Journal ArticleDOI
Char gasification in mixtures of CO2 and H2O: Competition and inhibition
TL;DR: In this article, the authors present data generated for the reaction of coal chars with mixtures of CO2 and H2O at high pressures, to determine how existing pure-gas rate data can be applied to more realistic gasification systems.
Journal ArticleDOI
CO2 and steam-gasification in a high-pressure wire-mesh reactor: the reactivity of Daw Mill coal and combustion reactivity of its chars
TL;DR: In this article, the authors examined the relationship between coal gasification, char gasification and combustion reactivities as a function of CO2 and steam pressure and holding time, and found that secondary char deposition caused by tar re-polymerisation plays an increasingly significant effect with increasing particle size.
Journal ArticleDOI
Coal Gasification in CO2 and Steam: Development of a Steam Injection Facility for High-Pressure Wire-Mesh Reactors
TL;DR: In this paper, the development of a steam injection facility and a new control system for steam gasification experiments in a high-pressure wire-mesh reactor have been described, based on preheating the steam path to prevent condensation during experiments.
Journal ArticleDOI
Role of the Epoxy Group in the Heterogeneous CO2 Evolution in Carbon Oxidation Reactions
Astrid Sanchez,Fanor Mondragón +1 more
TL;DR: In this paper, a density functional theory study was carried out to evaluate different possibilities of heterogeneous CO2 desorption in combustion/gasification reactions, and it was found that the peroxy complex can evolve as CO2 with an activation energy of 48 kcal/mol.
Journal ArticleDOI
Thermodynamic evaluation of steam gasification mechanisms of carbonaceous materials
TL;DR: In this paper, it was shown that H 2 O can dissociatively chemisorb through highly exothermic reactions on the active sites of clean zigzag and armchair carbonaceous models.
