摘要： This invention is directed to methods for forming an olefin stream from a methanol stream. A lower grade methanol, such as chemical grade or crude methanol, can be used as feed to form the olefin stream. The process uses a relatively simple distillation type step to vaporize a portion of the methanol feed stream and send the resulting vapor stream to a reaction unit to form the olefin stream. In addition, the invention provides the ability to operate the downstream recovery units with reduced fouling or plugging due to the presence of fine solids components.

摘要： This invention is directed to a process for making a methanol product from a synthesis gas (syngas) feed using a fluid bed reactor. Internal reactor heat transfer is balanced between feed preheat and catalyst bed temperature using appropriate backmixing of feed and catalyst. Backmixing can be appropriately controlled using a number of control points, including any one or more of superficial gas velocity, catalyst density in the reactor, reactor height to diameter ratio (preferably at least in the region of the dense catalyst bed), and catalyst particle size.

摘要： Catalyst losses are prevented in riser reactor systems by using a low inlet velocity for the first cyclone separator in each multi-stage cyclone separator in the reactor. Catalyst particles not separated from the product output flow in an oxygenate-to-olefin reactor are also recaptured by cooling the product output flow and passing the flow through an electrostatic precipitator.

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： The present invention provides various processes for selectively removing undesirably sized catalyst particles from a reaction system. In one embodiment, a plurality of catalyst particles, having a first median particle diameter, is withdrawn from the reaction system and is directed to a separation unit such as a counter flow cyclone separator. In the separation unit, the particles are separated into a small catalyst stream and a large catalyst stream, the small catalyst stream having a second median particle diameter less than the first median particle diameter, and the large catalyst stream having a third median particle diameter greater than the first median particle diameter. At least a portion of the small or large catalyst stream is then directed back to the reaction system in order to maintain a desirable particle size distribution therein.
