摘　　要：由于化石能源的紧缺性和不可再生性,该文对热解油加氢催化制航空燃料进行研究。松木热解油在Pt/SAPO-11催化剂的作用下,进一步加氢制备航空燃料,探究反应氢压力、温度、空速和氢油比对催化反应效果的影响。在单因素实验的基础上,根据Box-Behnken的中心组合实验设计响应面法研究氢压力、温度、空速对C_(8)~C_(16)烃的选择性影响。结果表明:优化后最佳的工艺条件为:氢压10.24 MPa、温度404.25℃、空速1.42 h^(-1),在此条件下,C_(8)~C_(16)烃的选择性为48.97%。通过验证得到C_(8)~C_(16)烃的选择性为48.69%,接近预测值,表示模型可靠。Due to the scarcity and non-renewability of fossil energy,this paper explored the catalytic hydrogenation of pyrolysis oil to produce aviation fuel.Pine pyrolysis oil was used to produce aviation fuel by one-step hydrogenation method under the action of Pt/SAPO-11 catalyst.The effects of pressure,temperature,space velocity and hydrogen oil ratio on the catalytic reaction were investigated.Based on the single factor experiment,Box-Behnken central composite design of response surface methodology was applied to study the effects of pressure,temperature,space velocity and hydrogen oil ratio(hydrogen volume/palm oil volume)on the selectivity of C_(8)-C_(16) hydrocarbons.The result show that the optimal process conditions for response surface optimization are:pressure of 10.24 MPa,temperature of 404.25℃,space velocity of 1.42 h^(-1).Under these conditions,the selectivity of C_(8)-C_(16) hydrocarbon is 48.97%.And the selectivity of C_(8)-C_(16) hydrocarbons was verified to be 48.69%,which is near to the predicted value and indicates that the molel is reliable.
