Multiphase flow and chemical reactor thermodynamics for hydrolysis and thermochemical production
… fuels. The copper-chlorine cycle is a promising thermochemical process which can cost-effectively produce hydrogen with less environmental impact. In this thesis, new predictive formulations and experimental data are presented to improve the conversion extent and reaction rates of the hydrolysis …

Application Of Method Developed For The Identification And Quantification Of Polar Components In Organic Liquid Products Of Selected Crop Oils And Deciphering The Mechanistic Aspects Of Cracking
<p>Pyrolysis is a fundamental thermochemical process that can be used to convert triacylglycerides (TGs) in crop oils into valuable chemicals that may replace petroleum products. Biofuels, complex mixtures containing hundreds of species, are generated by the pyrolysis of crop oils. Presence of …

Simulations and modeling of biomass gasification processes
… An Aspen Plus® model was developed for the Thermochemical Process Development Unit (gasification unit) at the National Renewable Energy Laboratory. The model was designed for a feed of poultry litter and was also run with a feed of wood. The Aspen Plus® model is capable of trying various …

Analysis and Treatment of Emerging Polar Contaminants
… compounds survive current wastewater treatment processes. High production volume chemicals (HPVCs), defined as chemicals produced in excess of one million pounds per year have numerous entries into surface and drinking waters due to their ubiquity. The commonality between many of these compounds …

Hydrothermal liquefaction of microalgae: Influence of varying cell compositions on biocrude yield and quality
… feedstock. Hydrothermal Liquefaction (HTL) is a thermochemical process that uses water as the reaction medium to convert biomass into biocrude oil under elevated temperatures and pressures (200–350°C, 5–20 MPa). While there is extensive literature on the separate processes of microalgae …

Hydrothermal Liquefaction of Plastic as an Alternative Recycling Method
… becomes increasingly urgent. HTL is a thermochemical process that decomposes plastics feedstocks using water as a medium under near-critical conditions to produce valuable liquid products. This work aims to investigate the valorisation of plastic waste using HTL, both as an isolated …

Hydrothermal liquefaction for energy recovery from high-moisture waste biomass
… compared against slow pyrolysis, an alternative thermochemical process. Biocrude oil chemistries from both processes were then evaluated against Illinois shale oil as a representative low-quality petroleum crude oil. While both thermochemical conversion routes produced energy dense biocrude oil …
