合成气研究。实验在温度800～1000℃和水蒸气流量0．083～0．285g／（min·gchar）条件下进行，反应时间为15min，研究反应温度和水蒸气流量对生物质碳转化率、合成气产率及合成气组分的影响。研究结果表明：生物质炭水蒸气气化具有很高的反应活性，气体产率在0．40—2．97L／g之间；温度和水蒸气流量对碳转化率和合成气热值及组分影响显著；在反应温度1000℃、水蒸气流量0．285g／（min·gchar）时，碳转化率达到最高值78．7％；气体产物主要由H2、CO、CO2和CH。组成，合成气热值在8．9—9．6MJ／Nm’之间，合成气中（H2＋CO）在68％～80％之间，（H2／CO）在3．1～6．4之间。
Steam gasification of biomass-derived char was studied at atmospheric pressure in a fixed bed reactor. Experiments were carried out at 800, 850, 900, 950 and 1000~C with different steam flow rates in the range of 0. 083 to 0. 285g/（ min＇g char） and a reaction time of 15rain. The effects of temperature and steam flow rate on conversion of char, synthesis gas yield, heat value and its compositions were mainly studied. It has been found that biomass-derived char was highly reactive, particularly at high temperature, synthesis gas yield was in the range of 0. 40-2.97L/g. The results show that steam flow rate and temperature have strong effects on the conversion of char, synthesis gas yield, heat value and its compositions. The conversion of this char was maximum（78.7% ）at 1000~C with steam flow rates of 0. 285g/（ min.g char）. The product gas obtained was mainly a mixture of H2, CO, CO2, and CH4. Under the present reaction conditions, synthesis gas （ H2 ＋ CO） produced by steam gasification of char was in the range of 68-80mo1%. The low heating value of the product gas was in the range of 8.9-9.6MJ/ Nm3 , and the （ HJCO ） was about 3.1 - 6.4. The results suggest that there is a strong potential for producing synthesis gas from steam gasification of biomass-derived chars.
