    Abstract: A stable aqueous suspension of a mixture of magnesium hydroxide and copper oxychloride, together with a suspending agent, is used to reduce deposits in kilns or furnaces used to make iron ore agglomerates, known as pellets, during a calcination process in which iron ore fines mixed with fluxing materials having a phosphate content of less than 1% by weight of the total flux and iron ore weight, are heated to from about 900.degree. to about 1400.degree. C. in order to create the hardened iron ore pellets, called flux pellets, one of the chief raw materials in steel making.

    Abstract: The invention provides compositions to remove mercury and other pollutants from a fluid stream, particularly flue gases containing them. The compositions are mixtures of compounds selected from two or more different groups of compounds. One of the compositions can simultaneously remove mercury and condition the dust for better removal of the dust by an ESP if an ESP is the device of choice for dust control. This composition is a mixture selected from the group of halides other than fluoride and chloride, and mixture thereof, and that selected from a group of nitrates. In the other invention, the composition consists of a mixture of selected polyhydroxy compound or compounds, ammonium sulfate, halides other than fluoride and chloride, and mixture thereof. The composition can be liquid or dry powder and can be injected ahead of the particulate control device as a mist when the formulation is a liquid or as a powder when dry. Methods are provided for applying the formulations.

    Abstract: A process for separating porous components from non-porous components of a mixture of granular materials comprising the steps of:(a) contacting the mixture of the porous and non-porous materials with a gas capable of adsorbing in the pores of the porous component;(b) discharging the so charged or loaded mixture into a liquid in which the adsorbed gas is allowed to desorb from the porous componet, the viscosity and surface tension of the liquid being chosen so that the desorbed gas remains attached to the porous component with the specific gravity of the liquid chosen to separate the so desorbed porous component from the nonporous component; and(c) separating the floating materials from those of sinking materials in the liquid of Step (b).

    Abstract: A carbon supported catalyst used for carbon monoxide oxidation is chemically modified by treating the activated carbon support with an oxidizing agent and/or a hydrophobic compound prior to impregnation with the catalyst mixture. The thus treated catalytic carbon is capable of oxidizing carbon monoxide in an air stream containing sulfur dioxide over an extended period of time.

    Abstract: This provides a method for producing fine particles of liquid or a mixture of liquids that contains dissolved solids in it. This particularly applies to solutions of salts that specially need to be added to gaseous streams at temperatures above ambient. The method can also be applied for producing very fine particles and aerosols of materials that are normally solid or liquid by selecting appropriate solvent, pressure and temperature.
