Abstract
An improved process for producing a formed activated coke for simultaneous desulfurization and denitrification, which includes passing a ground coal through a tubular or cylindrical carbonization retort by using a hot gas stream, to subject the coal to preliminary carbonization to obtain a semi-coke, adding a caking agent to the semi-coke and forming the mixture, subjecting the formed material to carbonization to obtain a formed coke, and transferring the formed coke from the top to the bottom of a vertical multi-tubular retort of indirect heating and cooling (cooling is optional) type that includes a distribution section, a heating section, an activation section and a cooling section (the distribution section and the cooling section are optional) arranged in this order (the distribution section is at the top), to activate the formed coke.
