The ease and simplicity of applying the anaerobic digestion technology in the generation of cheap bioenergy has led to its global acceptance as a viable technique for simultaneous value extraction from high moisture containing waste biomass and organic waste management. Crucially, however, the widespread application of anaerobic digestion technologies results in the associated generation of large masses of raw biogas digestate, leading to unintended digestate management challenges. A previous study subsequently investigated the utilisation of the digestate as a sustainable feedstock for bioproduct generation via the incorporation of the hydrothermal liquefaction (HTL) technology. As a sequel to the aforementioned study, the present work sought to investigate the characteristic properties of the major products of the hydrothermal liquefaction processing of anaerobic digestate while simultaneously proposing viable and practical uses of these products. Several characterisation techniques such as nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, inductively coupled plasma mass spectrometry and gas chromatograph-mass spectrometry were applied with representative HTL products from digestate employed in this regard.

在产生廉价的生物能源中应用厌氧消化技术的简便性和简便性，使其在全球范围内成为一种可行的技术，可同时从高水分含量的废物生物质和有机废物管理中提取价值。然而，至关重要的是，厌氧消化技术的广泛应用导致产生大量的原始沼气消化物，从而带来了意想不到的消化物管理挑战。随后的一项先前研究研究了通过将水热液化（HTL）技术并入而将消化液用作生物产品生产的可持续原料。作为上述研究的续篇，本工作旨在研究厌氧消化液水热液化工艺主要产品的特性，同时提出这些产品的可行性和实用性。几种表征技术，如核磁共振波谱，傅立叶变换红外光谱，电感耦合等离子体质谱和气相色谱-质谱联用，均采用了从这方面消化得到的代表性HTL产物。
