陕西省生物质能资源潜力及能源化污染物减排评估研究

Evaluation of Biomass Energy Resource Potential and Emission Reduction of Energy-based Pollutants in Shaanxi Province

面对化石能源消耗导致的全球气候和环境问题,发展生物质能有助于调整能源结构和实现“双碳”目标。基于2020年陕西省县级尺度农、林、畜牧业和生活排污统计截面数据,对生物质资源量、能源潜力和减排量进行核算。结果表明,陕西省生物质理论蕴藏量和可收集量为4872.4万t和3861.9万t。生物质能资源潜力为1925.2万tce(标准煤);陕西省使用生物质能发电,CO_(2)、SO_(2)、NO_(x)、N_(2)O、CH_(4)和PM排放量将减少2467万t。陕西省生物质能潜力得到全面开发后,可替代陕西省能源消耗总量15.4%的化石能源。

Facing the global climate and environmental problems caused by fossil energy consumption,developing biomass energy is helpful to adjust the energy structure and realize the goal of“double carbon”.Based on the statistical cross section data of agricultural,forestry,animal husbandry and domestic sewage in Shaanxi Province in 2020,the biomass resources,energy potential and emission reduction were accounted.The results showed that the theoretical reserves and collectable biomass in Shaanxi Province were 48.724 million t and 38.619 million t,respectively.The potential of biomass energy resources was 19.252 million tce(standard coal).Using biomass energy to generate electricity in Shaanxi Province will reduce the emissions of CO_(2),SO_(2),NO_(x),N_(2)O,CH_(4) and PM by 24.67 million t.After the biomass energy potential in Shaanxi province is fully developed,it can replace the fossil energy which accounts for 15.4%of the total energy consumption in the province.
