A STUDY ON MERCURY AND SULFUR RELEASING CHARACTERS DURING MILD THERMAL UPGRADING
Introduction Over the past few years, extensive efforts have been made to evaluate the quantity of mercury emitted from different sources and to reduce mercury pollution from coal. However, at present, there is no universally accepted mercury control technology for coal-fired utilities. One possible method of reducing mercury emission from coal utilization could be cleaning the coal prior to its utilization.1,2Mild thermal upgrading was a viable option for mercury removal before coal combustion. Some researchers have already done some work using this method2,3. The efficiency of this method for reducing mercury content in coal prior to its combustion depends upon the association of this element with coal components and also the characteristics of the coal. To make deep understanding of mercury removal though mild thermal upgrading, we have to understand the mechanism of mercury releasing and also the affecting factors during this process. Many studies have shown that mercury was associated with sulfide minerals in coal especially for the high-sulfur containing coals. For this reason, the releasing characters of sulfur during mild thermal upgrading should also be studied for better understanding the mercury removal during this process.
