Desulphurization of some Turkish lignites by pyrolysis

Abstract

Abstract The purpose of this study was to examine the sulphur removal efficiency of pyrolysis from some Turkish lignites. The parameters tested for their effects were: flow of nitrogen; particle size of coal; time and temperature. Temperature is the most important factor and the total sulphur removed increased up to 900 °C. Pyrolysis is effective in removing all three sulphur-containing groups in lignite. The ultimate and proximate analysis of the lignite samples affect the desulphurization yield of pyrolysis and the sulphur content of the products.
