In the present study, coal washery reject. which is a solid waste material generated in coal preparation processes, is utilized to prepare carbonaceous sorbents for removal of pollutant gases SO, and NO, from flue gases. The pyrolyzed char is activated with CO\* in order to improve its surface area
The bimolecular reactions in the title were measured behind shock waves by monitoring the 0-atom production in COS-02-Ar and CS2-02-Ar mixtures over the temperature range between 1400 and 2200 K. A value of the rate constant for S + O2 -+ SO f 0 was evaluated to be (3.8 2 0.7) x 10" cm3 mol-' s-' be
