摘要：生物质是唯一可转化为液体燃料的可再生资源,利用可再生生物质资源替代传统化石资源制备液体燃料及化学品受到越来越多的关注。笔者采用水-正丁醇双溶剂体系构建竹粉水油相液化溶剂体系,在酸催化条件下实现竹粉液化转化及其产物反应分离,研究了油水体系对竹粉液化及油水溶性组分分离的影响。结果表明:液化最佳反应条件为水-正丁醇比例20∶60、反应温度240℃、反应时间60 min、固液比1∶10;最佳反应条件下竹粉转化率为92.5%,水相产率6.6%,油相产率70.5%。正丁醇含量、反应温度及反应时间的提高可以实现水相组分向油相组分转化,从而提高油相组分含量。液化产物分析结果表明,油相组分C元素含量及热值相对于竹粉明显提高,分别提高约1.3及1.9倍;水-正丁醇溶剂体系已基本实现液化产物高热值油相及低热值水相组分的分离。
Biomass is a promising renewable resource that can be converted into liquid fuels and has been attracted more attention to replace the ever diminishing fossil resource. Water/n-butanol mixed solvent was selected for the liquefaction of bamboo meal and separation of the water/oil products of the resulting liquefaction mixture. The optimum liquefaction of bamboo meal were obtained under reaction conditions of water/n-butanol ratio of 20：60, reaction temperature of 240℃, reaction time of 60 min, solid liquid ratio of 1 ： 10, where the conversion was 92. 5%, water phase yield was 6. 6%, and oil phase yield was 70. 5%. Moreover, the yield of oil phase increased with the increasing n-butanol ratio in the mixed solvent, reaction temperature and reaction time. Compared with those of bamboo meal, the carbon content （56. 27 wt% ） and heating value （33.24 MJ/kg） of oil phase significantly improved and increased about 1.3 and 1.9 times, respectively. The above results indicated that water/n-butanol solvent system is an efficient solvent for the liquefaction of bamboo meal as well as the seperation of higher heating value oil products and lower heating value water phase products from the liquefaction mixture.
