为了研究中国原生铝工业的能耗与温室气体排放情况,借鉴国际铝协提出的铝工业能耗及温室气体排放核算框架和方法,对中国原生铝工业进行了相应的核算。结果表明:2005年中国原生铝工业消耗6 578万t标准煤,占全国能耗的2.9%;原生铝电解环节的能耗及温室气体排放分别占原生铝工业总能耗及总温室气体排放的67.7%和82.7%;电能消耗分别为原生铝工业的能耗和温室气体排放贡献71.9%和69.2%。改善电力结构可以有效降低中国原生铝工业的能耗和温室气体排放。
In order to study the energy consumption and greenhouse gas emissions of primary aluminum industry in China, the corresponding accounting of primary aluminum industry in China was made based on the framework and method of energy consumption and GHG emissions accounting proposed by the International Aluminum Association. The results show that in 2005, China’s native aluminum industry consumed 65.78 million tons of standard coal, accounting for 2.9% of the national energy consumption. The energy consumption and greenhouse gas emissions of the primary aluminum electrolysis sector accounted for the total energy consumption of primary aluminum industry and total greenhouse gas emissions 67.7% and 82.7% respectively; and the electricity consumption contributed 71.9% and 69.2% of the energy consumption and GHG emissions of the primary aluminum industry respectively. Improving the power structure can effectively reduce energy consumption and greenhouse gas emissions in China’s native aluminum industry.
