Investigation of Vaporization and Devolatilization of Coal/Water Mixtures. First Quarterly Report, April 20, 1982-July 19, 1982

摘要

During the first quarter of this program, the existing entrained flow reator was used to obtain data on an undried Beulah (Zap), North Dakota lignite containing about 30 wt% water. Good material balances have been obtained and the gas analyses by Fourier Transform Infrared Spectroscopy have been compared with the previously developed pyrolysis model. The agreement between experiment and theory is good for those gas species in which reactions with steam can be ignored. This report describes the reactor and the plans to construct a second reactor for use with coal/water slurries. The pyrolysis model is reviewed and modifications to te model to include steam reactions are outlined. (ERA citation 08:013893)
