摘要
A process for the desulphurization of low-medium rank coal is described comprising a first step of leaching with potassium hydroxide and a second step of leaching with hydrogen peroxide. Said process allows low-medium rank coal to be desulphurized in an efficient and highly reproducible manner, whereas suitably limiting loss of calorific value, so as to upgrade low-medium rank coal and make economically and environmentally convenient the use thereof.
