Title: Oxidation catalyst and method of use
Inventor: VOSS KENNETH E
IPC: F24C15/20
Filed: 1992-11-20
Abstract: Oxidation catalyst compositions include a catalytic material having a BET surface area of at least about 10 m2/g and consisting essentially of a combination of bulk ceria and a bulk second metal oxide which may be one or more of titania, zirconia, ceria-zirconia, silica, alumina-silica and .alpha.-alumina. The combination may optionally also include activated alumina having a BET surface area of at least about 10 m2/g. The ceria, second metal oxide and optional activated alumina may be mixed together or provided as discrete layers. Optionally, one of platinum or palladium metal may be dispersed on the catalytic material provided that the platinum, when used, is used in limited amounts to preclude excessive oxidation of SO2 to SO3. The catalyst compositions may be used for oxidation of oxidizable components in a gas-borne stream, e.g., in a method to treat diesel engine exhaust by contacting the hot exhaust with the catalyst composition to promote the oxidation of the volatile organic fraction. The optional inclusion of platinum or palladium promotes the oxidation of gas phase components, e.g., hydrocarbons and carbon monoxide.

Title: Dermatological agent for aiding oxygen transport in the skin
Inventor: ROEDING JOACHIM
IPC: A61K31/535
Filed: 1993-06-24
Abstract: The invention relates to a dermatological agent for assisting the transport of oxygen in the skin, a process for its preparation and the use thereof. The problem with the known dermatological agents is the inadequate supply of oxygen to the skin and the adjoining tissue. The object of the invention is therefore to get through the horny layer of the skin and the epidermis by penetration processes in order to increase the oxygen concentration in the dermal area and adjoining tissue and to activate metabolic processes. According to the invention, this is effected by means of a dermatological agent containing asymmetric lamellar aggregates, consisting of phospholipids and oxygen-laden fluorocarbon or fluoro-carbon mixture, the amount of fluorocarbon being in the range from 0.2 to 100 % weight/volume, in a carrier which is suitable for dermatological use. Preparation is effected by emulsification of the corresponding constituents,  and use in ointments, creams, lotions, waters, alcoholic extracts, pastes, powders, gels, tinctures or on dressings and plasters or in a spray.
