Increased energy demand worldwide has caused faster depletion of sweet feedstock and
increased exploitation of sourer hydrocarbon fuels. These fuels often contain acid gases (H …

We present new explicit representations with temperature and pressure as independent
variables for the Gibbs free energy and entropy of S 2. The developed representations only …

Hydrogen sulfide oxidation experiments were conducted in O2/N2 at high pressure (30 and
100 bar) under oxidizing and stoichiometric conditions. Temperatures ranged from 450 to …

Hydrogen sulfide combustion has been of interest in recent years due to its presence in coal-
derived syngas and in sour gas. However, there are limited data available for the calibration …

Present methods mainly adopt air as an oxidizer for recovering sulfur from lean acid gas, the
presence of N 2 is detrimental to the combustion of lean acid gas. In this study, oxy-fuel …

This contribution combines results of experiments with kinetic modelling to probe the
unusual behaviour of carbonyl sulfide (COS), a sulfur species that frequently arises in fuel …

CO 2 is an important component in the acid gas and it is necessary to study the effect of CO
2 presence on the oxy-fuel combustion of H 2 S with particular focus on the formation of …

This paper presents a detailed kinetic study of H 2 S oxidation with presence of CO 2 under
fuel rich condition. Effect of CO 2 reactivity on the partial oxidation of H 2 S was particularly …

Experimental results are presented on the combustion of H 2 S and mixtures of H 2 S and
xylene at an equivalence ratio of three (Claus condition). The H 2 S mole fraction decreased …

This paper shows the potential for valuable syngas (H 2 and CO) production from a
laboratory-scale reactor, as an alternative and viable means for the treatment of acid gas (H …
