摘要
为了解畜禽粪便热解过程析出气体的主要成分以及气体析出规律,该文在30℃/min的升温速率条件下进行了猪粪、牛粪、羊粪和鸡粪的热解试验,利用傅里叶变换红外光谱(FTIR)技术对热解过程中气体产物的排放特性进行了分析。试验结果表明,畜禽粪便气体产物主要在250～500℃析出,其主要成分为H2O,CO,CO2和CH4等,其中H2O、CO和CO2的析出峰为双峰,H2O和CO2均在350℃附近形成最大析出峰,H2O约在150℃形成第1个析出峰,CO2约在710℃附近形成的第2个析出峰,CO在350℃处形成第一个析出峰,其最大析出峰形成于710℃处左右,CH4析出特性为一单峰,在530℃附近形成最大峰值。该文研究结果为热解反应器的设计和优化提供参考。
The gas product evolved from animal manure pyrolysis was studied at a heating rate of 30℃/min by thermogravimetric analysis coupled with fourier transform infrared spectroscopy（FTIR）.Experimental results showed that the gas products mainly evolved at the temperature range of 250-500℃,and the main gas productswere H2O,CO, CO2 and CH4 etc..The evolution curves of H2O showed a peak at about 150 ℃ and another peak at about 350℃.The CO2 evolution curves took on a much higher peak at about 350 ℃ and a small peak at about 710℃.The CO evolution curves took on a peak at about 350℃ and a higher peak at about 710℃,and therewas only one peak at about 530℃ in evolution curves of CH4.The results can provide a reference for design and optimization of pyrolysis reactor.
