Hydrothermally stable, low-temperature NO.sub.x reduction NH.sub.3-SCR catalyst

Title: Hydrothermally stable, low-temperature NO.sub.x reduction NH.sub.3-SCR catalyst

Abstract

A catalyst composition includes a heterobimetallic zeolite characterized by a chabazite structure loaded with copper ions and at least one trivalent metal ion other than Al.sup.3+. The catalyst composition decreases NO.sub.x emissions in diesel exhaust and is suitable for operation in a catalytic converter.

In-line localized monitoring of catalyst activity in selective catalytic NO.sub.x reduction systems

Patent Muzio, Lawrence J [Laguna Niguel, CA]; Smith, Randall A [Huntington Beach, CA]

Localized catalyst activity in an SCR unit for controlling emissions from a boiler, power plant, or any facility that generates NO.sub.x-containing flue gases is monitored by one or more modules that operate on-line without disrupting the normal operation of the facility. Each module is positioned over a designated lateral area of one of the catalyst beds in the SCR unit, and supplies ammonia, urea, or other suitable reductant to the catalyst in the designated area at a rate that produces an excess of the reductant over NO.sub.x on a molar basis through the designated area.
