A hydrocarbon gas such as methane and LPG is desulfurized in the presence of oxygen and an oxidation catalyst to convert sulfur compounds in the gas to sulfur oxides. The sulfur oxides are then trapped downstream of the oxidation by an adsorbent. The amount of oxygen added to the hydrocarbon gas to promote oxidation is such that the sulfur compounds are selectively oxidized and the oxidation of the hydrocarbon gas is minimized to reduce hydrogen formation.

Method of desulfurizing a hydrocarbon gas by selective partial oxidation and adsorption

A composition for abatement of airborne pollution by volatile organic compounds (&ldquo;VOCs&rdquo;) has an upstream composition which contains a protective adsorbent, e.g., Y zeolite, which is effective for adsorbing large VOC molecules, e.g., toluene, and a protective oxidation catalyst intimately intermingled therewith. The downstream composition contains a second adsorbent, e.g., a silver-containing ZSM-5, which is effective for adsorbing relatively smaller VOC molecules, e.g., propylene, and a second oxidation catalyst intimately intermingled therewith. Oxidation of VOCs while they are still retained on the adsorbents is promoted at temperatures lower than would be required if the VOCs were desorbed into the gaseous phase. Apparatus is provided including a first contact member (,) coated with the upstream composition and positioned upstream of a second contact member (,) coated with the downstream composition. A heat exchanger (,) equipped with a temperature control device (,) is positioned upstream of both contact members to vary the treatment temperature between an adsorption temperature range and a higher, oxidation temperature range, both lying within an operating temperature range of from about 20 to 500&deg; C.

A pre-vaporized fuel system for use in fueling an internal combustion engine is provided with a dynamic infrared sensor. The infrared sensor senses the hydrocarbon content of the vaporized fuel which information is used by the engine control module to control engine fueling to minimize emissions. The infrared source is operated to maintain the pre-vaporized fuel below its lower explosive limit and the thermopile detector electronics is synchronized with the light pulse frequency to develop fast signal responses suitable for fueling control.

A catalyzed hydrocarbon trap material washcoat (20) used in a trap (10), which may be placed downstream of a conventional catalyst member (28), is useful for treating internal combustion engine (22) exhaust. Trap (10) traps hydrocarbons during cold operation periods and releases them for oxidation during higher-temperature operating periods. The material comprises palladium and silver dispersed on a high surface area metal oxide support and a zeolite material such as one or more of ZSM-5, Beta, Y, and other suitable zeolites. The trap material is efficiently made by combining in a single vessel the zeolite, the metal oxide support, and aqueous solutions of a palladium compound and a silver compound. Surprisingly, the intimate combination of silver with the palladium does not adversely affect catalytic efficiency of the palladium and provides advantageous results in enhancing catalytic oxidation of hydrocarbons desorbed from the trap (10) and coke which forms thereon.

A method of at least periodically removing from a lean gaseous stream a sorbable component such as SO.sub.x includes passing the gaseous stream through a trap member having an oxidation catalyst combined with a sorbent material at a temperature within the sorbing temperature range of the sorbent material. The sorbed component is periodically removed by introducing a combustible component into the gaseous stream and oxidizing it on the trap member to thermally desorb the sorbed component. The amount of combustible component introduced is limited to maintain the gaseous stream composition lean, but is sufficient to increase the surface temperature of at least part of the trap member to above the bulk temperature of the gaseous stream. Sorbing and desorbing periods are alternated and a composition and an apparatus to carry out the process is provided.
