The current article focuses on gasification as a primary disposal solution for cellulosic wastes derived from chicken farms, and the possibility to recover energy from this process. Wood shavings and chicken litter were characterized with a view to establishing their thermal parameters, compositional natures and calorific values. The main products obtained from the gasification of chicken litter, namely, producer gas, bio-oil and char, were also analysed in order to establish their potential as energy sources. The experimental protocol included bomb calorimetry, pyrolysis combustion flow calorimetry (PCFC), thermo-gravimetric analyses (TGA), differential scanning calorimetry (DSC), Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, elemental analyses, X-ray diffraction (XRD), mineral content analyses and gas chromatography. The mass and energy balances of the gasification unit were also estimated. The results obtained confirmed that gasification is a viable method of chicken litter disposal. In addition to this, it is also possible to recover some energy from the process. However, energy content in the gas-phase was relatively low. This might be due to the low energy efficiency (19.6%) of the gasification unit, which could be improved by changing the operation parameters.
本文重点研究气化作为一种主要的处理方法，用于处理来自养鸡场的纤维素废物，并探讨从这个过程中回收能源的可能性。对木屑和鸡粪进行了特性分析，以确定其热参数、组成性质和热值。还对鸡粪气化得到的主要产物，即生物煤气、生物油和炭进行了分析，以确定它们作为能源的潜力。实验方案包括弹式量热法、热重分析（TGA）、差示扫描量热法（DSC）、傅里叶变换红外（FT-IR）光谱法、拉曼光谱法、元素分析、X 射线衍射（XRD）、矿物含量分析和气相色谱法。还估算了气化装置的质量和能量平衡。研究结果证实，气化是一种可行的鸡粪处理方法。此外，还可以从这个过程中回收一些能源。然而，气相中的能量含量相对较低。这可能是由于气化装置的能量效率（19.6%）较低，可以通过改变操作参数来提高。
