摘　　要：催化热解制备左旋葡萄糖酮(LGO)是生物质制备高值化学品的重要方法。开发了一种新型的金属磺化炭催化剂用于高效制备LGO,并研究了热解温度、催化剂与生物质的比例以及金属盐类型对左旋葡萄糖酮生成的影响,研究表明:金属磺化炭明显促进了LGO的选择性,在Ce-SC催化剂作用下,催化热解温度为300℃、原料/催化剂比例为1∶1时,LGO的含量达到了82%;在Co-SC催化剂作用下,催化热解温度为400℃、原料/催化剂比例为1∶1时,LGO的含量达到了64%。Preparation of levoglucosenone(LGO)by catalytic pyrolysis is an important method for biomass to prepare high-value chemicals.A new type of metal sulfonated carbon catalyst was developed for the efficient preparation of LGO.The effects of pyrolysis temperature,catalyst-to-biomass ratio,and the type of metal salt on LGO production were studied.The results indicate that the sulfonated carbon impregnated with metal significantly promoted the selectivity of LGO.Under the action of Ce-SC catalyst,when the catalytic pyrolysis temperature was 300℃and the raw material/catalyst ratio was 1∶1,the LGO content reached 82%.Under the action of Co-SC catalyst,when the catalytic pyrolysis temperature was 400℃and the raw material/catalyst ratio was 1∶1,the LGO content reached 64%.
