Farm and animal wastes are increasingly being investigated for thermochemical conversion, such as gasification, due to the urgent necessity of finding new waste treatment options. We report on an investigation of the use of a farm-scale, auto-thermal gasification system for the production of a heating gas using poultry litter (PL) as a feedstock. The gasification process was robust and reliable. The PL's ash melting temperature was 639°C, therefore the reactor temperature was kept around this value. As a result of the low reactor temperature the process performance parameters were low, with a cold gas efficiency (CGE) of 0.26 and a carbon conversion efficiency (CCE) of 0.44. The calorific value of the clean product gas was 3.39 MJ m(-3)N (LHV). The tar was collected as an emulsion containing 87 wt.% water and the extracted organic compounds were identified. The residual char exceeds thresholds for Zn and Cu to obtain European biochar certification; however, has potential to be classified as a pyrogenic carbonaceous material (PCM), which resembles a high nutrient biochar.
农场和动物废物由于迫切需要寻找新的废物处理选择，因此越来越多地被用于热化学转化，例如气化。我们报告了一项使用农场规模的自热气化系统使用家禽垃圾（PL）作为原料生产加热气体的研究。气化过程稳定可靠。PL 的灰熔融温度为 639°C，因此反应器温度保持在该值附近。由于反应器温度低，工艺性能参数较低，冷气体效率（CGE）为 0.26，碳转化率效率（CCE）为 0.44。清洁产品气体的热值为 3.39 MJ m(-3)N（低位热值）。焦油被收集为含有 87wt.%水的乳液，并且提取了有机化合物。残留的炭超过了获得欧洲生物炭认证的 Zn 和 Cu 阈值；然而，它具有被归类为热解炭质材料（PCM）的潜力，类似于高营养生物炭。
