【摘要】 将生物质平台化合物转化为液态烷烃燃料是生物质能源化利用的重要环节。由木质纤维素得到的生物质平台化合物通常含较多的氧原子和不饱和键,且碳原子数目较少,不能满足用作液态烷烃燃料的要求。介绍了通过架构C—C键的方法将生物质平台化合物转化为液态烷烃燃料的方法。综述了羟醛缩合反应、加氢烷基化/烷基化反应和安息香缩合等反应,利用这些反应可将生物质平台化合物的碳原子数增加,满足液态烷烃燃料的要求。对架构C—C键将生物质平台化合物转化为液态烷烃燃料提出了展望。更多还原

【Abstract】 The conversion of biomass derived platform molecules into liquid alkane fuels is a key point of the energy-oriented utilization of biomass. However the platform molecules,such as furfural and hydroxymethylfurfural,usually contain many oxygen atoms and unsaturated bonds,but only fi ve or six carbon atoms,which can not meet the requirement of fuels. Therefore,it is necessary for producing the liquid alkane fuels to increase the carbon chain by the forming of C—C bond and then to remove the oxygen atoms and unsaturated double-bonds through hydrodeoxygenation. Thereinto increasing the carbon atom number is the critical step in the transformation of the platform molecules into the liquid alkane fuels. In this paper,we reviewed several methods for the forming of C—C bonds,such as aldol condensation,hydroxyalkylation/alkylation and benzoin condensation,which can convert the small platform molecules into intermediate products containing 9 to 20 carbon atoms and meet the requirement of the fuels.更多还原
