Northeast India has a good deposit of sub-bituminous tertiary coal. The northeast Indian
coals have unusual physico-chemical characteristics such as high sulfur, volatile matter and …

In this paper, a series of modern advanced analysis and measurement technologies such as
X-ray Fluorescence (XRF), X-ray Diffraction (XRD), 13 C Nuclear Magnetic Resonance (13 …

Thermal dissolution (TD) of coals has advantages, such as milder conditions, simpler
process, and no consumption of catalyst and gaseous hydrogen, over coal …

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 …

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 …

This paper describes a simple oxidative method of desulphurisation of coal organic sulphur
carried out by using hydrogen peroxide as an oxidant. Desulphurisation achieved up to the …

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 …

A systematic study has been made on the desulphurisation of organic sulphur in both feed
and mercury-treated coal for their unoxidised samples as well as their oxidised samples …

Ionic liquid-assisted coal water slurry (CWS) electrolysis was carried out in KNO 3 system
with constant current. The effects of ionic liquids including structure, concentration …

The effect of tourmalines, Na-bentonite and medical stone on the retention of total sulfur,
pyritic sulfur, sulfate sulfur and organic sulfur were investigated in a fixed bed reactor. The …
