Waste management via thermochemical processing is gaining increasing importance as larger volumes of solid waste are generated yearly. The poultry industry generates a variety of wastes, of which the largest stream in terms of volume is the litter. In this study, three thermodynamic models were developed on ASPEN Plus v8.8 for pyrolysis, in‐line steam reforming, and gasification of poultry litter. At optimal pyrolysis of 450 °C, the product yield was 43.74 wt% bio‐oil, 6.71 wt% gas, and 49.55 wt% char. The optimal conditions for the in‐line steam reforming of poultry litter were observed to be 400 °C temperature and 12 kg kg⁻¹ steam‐to‐feed ratio (STFR), yielding a syngas composition of 70.2 mol% H₂, 29.4 mol% CO₂, 0.22 mol% CH₄, and a trace amount of CO. The optimal conditions for the gasification of poultry litter were 700 °C temperature and 0.2 kg kg⁻¹, yielding a syngas composition of 52.6 mol% H₂, 10.3 mol% CO₂, 2.77 mol% CH₄ and 34.3 mol% CO. Gasification gave a higher syngas yield but with less quality. Steam reforming gave better quality but a lower yield. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd

通过热化学处理对家禽垃圾的增值建模

随着每年产生大量固体废物，通过热化学处理进行废物管理变得越来越重要。家禽业产生各种废物，其中废物量最大的是垃圾。在这项研究中，在ASPEN Plus v8.8上开发了三种热力学模型，用于热解，在线蒸汽重整和家禽垃圾的气化。在450°C的最佳热解条件下，产品产率为43.74 wt％的生物油，6.71 wt％的气体和49.55 wt％的炭。观察到的在线蒸汽家禽废弃物的重整的最佳条件为400℃的温度和12公斤公斤^-1蒸汽-进料比率（STFR），产生70.2％（摩尔）H的合成气组合物₂，29.4摩尔％CO ₂，0.22％（摩尔）CH ₄，和的CO。用于家禽垃圾的气化的最佳条件的微量是700℃的温度和0.2kg千克^-1，得到52.6％（摩尔）H的合成气组合物₂，10.3摩尔％CO ₂，2.77％（摩尔）CH ₄和34.3摩尔％的CO。气化产生较高的合成气产率，但是质量较低。蒸汽重整的质量更好，但收率较低。©2019年化学工业协会和John Wiley＆Sons，Ltd
