畜禽粪便热化学转换技术的研究进展

A Review on Thermo-Chemistry Conversion of Animal Manure

畜禽粪便污染环境的问题日益突出,但畜禽粪便同时也是一种生物质能源。为探索畜禽粪便能源化途径,详细介绍了畜禽粪便热化学转换技术的国内外研究现状,讨论了直接燃烧、热裂解、液化、气化各种热化学转换技术的优势和劣势。由于气化技术相对成熟且设备投资相对较低,使畜禽粪便气化具有一定的应用前景,建议开展畜禽粪便气化设备、参数优化和气化对环境影响的研究。

Animal manure is one of the important resources of biomass energy, although the issue of environmental pollution caused by animal manure has become serious. To explore the possibility of the innovative approach to convert manure into energy, this paper introduced the research statues of technology on thermo-chemistry conversion （TCC） of animal manure abroad and at home, discussed the advantages and disadvantages of different TTC technologies including direct combustion, pyrolysis, liquefaction and gasification. Gasification is one of the attractive options with its relative low investment and wide application in straw biomass utilization. To speed up the improvement and its application of gasification in manure area, studies of gasification equipment, parameters optimization and environmental impact for animal manure are recommended.
