Abstract: Biomass is quickly becoming an important feedstock for energy generation in power plants. Due to their composition and nature, certain biomass fuels contribute to slagging, fouling, and corrosion. This invention provides a novel method of reducing or suppressing slag deposition and/or cleaning deposited slag in energy production processes in which potassium-containing solid fuels are combusted. Besides acting as a slag suppressant, further advantages of this invention are that the additive has no detrimental side-effects on capital equipment, increases slag friability, decreases slag fouling rate, reduces heat transfer corrosion as well as increasing the lifetime of the selective catalytic reduction catalyst.

Abstract: Methods for facilitating the removal of mercury from flue gases by converting elemental mercury to oxidized mercury and subsequently capturing the oxidized mercury. In one aspect, a method of removing mercury from a mercury-containing flue gas may include the steps of introducing into the flue gas a sulfide source in an effective amount to convert elemental mercury to gaseous oxidized mercury and then capturing the gaseous oxidized mercury.

Abstract: Methods for controlling mercury emissions and/or reducing corrosion of equipment used in combustion processes are provided, and more particularly, methods for controlling mercury re-emissions from a wet flue gas desulfurizer and/or reducing corrosion of the wet flue gas desulfurizer.

Abstract: A catalyst support which may be used to support various catalysts for use in reactions for hydrogenation of carbon dioxide including a catalyst support material and an active material capable of catalyzing a reverse water-gas shift (RWGS) reaction associated with the catalyst support material. A catalyst for hydrogenation of carbon dioxide may be supported on the catalyst support. A method for making a catalyst for use in hydrogenation of carbon dioxide including application of an active material capable of catalyzing a reverse water-gas shift (RWGS) reaction to a catalyst support material, the coated catalyst support material is optionally calcined, and a catalyst for the hydrogenation of carbon dioxide is deposited on the coated catalyst support material. A process for hydrogenation of carbon dioxide and for making syngas comprising a hydrocarbon, esp. methane, reforming step and a RWGS step which employs the catalyst composition of the present invention and products thereof.

Abstract: Disclosed are methods for controlling, mercury emissions, and more particularly, to methods for controlling mercury re-emissions from a wet flue gas desulfurizer used in a combustion process. A method of controlling mercury re-emission from a combustion process includes measuring either mercury concentration, oxidation-reduction, potential (ORP), and/or sulfide concentration within a scrubber liquor of a wet flue gas desulpherizer (wFGD); correlating the mercury concentration, ORP, and /or sulfide concentration with an amount of mercury re-emission additive required in the scrubber liquor to reduce and/or prevent mercury re-emission to a selected level; and adjusting the rate of addition of mercury re-emission additive into the scrubber liquor to attain the selected level of mercury re-emission.
