The most important commercial outlet for coal ash is in the concrete industry as a partial replacement for Portland cement. In many concrete mixtures careful control of air entrainment is required, but the presence of solid carbon disrupts the air entrainment process. An earlier study focused on the fundamental role of carbons, which were found to adsorb airentraining admixtures, the ...
high lossonignition (LOI) fly ash can transform this combustion byproduct from a waste material, wit h associated disposal costs, to a valuable product. The utilization of powerplantderived fly ash has bee n impacted by recent shifts to lowNO x burners which can increase the carbon content of the ash above th e
title = "Physical cleaning of high carbon fly ash", abstract = "An industrial fly ash sample was cleaned by three different processes, which were triboelectrostatic separation, ultrasonic column agglomeration, and column flotation.

A novel CO2 absorbent, MgOZrO2 nanocomposite was synthesized via appropriate solgel process. The structure and surface properties of the asprepared materials were characterized by XRD, N2 adsorptiondesorption and CO2TPD techniques. It was found the asprepared materials showed high thermal stability, and their mesoporous framework was well preserved even after calcinations at 700oC.
Analysis of surface deposits by scanning electron micrograph show a high content of sulfate compounds specifically calcium sulfates well above the content usually observed in fly ash. It is theorized that sulfuric acid (from high SOs) condensed on the fly ash, .
Red mud is disposed as slurry having a high solid concentration of 3060% and with a high ionic strength. It is disposed as dry or semi dry material in red mud pond or abandoned bauxite mines. The disposal of the red mud represents a major loss of valuable soda and has a high pH value as a result of the entrained soda.

These CCBs mainly consist of fly ash with high lossonignition (LOI) carbon concentrates produced by the lower combustion temperatures required for the operation of the lowNO x burners. Due to the limited applications of these high carbon fly ashes, they are being placed in landfills, which is also detrimental to the environment.

The International Ash Utilization Symposia are a series of biennial symposia covering all aspects of coal combustion byproduct utilization. These symposia provide a forum for the transfer of information and new ideas to benefit the innovative utilization, handling, storage and disposal of CCBs. The symposia are organized by the Center for Applied Energy Research at the University of Kentucky.

A process for simultaneous removal of and from a gas stream that includes flowing the gas stream to a spray dryer and absorbing a portion of the content of the gas stream and a portion of the content of the gas stream with ZnO by contacting the gas stream with a spray of an aqueous ZnO slurry; controlling the gas outlet temperature of the spray dryer to ...
A study of carbon concentrates separated by a number of different commercial and laboratory methods from various coalcombustion fly ashes was undertaken to determine what common and unique chemical and physical properties can be expected in such concentrates. The properties were determined using a variety of physical and spectroscopic characterization methods and then were compared among the ...
