摘　　要：以硬脂酸钠为原料,在熔融氢氧化钠体系中,以制备含氧化合物含量低的烃类液体燃料油为目标进行裂解实验,分别考察反应温度、载气流速和进料速率对裂解液组成的影响。对所得裂解液采用GC-MS进行分析,可得其成分主要为烷烃、烯烃、部分芳香烃及少量含氧化合物。在反应温度425℃,载气流速0.7 L/min,进料速率1.4 g/min的条件下,裂解液中各组分的含量为烷烃60.2%,烯烃32.5%,芳香烃4.2%,含氧化合物3.1%。In order to reduce the content of oxygen-containing compounds in liquid fuel, this paper mainly reports on pyrolysis experiments of sodium stearate to produce liquid hydrocarbon fuel carried out in a self-designed reactor with molten alkali. The influences of parameters as reaction temperature, rate of carrier gas and rate of feed are investigated and the main composition distributions of liquid pyrolysate are analyzed by GC-MS. The results indicates that in the case of pyrolysis of sodium stearate with molten alkali, a number of alkenes and alkanes and some aromatics are formed, a few undesired oxygen-containing compounds are found in the pyrolysate. Under the condition of temperature 425 ℃, carrier gas 0.7 L/min and rate of feed 1.4 g/min, the content of each component of pyrolysates are alkanes 60.2%, alkenes 32.5%, aromatics 4.2%, oxygen-containing compounds 3.1%
