Abstract
A method for desulfurization and dezincification of high-sulfur coal includes the steps of passing tap water into a high oxidation reduction electrocatalytic water equipment to reduce the pH value to 1-2, mixing the pH value 1-2 acid electrocatalytic water thus obtained with the high-sulfur coal, and heating the mixture to let H+ in the acid electrocatalytic water be reacted with sulfur and nitrogen in the high-sulfur coal to cause generation of hydrogen sulfide gas and ammonia where the volatilization of water vapor effectively removes the sulfur and nitrogen in the high-sulfur coal and the hydrogen sulfide and ammonia gases thus generated are collected.
