The influence of a hard coal type on the degree of sulphur dioxide removal

In this paper the authors have studied the properties of zeolite and montmorillonite doped with the nickel and cobalt cations in the removal of SO₂ from the combustion gases process based on the DESONOX method. Burning coal from the hard coal from the Silesian Coal Basin mine "Julian" and the Lubelskie Coal Basin mine "Bogdanka" with supports only - did not show any reduction of the SO₂ emission in the combustion gases.
