摘要 在250mL的高压反应釜中对五种不同种类的农作物废弃物进行了液化研究.以花生壳作探索实验,重点考察了温度、时间、催化剂用量等因素对液化行为的影响,并给出了五种农作物的液化结果.研究结果表明,给料比为10g原料/100mL水时,在300℃~340℃、10min、K2CO3添加量为1/30(催化剂/原料)的条件下,五种农作物废弃物液化获得的重油产率为21%~28%.对产物的高热值进行分析表明,农作物废弃物液化重油具有较高的热值,液化促进了能量分化,是农作物废弃物转化为生物燃料的有效手段. Direct liquefaction of 5 agricultural residues was carried out in a 250 mL autoclave. During the tentative experiment, peanut shell was tested. The influence of reaction temperature, reaction time and catalyst etc. was investigated. The results show that 21% - 28% of heavy oil yield is obtained under the conditions of 300°C - 340°C, 10 min and 1/30 (K2CO3 catalyst/raw material, w/w), when feedstock is 10 g sample mixed with 100 mL water. A linear correlative model gives the correlation coefficient of 0.89, which denotes that the heavy oil yields have a good relationship with the lignin contents in agricultural residues. The heavy oils obtained from the liquefaction of agricultural residues have high heating values. This work shows that liquefaction is an effective way to convert agricultural residues to bio-fuels.
