摘　　要：基于相同的核算边界,分别构建采用A-D-E-RC法制浆联合生物质热电联产与常规碱法制浆联合燃煤热电联产的能量与碳排放模型。通过物流平衡及排放因子法联合实测数据测算出2种制浆联合厂的能耗及碳排放。结果表明,采用A-D-E-RC法制浆联合生物质热电联产工厂的单位产品能耗比常规碱法制浆联合工厂降低了26.8%。其中,碱回收单元降低了51.2%的能耗。采用A-D-E-RC法制浆联合生物质热电联产的单位产品碳排放量为1.72 t CO_(2)/Adt,且93.6%为生物质碳,总碳排放下降了31.6%,表明采用A-D-E-RC法制浆联合生物质热电联产具有显著的节能减排效应,为促进制浆联合企业的绿色可持续发展提供新的策略。Based on the same accounting boundaries,energy and carbon emission models were constructed for a biomass combined heat and power(CHP)plant using the A-D-E-RC pulping method and a conventional alkaline pulping with coal-fired CHP plant.The energy consumption and carbon emissions of the two pulping combined plants were calculated using logistics balance and emission factor methods combined with measured data.The results showed that the unit product energy consumption of the pulping combined biomass CHP plant using the A-D-E-RC method was 26.8% lower than that of the conventional alkaline pulping combined plant,with a 51.2% reduction in energy consumption in the alkaline recovery unit.The unit product carbon emission of the pulping combined biomass CHP plant using the A-D-ERC method was 1.72 tCO_(2)/Adt,with 93.6% from biomass carbon,resulting in a total carbon emission reduction of 31.6%.Using the A-DE-RC method for pulping combined with biomass CHP had significant energy-saving and emission-reducing effects,providing a new strategy for promoting the green and sustainable development of pulping combined enterprises.
