摘要： A process for producing methanol is described in which a hydrocarbon is steam reformed in a reforming zone, and during the reforming stage, of a cyclic steam reformer having a reforming stage and a regeneration stage, the steam reforming being conducted under conditions effective to produce a first effluent stream containing synthesis gas. Fuel and an oxygen-containing gas are combusted in the regeneration stage of the reformer so as to reheat the reforming zone to a temperature sufficient for the reforming stage and generate a flue gas. At least part of the first effluent stream is contacted with a methanol synthesis catalyst under conditions effective to convert synthesis gas to methanol and form a methanol-containing stream and a tail gas stream comprising unreacted carbon monoxide and hydrogen. At least part of the tail gas stream is recycled as fuel for the regeneration stage of the cyclic steam reformer.

摘要： This invention provides processes for transporting catalyst, preferably in an oxygenate to olefins reaction system. In one embodiment, an oxygenate contacts molecular sieve catalyst particles in a reactor under conditions effective to form an effluent stream comprising light olefins and forming coked catalyst particles. At least a portion of the coked catalyst particles are transported from the reactor or a device associated therewith to a catalyst regenerator through a conduit in a fluidized manner with a fluidizing medium comprising air and steam. At least a portion of the coked catalyst particles are regenerated in the catalyst regenerator to form regenerated catalyst particles, which are ultimately directed back to the reactor.
