Disclosed herein are monolith oxidation catalysts for the destruction of CO and volatile organic compounds (VOC) chemical emissions, in particular, the destruction of light alkane organic compounds. The catalysts contain high surface area refractory oxides of silica- and hafnia-doped zirconia and silica, or tin oxide or stabilized alumina; and at least one platinum group metals, in particular platinum metal, or a combination of platinum and palladium.

Oxidation catalysts for destructing VOCs which contain light alkane compounds in emissions

The current embodiments relate to ruthenium-containing supported catalysts, including processes for their manufacture and use, which destroy, through catalytic oxidation, hazardous compounds contained in chemical industrial emissions and otherwise produced from industrial processes.

Low cost oxidation catalysts for VOC and halogenated VOC emission control

An oxidation catalyst deposited on a substrate is described for the destruction of CO and volatile organic compounds, in particular halogenated organic compounds, from an emissions stream at temperatures from 250&#xb0; C. to 450&#xb0; C. The oxidation catalyst includes at least two platinum group metals, one of which is either platinum or ruthenium, supported on refractory oxides, such as a solid solution of CeOand ZrO, and tin oxide and/or silica.

Oxidation catalyst and method for destruction of CO, VOC and halogenated VOC

An oxidation catalyst deposited on a filter substrate for the removal of CO, hydrocarbons, and particulate matter, such as soot, from an exhaust stream wherein the oxidation catalyst is formed from a platinum group metal supported on a refractory oxide, tin oxide, and a zeolite.

Oxidation catalyst on a substrate utilized for the purification of exhaust gases

A diesel oxidation catalyst comprising a honeycomb substrate washcoated with a mixture of clay, a refractory oxide and a zeolite is disclosed. The washcoated substrate is subsequently deposited with a precious metal catalyst and a sulfur oxidation suppressant. In a preferred embodiment, the clay is acid-leached bentonite, the refractory oxide is zirconia or titania, the zeolite is beta-zeolite or Y-zeolite or ZSM-5 or mordenite, the precious metal catalyst is preferably platinum, and the sulfur oxidation suppressant is vanadium or vanadium oxide or a combination thereof

Catalyst for purifying diesel engine exhaust emissions

A catalyzed diesel particulate matter exhaust filter with improved diesel particulate matter oxidation activity and thermal stability including a porous filter substrate for filtering the diesel particulate matter washcoated with high surface area support alumina, titania, silica and zirconia promoted with one of ceria, lanthanum oxide, tungsten oxide, molybdem oxide, tin oxide for catalytic materials which includes an alkaline earth metal vanadate, and a precious metal

Catalyzed diesel particulate matter filter with improved thermal stability

A catalyzed diesel particulate matter exhaust filter including a porous filter substrate for filtering the diesel particulate matter impregnated with a catalytic material which includes an alkaline earth metal vanadate and a precious metal.
