摘　　要：通过利用已有的炼油设施,可以将加氢脱氧生物油(HDO-oil)和减压蜡油(VGO)在催化裂化(FCC)装置中共炼,以降低生物炼油厂投资成本,进而为生物质燃料生产成本的降低提供新的方法。采用Aspen Plus软件针对共炼过程的FCC装置进行了模拟,用于预测不同共炼条件下的干气、液化气、汽油和柴油等产品的收率;采用7个真实组分与40个虚拟组分分别定义VGO、HDO-oil以及共炼产品的组成;分别将VGO和HDO-oil/VGO(质量比20/80)作为原料进行FCC装置共炼模拟,根据原料、动力学反应器条件及实际数据估计并调整相关参数。通过实验数据与模拟数据的对比,表明模拟数据的误差相对较小。FCC装置共炼模拟的结果显示,HDO-oil的加入使得产品中CO_(2)、CO和H_(2)O的生成量增加。The hydrodeoxygenation bio-oil(HDO-oil)and vacuum gas oil(VGO)can be co-processed in the fluid catalytic cracking(FCC)unit by use of existing refining facilities,which can help reduce the biorefinery investment cost,and provide a new method for reducing the production cost of biomass fuels.Aspen Plus was used to simulate FCC unit in co-processing to forecast the yield of such products as dry gas,liquefied gas,gasoline and diesel under different co-processing conditions.The constitution of VGO,HDO-oil and their co-processing products was defined by 7 real components and 40 pseudo components.FCC co-processing simulation was performed using VGO and HDO-oil/VGO(mass ratio:20/80)as raw materials,respectively,and relevant parameters were estimated and adjusted according to raw materials,KREA conditions and actual production data.The comparison between experimental data and simulation data shows that the error of simulation data was relatively small.The FCC co-processing simulation results show that the addition of HDO-oil can increase the generation of CO_(2),CO and H_(2)O.
