Zeolite catalysts and systems and methods for preparing and using zeolite catalysts having the CHA crystal structure are disclosed. The catalysts can be used to remove nitrogen oxides from a gaseous medium across a broad temperature range and exhibit hydrothermal stable at high reaction temperatures. The zeolite catalysts include a zeolite carrier having a silica to alumina ratio from about 15:1 to about 256:1 and a copper to alumina ratio from about 0.25:1 to about 1:1.

Copper CHA zeolite catalysts

Catalysts comprising metal-loaded non-zeolitic molecular sieves having the CHA crystal structure, including Cu-SAPO-34, and methods for treating exhaust gas incorporating such catalysts are disclosed. The catalysts can be used to remove nitrogen oxides from a gaseous medium across a broad temperature range and exhibit hydrothermal stability at high reaction temperatures.

Methods utilizing non-zeolitic metal-containing molecular sieves having the CHA crystal structure

The present disclosure provides an AgBi catalyst over alumina suitable for performing hydrocarbon selective catalytic reduction (HC-SCR).

[object Object]

The invention relates to a catalyst comprising a monolith composed of a catalytically inert material with low BET surface area and a catalyst layer which has been applied to the monolith and comprises, on an oxidic support material, at least one noble metal selected from the group consisting of the noble metals of group VIII of the Periodic Table of the Elements, optionally tin and/or rhenium, and optionally further metals, wherein the thickness of the catalyst layer is 5 to 500 micrometers.

Monolith catalyst and use thereof

Systems for treating exhaust gas incorporating catalysts comprising metal-loaded non-zeolitic molecular sieves having the CHA crystal structure, including Cu-SAPO-34, and methods for preparing such catalysts are disclosed. The catalysts can be used to remove nitrogen oxides from a gaseous medium across a broad temperature range and exhibit hydrothermal stability at high reaction temperatures.

Described is a metal oxide support material containing nanoscaled iron-platinum group metal particles having a particle size in the range of 0.5 to 10 nm. At least 70% of the nanoscaled iron-platinum group metal particles are located on an outside surface layer of the metal oxide support material. The outside surface layer has an average volume of less than 50% based on the total volume of the metal oxide support material. Additionally, described is a process for preparation of metal oxide support materials containing nanoscaled iron-platinum group metal particles. Furthermore, described is the use of metal oxides containing nanoscaled iron-platinum group metal particles as catalysts, for example as a diesel oxidation catalyst for the treatment of exhaust gas emissions from a diesel engine.

Processes for reducing nitrogen oxides using copper CHA zeolite catalysts

A massive body, e.g., a tablet, for producing a thickened solution of chlorine dioxide when the massive body is added to liquid water is disclosed. The massive body comprises a metal chlorite, an acid source and a thickener (incorporated directly into the massive body or added as a component separate from the massive body) and optionally a source of free halogen. The concentration of free chlorine in the solution will be: (a) less than the concentration of chlorine dioxide in said solution on a weight basis and the ratio of the concentration of chlorine dioxide to the sum of the concentrations of chlorine dioxide and chlorite anion in said solution is at least 0.25:1 by weight; or (b) equal to or greater than the concentration of chlorine dioxide in said solution on a weight basis and the ratio of the concentration of chlorine dioxide to the sum of the concentrations of chlorine dioxide and chlorite anion in said solution is at least 0.50:1 by weight.
