Optimal process design for the polygeneration of SNG, power and heat by hydrothermal gasification of waste biomass: Process optimisation for selected substrates

François Maréchal, Frédéric Vogel, Martin Gassner, Georges Heyen

Based on a previously developed thermo-economic process model, this paper presents a detailed design study for the polygeneration of Synthetic Natural Gas (SNG), power and heat by catalytic hydrothermal gasification of biomass and biomass wastes in supercr ...

Interactions and Reactivity at Liquid-Liquid Interfaces

Manuel Alejandro Méndez Agudelo

The interface between two immiscible electrolyte solutions (ITIES) provides a well-defined platform for fundamental studies of adsorption processes and molecular reactivity in general. Two bio-inspired systems are considered in the present work: adsorbed p ...

Optimal Process Design of Hydrothermal SNG Production from Waste Biomass

François Maréchal, Frédéric Vogel, Martin Gassner

Hydrothermal gasification of biomass in supercritical water is one of the rare pathways that potentially allows for a complete conversion of wet waste biomass into Synthetic Natural Gas (SNG). This paper summarises an extensive process design study and dis ...

The important role of pressure in supercritical fluid process development revealed by reaction calorimetry

Thierry Meyer, Charalampos Mantelis

The technique of reaction calorimetry adapted for use with reactions in supercritical fluids was used to study some safety aspects of the free-radical dispersion polymerization of methyl methacrylate in scCO2. The reaction heat rate profile was found to ch ...

Processing and Mechanical Properties of Novel Wood Fibre Composites Foams

Pierre-Etienne Bourban, Matthieu Cuénoud, Razvan Cristian Neagu

Wood fibre reinforced polylactic acid (PLA) composite foams have been successfully produced using supercritical carbon dioxide. A significant increase of specific properties, both stiffness and strength, was achieved by adding 5-10 wt% wood fibres. The exp ...

On the possibility of extending the Noro-Frenkel generalized law of correspondent states to nonisotropic patchy interactions

Giuseppe Foffi, Francesco Sciortino

Colloidal systems (and protein solutions) are often characterized by attractive interactions whose ranges are much smaller than the particle size. When this is the case and the interaction is spherical, systems obey a generalized law of correspondent state ...

Hydrogen bonding and coordination in normal and supercritical water from x-ray inelastic scattering

Nicola Marzari

A direct measure of hydrogen bonding in water under conditions ranging from the normal state to the supercritical regime is derived from first-principles calculations for the Compton scattering of inelastically scattered x rays. First, we show that a measu ...

Temperature-induced morphology control in the polymer- foaming process

Thierry Meyer, Charalampos Mantelis

Supercritical carbon dioxide (scCO2) is a promising foaming agent for the production of polymeric foams, representing an environmentally friendly alternative for the foaming agents currently used. During the expansion phase of the scCO2-foaming process, te ...
