| 20120174830 | METHOD OF OPERATING A COAL BURNING FACILITY - Methods involve adding sorbent components, such as calcium oxide, alumina, and silica, as well as optional halogens as part of environmental control. Use of the sorbents leads to significant reductions in sulfur and mercury emissions that otherwise would result from burning coal. Use of the sorbents leads to production of waste coal ash that, while higher in mercury; is nevertheless usable as a commercial product because the mercury in the ash is non-leaching and because the coal ash has a higher cementitious nature by virtue of the increased content of the sorbent components in the ash. Thus, the methods involve adding powders having qualities that lead to the production of a cementitious coal ash while at the same time reducing emissions from a coal burning facility. | 07-12-2012 |
| 20120272877 | Reducing Mercury Emissions From The Burning Of Coal - Sorbent components containing halogen, calcium, alumina, and silica are used in combination during coal combustion to produce environmental benefits. Sorbents such as calcium bromide are added to the coal ahead of combustion and other components are added into the flame or downstream of the flame, preferably at minimum temperatures to assure complete formation of the refractory structures that result in various advantages of the methods. When used together, the components

| 20130074745 | SORBENTS FOR COAL COMBUSTION - Sorbent compositions containing halogen and calcium are added to coal to mitigate the release of sulfur and/or other harmful elements, including mercury, into the environment during combustion of coal containing natural levels of mercury. | 03-28-2013 |
| 20130312646 | REDUCING MERCURY EMISSIONS FROM THE BURNING OF COAL - Sorbent components containing halogen, calcium, alumina, and silica are used in combination during coal combustion to produce environmental benefits. Sorbents such as calcium bromide are added to the coal ahead of combustion and other components are added into the flame or downstream of the flame, preferably at minimum temperatures to assure complete formation of the refractory structures that result in various advantages of the methods.

| 20140020608 | SORBENTS FOR COAL COMBUSTION - Sorbent compositions containing halogen and calcium are added to coal to mitigate the release of sulfur and/or other harmful elements, including mercury, into the environment during combustion of coal containing natural levels of mercury. | 01-23-2014 |
| 20140053760 | REDUCING SULFUR GAS EMISSIONS RESULTING FROM THE BURNING OF CARBONACEOUS FUELS - A method of reducing sulfur emissions by applying remediation materials in a powder sorbent onto coal and combusting the coal with the materials applied. The powder sorbent contain sources of silicon, aluminum, calcium, iron, and magnesium, and ash from combustion contains the captured sulfur. | 02-27-2014 |
