摘要： A method of converting one or more alkanes to one or more alkenes that includes a) providing a first stream containing one or more alkanes and oxygen to an oxidative dehydrogenation reactor; b) converting at least a portion of the one or more alkanes to one or more alkenes in the oxidative dehydrogenation reactor to provide a second stream exiting the oxidative dehydrogenation reactor containing one or more alkanes, one or more alkenes, oxygen, carbon monoxide and optionally acetylene; and c) providing the second stream to a second reactor containing a catalyst that includes a group 11 metal to convert a least a portion of the carbon monoxide to carbon dioxide and reacting the acetylene.

摘要： A system and method for coproduction in the production of ethylene, including contacting ethane with an oxidative dehydrogenation (ODH) catalyst in presence of oxygen in a first reactor to dehydrogenate ethane to ethylene, and contacting a first-reactor effluent with an ODH catalyst in a second reactor to form ethanol and acetaldehyde.

摘要： The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.

摘要： Oxidative dehydrogenation catalysts including mixed oxides of Mo, V, Nb, Te, and optionally a promoter may be dissolved in aqueous solutions of oxalic acid. This permits the removal of catalyst and catalyst residues from reactors for the oxidative dehydrogenation of paraffins and particularly ethane.

摘要： Mixed metal oxide catalysts having an amorphous content of not less than 40 wt. % are prepared by calcining the catalyst precursor fully or partially enclosed by a porous material having a melting temperature greater than 600° C. in an inert container including heating the catalyst precursor at a rate from 0.5 to 10° C. per minute from room temperature to a temperature from 370° C. to 540° C. under a stream of pre heated gas chosen from steam and inert gas and mixtures thereof at a pressure of greater than or equal to 1 psig having a temperature from 300° C. to 540° C. and holding the catalyst precursor at that temperature for at least 2 hours and cooling the catalyst precursor to room temperature.

摘要： If a cracked gas heat exchanger becomes damaged water may enter the transfer line causing it to rupture. This may be avoided using a heat exchanger having heat pipes to conduct heat from the cracked gas to a cooling device, typically a water cooler to generate steam. The latter (cooling device) is physical separated from the hot cracked gas stream. The heat pipes may be modified at the hot or cold end with fins, ribs, protuberances, pins and the like.
