The iron and steel making is considered among the biggest industries which run the world.
This industry contributes around 20% of global industrial-sector energy consumption that is …

Coal desulfurization prior to combustion, coking or gasification is beneficial for both the
upgrading of quality of commercial coal and the protection of the environment. The sulfur in …

This paper presents a neural network model to predict the effects of operational parameters
on the organic and inorganic sulfur removal from coal by sodium butoxide. The coal particle …

Organic sulfur functional groups in coal not only have certain oxidation characteristics at low
temperature and but also can break to produce free radicals, which is bound to have a …

The north eastern region (NER) of India has a substantial deposit of high sulfur (2− 8%)
coals with low ash and high volatile matter contents. Assam, one of the coal producing states …

Tabas coal sample from Iran was desulfurized with combination of microwave irradiation
and peroxyacetic acid washing in a batch reactor. The effect of irradiation time and power …

The structure and distribution of organic sulfur in coals of different rank and different sulfur
content were studied by combining mild organic solvent extraction with XPS technology. The …

Spontaneous combustion of coal is a phenomenon that often occurs in open coal mining
activities, especially strip mining and open pit mining systems which are detrimental to …

This paper selects two typical compounds containing organic sulfur as model compounds.
Then, by analyzing the chromatograms of gaseous low-temp oxidation products and GC/MS …

Research on the spontaneous combustion of coal caused by sulfur has always been
focused on pyrite in coal but has rarely considered the influence of organic sulfur. In this …
