摘要： A mixed metal oxide, which may be an orthorhombic phase material, is regenerated, selectively enriched or selectively poisoned as a catalyst to reduce catalyst aging for the production of unsaturated carboxylic acids, or unsaturated nitriles, from alkanes, or mixtures of alkanes and alkenes. Regeneration is effected by contacting said mixed metal oxide with a an oxidizing gas such as oxygen, air, steam and combinations thereof in a regenerator at a temperature of from 300°C to 600°C to form said regenerated catalyst.
The catalyst is enriched by re-metallizing the mixed metal oxide using a volatile organometallic compound.
Catalyst lifetime is extended by reversing flow direction of reactants.

摘要： Nitrogen oxide storage catalysts are used to remove nitrogen oxides from the lean exhaust gas of so-called lean engines. By being exposed to high temperatures during vehicle operation, said catalysts are subjected to thermal aging processes affecting nitrogen oxide storage catalysts and precious metals containing catalytically active components. The present invention relates to a method by means of which the catalytic activity of a nitrogen oxide storage catalyst lost as a result of the thermal aging process may be at least partially restored, containing as catalytically active compounds, in addition to platinum, alkaline compounds of strontium and/or barium on a carrier material containing ceroxide. The dual-stage method is based on the fact that the carrier material may be used to return strontium and/or barium compounds formed during thermal aging to the catalytically active form thereof by targeted treatment with special gas mixtures.

摘要： A method and associated apparatus for regenerating and/or stabilizing catalyst used in dehydrogenation of alkylaromatic hydrocarbons is disclosed. The alkylaromatic hydrocarbon (1) and steam (2) are combined to form feedstream (3) and pass into reactor (50). The ensuing product stream (4) is reheated in heater (52) to restore the heat lost and passed as partially converted reactant stream (5) into second reactor (54) and leaves as stream (6) comprising the dehydrogenation product. Restoration and/or stabilization of catalyst is accomplished by an alkali metal compound which is fed into feedstream (2) and/or product stream (5) via supply means (46 and 66), respectively. The amount of alkali metal compound entering the reactor(s) is monitored by means (42 and 62) which may in turn be coupled to activating means (44 and 64) to signal and activate the supply means. This method and apparatus permit the restoration and/or stabilization of the catalyst to be performed without interrupting the dehydrogenation reaction.

摘要： A low-temperature chemical vapor deposition (CVD) apparatus and a method of synthesizing carbon nanotubes using the CVD apparatus. The thermal CVD apparatus includes: a reaction tube having a gas inlet portion and an exhaust portion, the reaction tube divided into a first region, which is spatially adjacent to the gas inlet portion, for thermally decomposing a gas entering through the gas inlet portion, and a second region, which is spatially adjacent to the exhaust portion, for synthesizing carbon nanotubes using the gas decomposed in the first region; a first resistance heater installed around the reaction tube, for maintaining the temperature of the first region at a first temperature; a second resistance heater installed around the reaction tube, for maintaining the temperature of the second region at a second temperature lower than the first temperature; and an insulator interposed between the first and second resistance heater for insulating the same. The carbon nanotube synthesis method includes forming a first metal catalyst film over a first substrate. The first metal catalyst film is etched with an etching gas to form a number of nano-sized catalytic particles, and a carbon source gas is thermally decomposed using a thermal chemical vapor deposition (CVD) apparatus having a reaction tube divided into first and second regions, maintained at different temperatures, wherein the carbon source gas is decomposed in the first region, which is a relatively high temperature region, of the reaction tube. Then, carbon nanotubes are synthesized over the catalytic particles using decomposed carbon source gas, in the second region whose temperature is lower than the first region.
