Multi-stage extraction process to produce enhanced biocrude from solid waste liquefaction
This study explores the effects of hydrothermal liquefaction temperature and multi-stage extraction method on product quality, yield, and underlying reaction mechanisms using organic solid waste feedstock. Hydrothermal liquefaction experiments are conducted at five temperatures ranging from 250 to 350 °C, and product compositions are characterised using thermogravimetric analysis, gas chromatography-mass spectrometry, and elemental analysis. The results demonstrate that the highest biocrude yield of 30–32 % is achieved within the 300–350 °C range, while multi-stage extraction produced biocrude with a higher heating value of 40–43.7 MJ/kg. The multi-stage extraction method enhances the quality of biocrude by separating most of the nitrogen and oxygen heterocyclic compounds and producing biocrude containing 67–70 % lighter fraction. The Hydrothermal liquefaction temperature of 350 °C promotes decarboxylation and deoxygenation reactions, resulting in lower amounts of carboxylic acids in biocrude, which are suitable for fuel applications. The energy feasibility of the extraction is evaluated by a high energy recovery of 70.4 % with a low energy consumption ratio of 0.26, demonstrating the process's net energy gain and sustainability.
期刊介绍:
The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
