我们已经开发出比传统方法（非催化剂、白云石和商业蒸汽重整Ni催化剂）具有更高能效的生物质气化催化剂。在我们的研究中，Rh/CeO 2纤维素气化得到了高产率的合成气使用流化床反应器与间歇进料的纤维素。但由于反应过程中CeO 2的烧结，催化剂失活。为了防止CeO 2烧结，我们进一步改进了催化剂，发现Rh/CeO 2/SiO2对纤维素的气化相当稳定。结果表明，Rh/CeO 2/SiO2催化剂在873 K时可使真实的生物质（木粉）几乎完全气化。这些结果表明，这种催化剂与流化床反应器的结合可以实现节能的生物质气化。
We have developed catalysts for the gasification of biomass with much higher energy efficiency than the conventional methods (noncatalyst, dolomite, and commercial steam reforming Ni catalyst). In our investigation, the Rh/CeO2gave high yields of syngas for cellulose gasification using a fluidized-bed reactor with batch feeding of cellulose. However, the catalyst was deactivated because of sintering of CeO2during the reaction. To prevent the CeO2sintering, we have further improved the catalyst and found that Rh/CeO2/SiO2was quite stable for the gasification of cellulose. It was demonstrated that Rh/CeO2/SiO2gave almost complete gasification of real biomass (wood powder) at 873 K. These results indicate that the combination of this kind of catalyst and fluidized-bed reactor can realize the energy-efficient biomass gasification.
