The possibility to apply the hydrothermal carbonization (HTC) process to off-specification compost (EWC 19.05.03) at present landfilled was investigated in this work. The aim was to produce a carbonaceous solid fuel for energy valorization, with the perspective of using HTC as a complementary technology to common organic waste treatments. Thus, samples of EWC 19.05.03 produced by a composting plant were processed through HTC in a batch reactor. Analytical activities allowed to characterize the HTC products and their yields. The hydrochar was characterized in terms of heating value, thermal stability and C, H, O, N, S and ash content. The liquid phase was characterized in terms of total organic carbon and mineral content. The composition of the gas phase was measured. Results show that the produced hydrochar has a great potentiality for use as solid fuel.
本研究考察了应用水热碳化(HTC)工艺处理目前填埋的不合格堆肥(EWC 19.05.03)的可能性。目的是生产一种用于能源增值的碳素固体燃料,并期望将 HTC 作为普通有机废物处理的补充技术。因此,采用批式反应器对堆肥厂生产的 EWC 19.05.03 样品进行 HTC 处理。分析活动允许对 HTC 产品及其产率进行表征。通过热值、热稳定性以及 C、H、O、N、S 和灰分含量来对水热炭进行表征。通过总有机碳和矿物质含量来对液相进行表征。对气相的组成进行了测量。结果表明,所生产的水热炭具有作为固体燃料的巨大潜力。
