竹笋壳液化处理制备燃料的影响因素研究

Research on Liquefying Process of Bamboo Shoot Shell

竹笋壳由于不可食用,常被丢弃,不仅浪费了宝贵的生物资源,而且污染了环境。以竹笋壳为原料,分别选用乙二醇、丙三醇为液化剂,以浓硫酸、磷酸、氢氧化钠、碳酸钠为催化剂,对笋壳进行液化实验。结果表明,以乙二醇为液化剂、浓硫酸为催化剂时笋壳的液化效果最佳。同时还探讨了反应温度、时间、催化剂对液化率的影响。对液化产物的燃烧热进行测定,结果表明:产物的燃烧值比原料提高了57%,经过适当的加工处理后可以作为工业燃料。

Most of bamboo shells were abandoned because they couldn＇t be used. This was not only waste of biological resources, but polluted the environment. Using bamboo shell as the raw material, ethylene glycol and glycerol as the liquid agent, sulfuric acid, phosphoric acid, sodium hydroxide or sodium carbonate as the catalyst, liquefaction experiments were carried out. The results showed that the best condition was ethylene glycol as the liquid agent, sulfuric acid as the catalyst. The reaction temperature, the reaction time and the catalyst on the liquefaction rate were discussed. And heat of combustion of liquefied products was determined, which the combustion value increased 57% much than raw materials. That would be in favor of making industrial fuel.
