A novel approach for high efficient conversion of the CO(2)-rich bio-syngas into the CO-rich bio-syngas was carried out by using biomass char and Ni/Al(2)O(3) catalyst, which was successfully applied for production of bio-methanol from bio-oil. After the bio-syngas conditioning, the CO(2)/CO ratio prominently dropped from 6.33 to 0.01-0.28. The maximum CO yield in the bio-syngas conditioning process reached about 1.96 mol/(mol CO(2)) with a nearly complete conversion of CO(2) (99.5%). The performance of bio-methanol synthesis was significantly improved via the conditioned bio-syngas, giving a maximum methanol yield of 1.32 kg/(kg(catalyst)h) with a methanol selectivity of 99%. Main reaction paths involved in the bio-syngas conditioning process have been investigated in detail by using different model mixture gases and different carbon sources.
采用生物质焦和 Ni/Al(2)O(3)催化剂，提出了一种将富 CO(2)生物合成气高效转化为富 CO 生物合成气的新方法，该方法成功应用于从生物油生产生物甲醇。生物合成气调节后，CO(2)/CO 比从 6.33 显著降至 0.01-0.28。在生物合成气调节过程中，CO 的最大产率约为 1.96mol/(mol CO(2))，CO(2)的转化率接近 100%(99.5%)。通过调节生物合成气，显著提高了生物甲醇的合成性能，在催化剂质量空速为 1kg/(kg(catalyst)h)时，甲醇的最大产率达到 1.32kg/kg，甲醇选择性为 99%。通过使用不同的模型混合气和不同的碳源，详细研究了生物合成气调节过程中的主要反应路径。
