A method of generating a de-sulphurized volatile matter and a relatively low Btu gas includes the initial step of pyrolyzing coal to produce volatile matter and a char. The volatile matter is fed to a first de-sulphurizer containing a de-sulphurizing agent to remove sulphur therefrom. At the same time, the char is gasified to produce a relatively low Btu gas. The low Btu gas is fed to a second de-sulphurizer containing the de-sulphurizing agent to remove sulphur therefrom. A regenerator is provided for removing sulphur from the de-sulphurizing agent. Portions of the de-sulphurizing agent are moved among the first de-sulphurizer, the second de-sulphurizer, and the regenerator such that the regenerator regenerates the de-sulphurizing agent. Preferably, the portions of the de-sulphurizing agent are moved from the second de-sulphurizer to the first de-sulphurizer, from the first de-sulphurizer to the regenerator, and from the regenerator to the second de-sulphurizer.
