摘要
阐述了近年来以生物质为原料厌氧转化生物燃气(氢气和甲烷的统称)技术的研究进展。有效的生物质预处理是生物燃气生产的基础,包括物理、化学及生物等各种有效的预处理手段。影响高效生物燃气生产的因素包括环境、发酵底物、菌种、反应器设计等。细胞表面工程、微生物混合群落分析、细胞荧光定量分析等技术的发展会进一步促进生物燃气的高效生物转化技术的发展。从经济学角度考虑,氢气和甲烷发酵联产将最大程度提高生物质原料的利用率。在生物燃气发酵生产过程中,必须考虑整个过程从原料开始到最终的生物燃气和废渣的利用,从系统工程考虑生产和产物综合利用问题。
This paper describes the recent research progress on the production technology of biological fuel gas from biomass by anaerobic biological transformation. The production basis of biological fuel gas is effective biomass pretreatment, including physical, chemical and biological pretreatment. The effective production of biological fuel gas will be influenced by some factors, e.g. environmental conditions, fermentation substrates, strains, reactor designs, etc. The technological development of cell surface engineering, mixed community analysis, and cell fluorescence quantitative analysis will further improve the conversion technology of fuel gas with high efficiency. From economic point of view, combined fermentation production of hydrogen and methane will greatly increase utilization ratio of biological raw materials. During the fermentation process, the whole production process, from raw materials to fermentation products including waste utilization should be comprehensively considered from system engineering point of view.
