pulverized coal

The effect of oxidant composition on the oxidative desulfurization of low grade coal has been studied to obtain raw materials for the production of pulverized coal. The experimental-statistical model has been developed that allowed to establish optimum conditions of the investigated process.

The effect of oxidant relative flow rate on the sulfur removal degree and conversion level of coal organic matter has been determined. Sulfur content, as well as ash content and volatiles yield depend on the mentioned values. The optimal oxidant relative flow rate to realize the oxidative desulfurization process has been found with the aim of obtaining raw material for pulverized coal production.
