Abstract: The processing conditions for producing the absorptive catalyst from lignite are described. The desurphurization and denitrification test process using absorptive catalyst from lignite are studied. The influence facts of the efficiency of desurphurization and denitrification is discussed. The experiments show that the oxyten concentration, water vapor content, ammonia content and smog temperature can all affect the desurphurization efficiency. On the basis of experiments, the technological conditions are given. The result shows that the absorptive catalyst developed with the main material lignite has good desurphurization and denitrification characteristics.

Key words: absorptive catalyst, desurphurization, denitrification , lignite
