摘要
在日处理量2000t生物质快速热解工厂的基础上,利用Aspen Plus软件建立完整的生物油精炼提质制汽柴油的流程模型,采用生物油的催化加氢和加氢裂解及产品回收模拟生物油的精炼提质过程。选择水、丁烯酸、对苯二酚、糠醛、羟基丙酮、纤维二糖、左旋葡聚糖、二苯并呋喃以及二甲氧基二苯乙烯等化合物组成的混合物代表生物油,经催化加氢过程后,各组分产率分别为:加氢油41.39%,水52.73%,小分子气体5.88%,与文献结果对比,基本符合实际生产情况。得到的加氢油进一步加氢裂解,最终回收到汽油组分产品8540kg/h,柴油组分产品10907kg/h,以原材料生物质为参考标准,产率分别为10.25%和13.09%。通过对生物油精炼提质过程各模块的能量参数分析可知,以初步生物油为原料,生产1kg的汽柴油产品需要消耗电能3.989MJ,消耗蒸汽热能1.664MJ,总耗能5.653MJ,将能量折算成标准煤用量后,生产1kg汽柴油产品的能耗相当于0.4319kg标准煤。
Based on a biomass fast pyrolysis plant that is capable of processing 2000 tons of biomass per day,researchers developed a model to simulate the complete process of refining and upgrading bio-oil to make gasoline and diesel fuel using Aspen Plus software,involving the catalytic hydrogenation and hydrocracking of bio-oil as well as product recycle.A compound comprising water,butenoic acid,hydroquinone,furfural,acetol,cellose,levoglucosan,dibenzofuran,dimethoxy 2 styrene,etc.was used to represent bio-oil.The yields of various components after catalytic hydrogenation are ：hydrogenated oil 41.39%,water 52.73% and small-molecular gases 5.88%.The results basically accord with production facts after being compared with literature.The hydro-genated oil obtained was further hydrocracked and 8540kg/h of gasoline components and 10907kg/h of diesel fuel components were eventually recovered.The yields of these two types of products were 10.25% and13.09%,respectively,with the feedstock biomass used as the benchmark.An analysis of the energy parameters of each module of the bio-oil refining and upgrading process shows that using preliminary bio-oil as the feedstock,production of 1kg of gasoline and diesel fuel products consumes 3.989 MJ of electric power and1.664 MJ of steam heat.The total energy use is 5.653 MJ.The energy use in producing 1kg of gasoline and diesel fuel products is equivalent to 0.4319 kg of coal.
