    摘要： A system for the abatement of industrial process gases utilizes a rotary regenerative oxidizer comprised of one or more heat exchange beds, each bed comprised of a parallel, axial, and longitudinal array of heat regenerative channels that thermally and/or catalytically oxidize contaminated gases. Utilizing a rotary regenerative oxidizer, and if desired, a plurality of heat regenerative beds incorporated therein, facilitates the use of regenerative technology at lower gas flow rates, increases thermal efficiency, and significantly reduces the floor space normally required when implementing fixed-bed nonrotary regenerative oxidizers. The heat exchange channels may be catalytically treated to enhance oxidation of the pollutants at a lower temperature.

    摘要： A method and device for treating a gas stream comprising at least one non-halogenated carbonaceous compound and optionally at least one halogenated organic compound. The gas stream, at 100.degree. C. to 650.degree. C. and in the presence of oxygen is contacted with a first catalyst in a first catalyst zone. The first catalyst comprises a first catalytic material deposited on a low acidity support material. In this zone, the non-halogenated compound is selectively reacted to form innocuous materials such as water and carbon monoxide. This can be followed by contacting the gas stream with a second catalyst in a second catalyst zone. The second catalyst comprises a second catalytic material deposited on a high acidity support material. In this zone, the halogenated organic compounds are reacted.

    摘要： The present invention is directed to an iron-promoted zeolite beta catalyst useful in the selective catalytic reduction of nitrogen oxides with ammonia in which the iron-promoted zeolite beta is treated so as to provide increased amounts of the iron promoter in the form of Fe(OH).The stabilized zeolite is formed by cation exchange of an iron salt into a zeolite beta which has a reduced sodium content such as by exchanging a sodium beta with ammonium or hydrogen cations. A zeolite beta having a reduced carbon content and a Si/Al ratio of no more than 10 also increases the Fe(OH) content of the iron-promoted catalyst. The iron-promoted catalyst which has the iron in the form of Fe(OH) is characterized by a peak at 3680±5 cm−1 in the IR spectra.
