Desulphurization of two Turkish lignites in an entrained flow reactor

Abstract

Desulphurization of Balkaya and Bolu-Mengen lignites by flash pyrolysis in an entrained flow reactor under nitrogen atmosphere was investigated. Experiments were conducted in a 450-750 degrees C temperature range. The change of sulphur types, the removal of total sulphur and volatile matter with pyrolysis temperature were found. The removal of the total sulphur and the volatile matter for Balkaya lignite at 750 degrees C were obtained as 42.2 and 72.7%, respectively, while these values are 57.0 and 66.8% for Bolu-Mengen lignite at the same temperature.
