  <dc:description>&lt;div id="abstractBox" class="article_abstract-content hlFld-Abstract"&gt;&lt;p class="articleBody_abstractText"&gt;Activated chars were produced from Illinois coal and tested in several flue gas cleanup applications. High-activity chars that showed excellent potential for both SO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and NO&lt;i&gt;&lt;sub&gt;x&lt;/sub&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;removal were prepared from an Illinois No. 2 bituminous coal. The SO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(120 °C) and NO&lt;i&gt;&lt;sub&gt;x&lt;/sub&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(25 °C) removal performance of one char compared favorably with that of a commercial activated carbon (Calgon Centaur). The NO&lt;i&gt;&lt;sub&gt;x&lt;/sub&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;removal performance of the same char at 120 °C exceeded that of the Centaur carbon by more than 1 order of magnitude. Novel char preparation methods were developed including oxidation/thermal desorption and hydrogen treatments, which increased and preserved, respectively, the active sites for SO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and NO&lt;i&gt;&lt;sub&gt;x&lt;/sub&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;adsorption. The results of combined SO&lt;sub&gt;2&lt;/sub&gt;/NO&lt;i&gt;&lt;sub&gt;x&lt;/sub&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;removal tests, however, suggest that SO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and NO&lt;i&gt;&lt;sub&gt;x&lt;/sub&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;compete for similar adsorption sites and SO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;seems to be more strongly adsorbed than NO. A low-activity, low-cost char was also developed for cleanup of incinerator flue gas. A three-step method involving coal preoxidation, pyrolysis, and CO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;activation was used to produce the char from Illinois coal. Five hundred pounds of the char was tested on a slipstream of flue gas from a commercial incinerator in Germany. The char was effective in removing &amp;gt;97% of the dioxins and furans present in the flue gas; mercury levels were below detectable limits.&lt;/p&gt;&lt;/div&gt;</dc:description>
