摘要 |
Methods and compositions are provided for treating coal to reduce the emissions of sulphur dioxide and hydrogen chloride gases upon combustion. In the subject method, coal is washed with a calcium anion wash solution, such as calcium hydroxide solution, and then separated from the wash solution. The treated coal exhibits reduced emissions of both sulphur dioxide and hydrogen chloride gas on combustion as compared with untreated coal.
