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

The invention provides a method of synthesizing a zeolite having the CHA crystalline framework, the method including forming a reaction mixture comprising an alumina source comprising a zeolite having an FAU crystalline framework, a silica source, and an organic structure directing agent, the reaction mixture&#x2014;having a combined molar ratio of M/Si+R/Si higher than the molar ratio OH/Si, wherein M is moles of alkali metal and R is moles of organic structure directing agent; and crystallizing the reaction mixture to form a product zeolite having the CHA crystalline framework, wherein the product zeolite has a mesopore surface area (MSA) of less than about 25 m/g. The invention also includes catalyst articles made using the product zeolite, exhaust gas treatment systems including the catalyst articles, and methods of treating exhaust gas using the catalyst articles.

Processes for reducing nitrogen oxides using copper CHA zeolite catalysts

A platy pigment substrate having a carbon-containing coating thereon is provided wherein the coating comprises a pyrolyzed carbon-containing ionic species. The products of the present invention may be used in any application where pearlescent pigments have been used heretofore including but not limited to automotive and industrial paint applications.

Carbon coated high luster materials

The present invention is directed to a novel metal-promoted zeolite catalyst, a method of producing the catalyst and a method of using the catalyst for the selective catalytic reduction of NOwith improved hydrothermal durability. The novel metal-promoted zeolite is formed from a low sodium zeolite and is hydrothermally treated after metal ion-exchange.
