Sequential hydrothermal dechlorination and liquefaction of PVC

Energy Conversion and Management
Poly(vinyl chloride) (PVC) is globally the third most produced plastic, but recycling PVC waste through mechanical means is difficult. Due to the high presence of chlorine in PVC, it is unsuitable for both pyrolysis and combustion. Consequently, there is a need to explore innovative methods for harnessing its energy potential. Hydrothermal liquefaction

Characterization of Liquefaction Products from Lignocellulosic and Aquatic Biomass

Biomass
Biomass liquefaction is a promising thermochemical route to convert lignocellulosic residues into bio-oil. This study evaluates the liquefaction behavior of 13 biomasses with varying particle sizes (0.3–2.0 mm) and moisture contents (5–11%) under mild ...

Hydrothermal Liquefaction of Spent K-Cups

Waste and Biomass Valorization
Abstract Hydrothermal liquefaction (HTL) uses high-temperature, high-pressure water to convert plastics, biomass, and their mixtures into a crude heavy oil. Spent K-Cups represent a large, difficult-to-recycle waste stream because they contain biomass (spent coffee grounds, paper), plastics (polypropylene), and ...

Depolymerization of fractionated wood by hydrothermal liquefaction

, 2019
Direct thermochemical conversion of lignocellulosic biomass produces a mixture of compounds that must be separated to produce purified building blocks. Moreover, lignin derived products have a detrimental effect on further biological conversion processes, such as fermentation. For all these reasons, it is important to develop an integrated approach for
