摘　　要：以超稳SSY分子筛负载Ni-W制得加氢裂化催化剂,用于加氢裂化生物正构烷烃(C16、C18),得到以煤油和汽油为主的液体生物燃料,可以提高中油组分收率。通过氮气物理吸附,扫描电镜(SEM),X射线光电子能谱(XPS)等分析手段对催化剂进行了表征。在微型固定床连续加氢裂化反应器上,考察了反应条件对单程转化率和煤油/汽油质量比的影响规律。结果表明:255℃、1.0 MPa、质量空速为0.33 h-1、氢油比为4 000:1的反应条件下,单程转化率达到60%以上,煤油与汽油质量比超过2.0。Ni-W/SSY催化剂活性高,可以用于长链烷烃加氢裂化制备煤油组分为主的液体燃料。The Ni-W/SSY catalyst prepared by incipient impregnation using a super steady Y (SSY) zeolitewas used to produce biofuels mainly composed of bio-kerosene and bio-gasoline from bio-C16 and C18n-alkanes by hydrocracking in which the kerosene yield can be improved. The catalyst was characterized bynitrogen physisorption, scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS).In the continuous hydrogenation on a micro fixed bed cracking reactor, the effect of reaction conditions onthe one-through conversion and the mass ratio of kerosene to gasoline were studied. The results indicatedthat the single pass conversion of n-alkanes exceeded 60% and the mass ratio of kerosene to gasolineexceeded 2.0 when the reaction was carried out at 255 ℃, 1.0 MPa, space velocity (WHSV) 0.33 h-1 andhydrogen-oil ratio of 4 000:1. With its high catalytic activity, Ni-W/SSY can be used to produce kerosenebased liquid fuels using long-chain alkanes as raw materials.
