    摘要： A process is presented for the reduction of nitrogen oxides in the effluent from the combustion of a carbonaceous fuel. The process comprises introducing a treatment agent comprising a compound selected from the group consisting of five or six-membered heterocyclic hydrocarbons having at least on cyclic nitrogen into an effluent under conditions effective to reduce the concentration of nitrogen oxides in the effluent.

    摘要： A flow-through concrete edge forming system utilizes a body member that has perforations thereon. The body member is placed at an elevation transition area of a monolithic slab as an edge forming form. Once the slab is poured, a parge coating is placed on the outer surface of the body member such that the parge coating either binds to the outer surface or penetrates the body member through a series of perforations on the body member in order for the parge coating to bind with the concrete of the slab which has yet to set thereby producing a clean and solid finish of the outer surface of the slab at the transition area. The body member may have either a rectangular profile, a keyhole profile or may have the perforations on a series of inwardly directed deformations.

    摘要： A process for the reduction of nitrogen oxides in an effluent from the combustion of a carbonaceous fuel while minimizing the production of other pollutants is presented. The process comprises introducing a nitrogen oxides reducing treatment agent comprising an ammonium salt of an organic acid having a carbon to nitrogen ratio of greater than 1:1 into an effluent according to a nitrogen oxides reducing treatment regimen under condition such that the treatment agent is operating on the high temperature or right side of its nitrogen oxides reduction versus effluent temperature curve, especially on the high temperature or right side of the curve plateau.
