Abstract

The tests of pre-desulfurization of high-sulfur Chinese coals lower temperature air oxidation method was presented. It aims at reducing sulfur to levels that make coal combustion environmentally acceptable and cost effective. In this process four Chinese coals from Yima, Datong, Xishan, and Yangquan were selected and tested in a fixed-bed. The variables of operational condition included temperature (300-500°C), solid resident time (10-60 min) and particle size (100 μm, 400 μm) in this process. The contents of sulfur and its form, volatile, calorific value, proximate analysis and ultimate analysis were determined before and after the desulfurization process according to Chinese standards. The experimental results showed that the coal types and experimental conditions are important factors in the process.
