畜禽粪便是一种重要的生物质资源，可以通过热解产生沼气。粪肥含有不同的组分和碱金属含量，这可能增加热解的复杂性。采用热重-傅里叶变换红外光谱-质谱联用技术（TGA-FTIR-MS），比较了不同畜禽粪便中碱金属对畜禽粪便热解特性及热解产物性质的影响。五种畜禽粪便由于组分和碱金属含量的不同，表现出不同的热解特性。高碱金属含量的猪粪（SM）、肉鸡垫料（BL）和蛋鸡垫料（LL）均表现出一个热解峰，催化降低了活化能;牛粪（DM）和牛粪（BM）表现出两个重叠的热解峰。SM、BL和LL的CH 4第二释放峰比DM和BM的更强，对应于SM、BL和LL的C双键O和C单键O单键C/C单键C的吸收强度比DM和BM的低。不同热解终温下生物质炭和有机质的红外光谱分析表明，生物质炭中特征峰的衰减与热解产物的变化相对应。SM释放的H2量最高，CH 4产率也较高，表明SM比其他动物粪便更适合热解气化生产沼气。
Livestock and poultry manures are important biomass resources that can produce biogas by pyrolysis. Manures contain varied components and alkali metal contents, which may increase the complexity of pyrolysis. The influence of alkali metals in raw manure on the pyrolysis characteristics and the properties of the released gaseous product between different livestock and poultry manures were compared by thermogravimetric analysis coupled with Fourier-transform infrared spectroscopy and mass spectrometry (TGA–FTIR–MS). Five livestock and poultry manures showed different pyrolysis characteristics caused by the different components and alkali metal contents. The high alkali metal contents of swine manure (SM), broiler litter (BL), and layer chicken litter (LL), each of which showed one pyrolysis peak, catalytically reduced the activation energy; dairy manure (DM) and beef manure (BM) from cattle showed two overlapped pyrolysis peaks. The second release peaks of CH4for SM, BL, and LL were more intense than those of DM and BM, corresponding to the lower absorption intensities of Cdouble bondO and Csingle bondOsingle bondC/Csingle bondC for SM, BL, and LL compared to those of DM and BM. The FTIR spectra of raw manures and biochars obtained at different final pyrolysis temperatures showed that the decreased absorptions of characteristic peaks in the biochars corresponded to the variations in the gaseous products. SM released the highest volume of H2and a high CH4yield, indicating that SM is more suitable for biogas production by pyrolysis gasification than other animal manures.
