畜禽粪便热解气体的红外光谱分析

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。

Fourier transform infrared spectrum analysis of gas product from animal manure pyrolysis

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 products were 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 there was only one peak at about 530℃ in evolution curves of CH4. The results can provide a reference for design and optimization of pyrolysis reactor.
