摘要:
在小型固定流化床中,分别以低温费-托合成重质油,以及减压蜡油与减压渣油(二者质量比为7∶3)混合物为原料,在催化裂化或催化裂解催化剂(二者牌号分别为LIP-300,LHP-A)作用下进行了相应的反应。结果表明:在反应温度为500 ℃,催化剂/原料油(简称剂油比,质量比,下同)为4,反应压力为0.1 MPa,质量空速为15 h-1的常规催化裂化条件下,与混合原料油相比,低温费-托合成重质油的液化气和丙烯收率分别增加了11.25,3.89个百分点,丙烯/液化气(质量比)提高了0.04个单位,后者裂化性能优于前者。另外,以费-托合成重质油为原料,在反应温度为500 ℃,剂油比为6,反应压力为0.1 MPa,质量空速为10 h-1的最佳催化裂化条件下,汽油收率最高可达60.37%;在反应温度为590 ℃,剂油比为7.84,反应压力为0.1 MPa,质量空速为10 h-1的最佳催化裂解条件下,三烯收率可达52.29%。
Abstract:
In a small fixed fluidized bed,the corresponding reaction was carried out with the low temperature Fischer-Tropsch synthetic heavy oil or the mixture of vacuum wax oil and vacuum residue (mass ratio of 7∶3) as feedstock with catalytic cracking(FCC) or catalytic pyrolysis catalyst(their corresponding brands of LIP-300 and LHP-A respectively).The results showed that compared with the mixed raw oil,the yields of the liquefied petroleum gas(LPG) and propylene using Fischer-Tropsch synthetic heavy oil as feedstock had increased by 11.25,3.89 percentage points respectively,and propylene/LPG(mass ratio) had increased by 0.04 units,under the conventional FCC conditions of reaction temperature of 500 ℃,catalyst/oil(mass ratio) of 4,reaction pressure of 0.1 MPa,and weight hourly space velocity (WHSV) of 15 h-1.The cracking performance of latter was superior to the former.In addition,with Fischer-Tropsch synthetic heavy oil as feedstock,the yield of gasoline was up to 60.37% under the optimum FCC conditions of reaction temperature of 500 ℃,catalyst/oil(mass ratio) of 6,reaction pressure of 0.1 MPa and WHSV of 10 h-1;the yield of triene was 52.29 % under the optimal catalytic pyrolysis conditions of reaction temperature of 590 ℃,catalyst/oil(mass ratio) of 7.84,reaction pressure of 0.1 MPa,and WHSV of 10 h-1.
