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 prepared at 50, 100 and 150ЊC in air under normal atmospheric pressure. A continuous increase of organic sulphur loss has b

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 extent of 3.70Β±6.25 wt% in 1Β±4 h whereas at 24 h, it increases to 9.24 wt%. When metal ions are externally added to the

Hydropyrolysis (HyPy) of a high-sulphur (4.3 wt% mf) and high-calcite (7.3 wt% mf) subbituminous coal (Sulcis coal) has been studied in a semi-batch fixed-bed reactor under a pressure of 1 or 3 MPa from 580 to 850Β°C. The maximum temperature attained is not necessarily the temperature that the reacto

In this paper, experiments have been undertaken to understand the nature of organic sulphur compounds retained after oxidation at 50,100 and 150ЊC for both feed and Hg-treated coals as well as the extent of desulphurization by the electron transfer process. It has been observed that oxidation of coa
