Abstract Rapid heat transfer in molten metal can enhance biomass gasification, and combining this with catalysts can lower the process temperature and eliminate tar formation. The aim of this work was to investigate the effects of Sn-Bi molten metal and its catalytic enhancement with Ni/Al2O3 with respect to synthesis gas (H2 + CO) production by biomass pyrolytic gasification. Cellulose and aspen wood pyrolysis was performed between 500 °C and 800 °C at high and low heating rates. The proposed combined medium was effective for pyrolytic gasification, lowering the pyrolysis temperature, increasing the H2 content of the product gas, and decreasing the CH4 concentration. The combined medium also reduced the char content and eliminated tar at a high heating rate, improving the carbon conversion efficiency. The proposed medium was thus effective for biomass gasification.

用于合成气生产的 Sn-Bi 熔融金属中的生物质热解

摘要 熔融金属中的快速传热可以促进生物质气化，将其与催化剂结合可以降低工艺温度并消除焦油形成。这项工作的目的是研究 Sn-Bi 熔融金属及其与 Ni/Al2O3 的催化增强对通过生物质热解气化生产合成气 (H2 + CO) 的影响。纤维素和白杨木热解在 500 °C 和 800 °C 之间以高和低加热速率进行。所提出的组合介质对热解气化有效，降低了热解温度，增加了产物气体的 H2 含量，并降低了 CH4 浓度。组合介质还降低了炭含量并在高加热速率下消除了焦油，提高了碳转化效率。
