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 3.70-6.25wt% in 1-4h whereas at 24h, it increases to 9.24wt%. When metal ions are externally added to the system containing coal and hydrogen peroxide, desulphurisation is reduced considerably in the presence...
The viscosity of dilute aqueous solutions of K3[AI(ox)3]·3H2O, K3[Fe(ox)3]·3H2O, K3[Co(ox)3]·3H2O, and K3[Cr(ox)3]·3H2O complexes, as well as K2(ox)·H2O, were measured between 15 and 35°C. Those of CoCl2, 6H2O, FeCl3, A12(SO4)3·18H2O, and CrCl3·6H2O were measured at 25°C. These data were analyzed by the Jones–Dole equation. The ionic B coefficients of the above complex anions were discussed in terms...
