应对气候变化背景下洁净煤技术发展趋势

The Clean Coal Technology Trends Based on Global Climate Change Background

全球气候变暖已经是一个不争的事实,气候变化的原因除了自然因素以外,与使用化石燃料过程中排放CO_2的质量分数密切相关。在此基础上以低能耗、低污染为基本特征的低碳经济的概念日益受到追捧,带动了相关领域的科技创新。减少碳排放的技术创新,离不开能源技术的进步。对技术主流和技术发展趋势的判断就变得非常重要。重点分析了发电行业中的CO_2减排技术。在比较了提高能效类技术,新型发电技术,直接减排或捕捉CO_2技术,可再生能源和核电等技术之后,提出了近期、中期和远期的技术发展方向。

Global warming is an inconvenient truth.The green-house effect gas,especially CO_2 emission reduction give rise to worldwide attention,and related technique innovations are driven by the Low Carbon Economic concept.It is critical to predict the technology trend and select the path.CO_2 reduction techniques in the power generation industry are analyzed.The short-term,mid-term and long-term technology directions are discussed after a brief comparison between several types of technologies.
