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 filter system for adsorbing contaminants from an exhaust stream from a molten carbonate fuel cell including a filter substrate, a high surface area inorganic adsorbent secured to the filter substrate by an inorganic binder and an inorganic acid secured to the filter substrate. Also disclosed is a process for preparing the filter system for filtering exhaust gas from the molten carbonate fuel cell and a process for using the filtering system in a molten carbonate fuel cell system.

Exhaust treatment and filtration system for molten carbonate fuel cells

A method of producing a washcoated monolith catalyst utilizing a dual sol binder system, wherein the binder system is a blend of an alumina sol and a silica sol and wherein the ratio of the alumina to the silica in the dual sol binder system is from about 6:1 to about 1:3.

Method for washcoating a catalytic material onto a monolithic structure

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.

In a catalytic assembly having an oxidation catalytic unit disposed above the broiling area of a fat-food broiler for enabling the catalytic oxidation of volatile broiling smoke organic contaminants, a low pressure drop open-pore metallic flame-arresting filter screen disposed between the broiling area and the catalytic unit and substantially completely overlying the broiling area and containing upon the screen an adherent coating comprising a high surface area inorganic oxide adsorbent and an inorganic binder therefor, the coating serving to adhere salt, phosphorous and other catalyst-poisoning compounds in the broiling emissions. Preferred methods of coating and broiler flame-arresting use are described.

Method for the catalytic abatement of broiler emissions

A smoke abatement assembly is provided as an adjunct overlaying a cooking device such as a broiler or fryer system in a commercial restaurant. The smoke abatement assembly comprises a sealed housing which supports a low-pressure flame arrester, between 1 and 10 inches above the cooking area of the cooking device. A catalyst module is also removably mounted within the sealed housing above the flame arrester. The module includes a plurality of spaced low-pressure oxidation catalysts of controlled thickness, between 1 and 6 inches thick. The plurality of catalysts have a combined thickness equal to the thickness of a single catalyst providing the optimum catalyst volume or contact time for the installation. Each of the components, that is the flame arrester and plurality of catalysts, defines a smoke access area substantially equal to the cooking area of the broiler or fryer. A preheater can be provided to maintain the temperature at the catalysts at an optimum range during idle conditions when no cooking is occurring.
