The main aim of this work is experimental and numerical study of heat and mass transfer in fixed beds by the Joule heating effect, which is a volume-based type of heating rather than surface-based. This is aimed at looking more into energy storage technologies where electrical energy is stored as...

To address the growing concern of environmental sustainability and waste management, recent research efforts have been dedicated to investigating innovative methods for the treatment and conversion of biodegradable disposables and bioplastics. These studies delve into the potential of high solid...

The fragmentation of large coal particles at high temperature is important to the efficient operation of Corex process of steelmaking, which uses raw coal instead of coke. The hypothesis is that the heterogeneity within coal particles affects the fragmentation. The interface of minerals and coal...

Given the volume of sewage sludge produced worldwide, efficient waste management and energy recovery techniques are essential. Anaerobic digestion (AD) and hydrothermal liquefaction (HTL) are viable avenues for the valorization of sewage sludge. Their combination produces a synergistic framework...

This study describes the evaluation of the mixed metal non-supported and supported ion exchanged sorbents for hot gas desulfurization capable of withstanding a wide temperature range and multiple sulfidation-regeneration cycles. Copper-cobalt, copper-cerium mixed metal oxide and mixed metal oxide...

Modelling of solvent extraction was studied using 1,2,3,4–tetrahydronaphtalene (tetralin) and Poplar coal (lignite). A kinetic model was developed taking into account temperature, mass transfer limitations and dominating events (physical or chemical) during coal liquefaction. It was found there...

The oxidative denitrogenation of quinoline (as a model compound representing the nitrogen containing structure of coal liquids) has been investigated in two steps: oxidation by perdecanoic acid at 50 ˚C to produce quinoline N-oxide in order to weaken the nitrogen-carbon bond; thermal...

Solvent deasphalting, followed by asphaltenes gasification, has been recommended as a favorable alternative to coker based upgrading processes. However, very limited work has been carried out on pyrolysis and gasification of asphaltenes, at entrained flow conditions. The present work aims at...
