Abstract: Metal sorbent compositions for removing a metal contaminant from a fluid, such as removal of mercury from a coal-fired flue gas stream, and methods for making and using the same are provided. The subject metal sorbent compositions comprise an effective amount of an aqueous dispersion of microfine elemental sulfur particles on an adsorbent substrate, and optionally, a metal capture enhancing agent such as a halogen source and/or an oxidizing agent in an amount providing a metal capture enhancing effect on the metal sorbent composition. The subject metal sorbent compositions are prepared by drying an aqueous dispersion of microfine elemental sulfur particles on an adsorbent substrate, such as on a substrate of microfine particles of a refractory material and the like. Also provided are kits for use in preparing the subject compositions, and compositions produced by the methods. The subject compositions, kits and systems find use in a variety of different applications.

Abstract: A metal article is protected from corrosion under prolonged exposure to normal ambient atmospheric conditions which cause such corrosion by coating the metal article with an adherent organic coating which does not exude corrosive acid, which comprises an effective amount of an aromatic amine compound containing a p-phenylenediamine moiety which is not an epoxy crosslinking agent but which is capable of being oxidized in air, an air oxidation product thereof, or a mixture of the amine and air oxidation product for corrosion protection of the metal article, before the coated metal article is placed in contact with such atmospheric conditions which cause such corrosion.

Abstract: A finely divided metal oxide powdery composition, preferably with a narrow particle size distribution, is produced from a particulate, sol-gel derived composition containing agglomerates by heating the particulate composition in the presence of an effective amount of a composition which decomposes upon heating and forms a gas to break at least a portion of the agglomerates so as to yield the desired finely divided ceramic particle composition. Examples of suitable gas-forming agents for use in the present invention include the ammonium salts or amides of organic and inorganic acids, volatile acids, and gases dissolved in a suitable solvent, such as water, alcohol or ammonia.

Abstract: A solid phosphorus pentoxide containing material suitable for use in fast-setting cements can be produced by a process which comprises mixing a porous material with a liquid, phosphorus pentoxide containing material and heating the mixture until a dry solid is produced.The solid phosphorus pentoxide containing material thus formed can then be dry blended with a solid component comprising magnesium oxide, magnesium hydroxide, magnesium carbonate or mixtures thereof. An aggregate can optionally be added into this dry blend.The components of the resulting dry blend react in the presence of an aqueous component to form a monolithic solid.

Abstract: The invention is a method of treating the distillation residue from the production of phosphorochloridothionates which comprises draining the residue into agitated cold water to form a slurry and contacting the slurry with chlorine gas in a hydrolyzing zone to decompose the residue and produce decomposition gases in controllable amounts having a decreased sulfur content.The novel method would reduce the amount of sulfur in the decomposition gas and make possible the use of less costly abatement facilities.
