Colloidal coal-in-water slurries having nano-particles of coal creating a pseudo-fluid. The colloidal coal-in-water slurry generally includes from about fifty to about seventy two weight percent of coal, with about 20 to about 80 percent of the coal having a particle size of about one micron or less with a mode particle size of about 250 nanometers. The coal-in-water slurry can also include a surfactant system containing one surfactant or mixtures of two or more surfactants, or mixtures of one or more surfactants and an inorganic or organic salt. The coal-in-water slurry can be used in low NOx burner applications as the main fuel and/or the reburn fuel, in gasification processes as the input fuel either alone, or in combination with organic materials, in gas turbine applications, and in diesel engine applications.

A process for the in-situ production of an effluent sorbent-oxide aerosol with promoter during the combustion of a hydrocarbon containing fuel whereby the effluents are removed from the resultant gaseous hydrocarbon stream comprises admixing an aqueous solution of the sorbent and promoter with the fuel, atomizing and combusting the mixture under controlled conditions so as to generate the effluent sorbent-oxide aerosol.

Sulfur-sorbent promoter for use in a process for the in-situ production

A process for producing a sulfur sorbent composition in a mixer having a mixer paddle an energy supply is disclosed which includes hydrating an alkaline earth metal oxide in an aqueous solution containing a promoting additive selected from a group consisting of urea and mixtures of urea with a water soluble iron salt under high intensity mixing conditions with the mixer wherein the mixer is operated at a mixer paddle tip velocity of at least 500 ft/min and a mixer energy input of at least 3.5 kW-h per ton of sorbent so as to produce a sulfur sorbent composition having the following physical and chemical properties: alkaline earth metal (wt. %)--40-52, molar ratio of promoting additive to alkaline earth metal--0.001-0.2, bulk density (g/ml)--0.35-0.75, surface area (m.sup.2 /g)--5-25, pore volume (cc/g)--0.05-0.14 and mean particle size (um)--4.

Sorbent for treatment of effluent gas stream

The present invention relates to an improved sorbent for use in removing effluents such as sulfur dioxide from combustion gas streams. The sorbent comprises a hydroxide formed from an alkaline-earth based material such as lime and having incorporated therein an iron and organic compound promotion addition to enhance its ability to remove effluents from the gas stream. The sorbent is formed by co-dissolving an iron salt and an organic compound in a hydration solution and thereafter mixing the hydration solution containing the iron salt and the organic compound with an alkaline-earth based material. The sorbent thus produced may be injected into a gas stream in either dry or slurry form to remove the effluents.
