摘要：以玉米废弃油脂为原料,进行热裂解反应并对其产物进行分析,结果表明:液体燃油产率随着裂解温度的升高而升高,当裂解温度为520℃时收率可达81.3%;裂解后含水量和黏度显著降低,含水量由1.8%降至0.5%,运动黏度由88.16 mm2/s降至7.46 mm2/s,热值有所提高,由38.6 MJ/kg升至40.6 MJ/kg,产物酸值由原料的65 mg/g升高到144 mg/g;通过气质和红外分析表明,裂解后的液体燃油主要含羧酸和烷烃,其中羧酸含量为74%,烃类含量为21%;气相色谱分析表明,裂解产生的气体主要为碳氢化合物、CO2和CO,可燃气体的总含量为80.78%。同时,结合分析结果,讨论了该热化学转化过程的机理。
Using corn waste oil as raw material,thermal cracking reaction was performed. The analysis of the reaction and its product showed that the yield of liquid fuel rised with the increase of pyrolysis temperature. The yield could reach 81. 3 % when the pyrolysis temperature was 520 ℃. Moisture content and viscosity decreased significantly after cracking. Moisture content decreased from 1. 8 % to 0. 5 %,and viscosity decreased from 88. 16 mm2/s to 7. 46 mm2/s. Meanwhile,calorific value increased from 38. 6 MJ /kg to 40. 6 MJ /kg. The acid value of product rised to 144 mg /g compared with 65 mg /g of the raw material. The analysis of GC-MS and IR indicated that the liquid fuel mainly contained carboxylic acid and paraffin. The carboxylic acid content was 74 %,and the hydrocarbon content was 21 %. GC analysis showed that the gas produced in the thermal cracking mainly contained hydrocarbons,CO2and CO. The total content of combustible gas was 80. 78 %. In addition,the mechanism of thermal chemical conversion process was analyzed.
