摘要: |
该文以现有研究文献为基础,对生物质能源的能值分析、生命周期评价和生命周期能值分析研究现状进行了综述,所涉及的生物质能源产品包括生物质厌氧发酵产品(沼气)、生物质气化燃气、生物质发电、生物质致密成型燃料、燃料乙醇、生物柴油等。能值分析方法在生物质能源系统的应用主要体现在对其能源效率、环境效率和可持续性等方面的评价;生命周期评价在生物质能源系统的实证研究主要包括对系统生命周期内的能量投入、产出以及环境排放和经济性等方面的分析和评价。结果表明,在国内外生物质能源研究方面,单一的能值分析和生命周期评价都取得较丰硕的研究成果,所涉及的生物质能源类别也较为全面。但生命周期评价与能值分析相结合的研究还较为薄弱。最后提出了进一步完善生物质能源能值分析及其生命周期评价的建议。 |

Abstract: |
This paper,based o nthe current researches,summarized the research progress
of emergy analy-sis,life cycle assesment,and the emergy analysis of life cycle in evaluating biomass
energy.The biomass energy referred to biomass anaerobic fermentation product (biogas),biomass
gasification gas,biomass power generation,biomass briquette fuel,biomass
ethanol,biodiesel,and so on.The method of energya nalysis in the application of biomass
energy system mainly reflected the energy efficiency and environment efficiency evaluation.The empirical research of life cycle assesment on biomass energy system mainly re-flected energy input-output analysis,economic and environmental analysis,as well
as emissions reduc-tion.The results showed that the single energy analysis and life cycle assesment had got fruitful achieve-ments at home and abroad.The research field had covered various kinds of biomass energy production. However,the research on combination of life cycle assesment and energy analysis in biomass energy eval-uation was relatively weak.At last,some suggestions were put forward to improve the combination of
both method (life cycle assesment and energy analysis)in biomass energy evaluation. |
