摘　　要：以大豆油为原料,在自制的固定床反应器中,以制备含氧量低的烃类液体燃料为目标,考察以碱性氧化物CaO为催化剂时载气流速、温度、催化剂用量、进料量等诸因素对裂解液组成产生的影响,并采用气质联用仪(GC-MS)表征其组成。结果表明,在不通载气,反应温度450℃,重时空速(WHSV)为0.38 h-1条件下,裂解液收率55.8%,烃类化合物含量81.4%,其中烷烃、烯烃含量达到65.3%,C8以内及C9~C16组分含量分别为46.9%、43.7%;CaO用量的增加能促进大豆油裂解脱羧,有效改善裂解液组成;裂解液经燃料性能测定,表明其具有较好的燃料性能。The liquid hydrocarbon fuel with low oxygen content was produced in self-designed fixed bed reactor using soybean oil as raw material and CaO as catalyst. With basic oxide CaO as the catalyst, the influence of parameters, such as flow rate of carrier gas, reaction temperature, amount of the catalyst, input quantity of raw material etc. on content of pyrolysis liquid was investigated and the main content was analyzed by GC-MS. The results show that under the condition of no carrier gas, reaction temperature of 450 ℃ , weight hourly space velocity （WHSV） of 0.38 h^-1, the yield of pyrolysis liquid is 55.8%, the content of hydrocarbon compounds is 81.4%, including 65.3% alkanes and alkenes, and the content of within C8 and from C9 to C16 carbon chain components are 46.9% and 43.7%, respectively. The catalytic pyrolysis decarboxylation was strengthened and the pyrolysis liquid quality was improved with increase of the CaO amount. Fuel properties of pyrolysis liquid were tested. The results show that it has better fuel performance.
