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 In one embodiment, a plurality of catalyst particles, having a first median particle diameter, is withdrawn from the reaction system and is directed to a separation unit such as a counter flow cyclone separator.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.

摘要： This invention provides processes for maintaining a desired particle size distribution in an oxygenate to olefin reaction system. In one embodiment, the invention comprises replacing lost catalyst fines with less active co-catalyst particles. By adding less active co-catalyst particles to the reaction system, desirable fluidization characteristics and hydrodynamics can be maintained without affecting the overall (or primary catalyst) performance and product selectivities. The invention is also directed to a population of catalyst particles having a desirable particle size distribution well-suited for realizing ideal fluidization and hydrodynamic characteristics.

摘要： The present invention provides a process for producing synthesis gas blends which are especially suitable for conversion either into oxygenates such as methanol or into Fischer-Tropsch liquids. Such a process involves reforming of two separate gaseous hydrocarbon feedstreams (formed, for example, by dividing a natural gas feedstock) in a steam-reforming unit and an oxygen-blown reforming unit, respectively. The syngas effluent from each reforming unit is then combined, after appropriate pressure adjustments, to realize a synthesis gas blend containing selected amounts and ratios of H2, CO and CO2. In further invention embodiments, processes are provided for converting the resulting syngas blends into oxygenates or Fischer-Tropsch hydrocarbons. Further conversion of the oxygenates so produced into light olefins also constitutes part of this invention.

摘要： The present invention is directed to a method and system for integrating a catalyst regeneration system with a plurality of hydrocarbon conversion apparatuses, preferably, a plurality of multiple riser reactor units. One embodiment of the present invention is a reactor system including a plurality of reactor units, at least one reactor unit preferably comprising a plurality of riser reactors. The system also includes a regenerator for converting an at least partially deactivated catalyst to a regenerated catalyst. A first conduit system transfers the at least partially deactivated catalyst from the reactor units to the regenerator, and a second conduit system transfers regenerating catalysts from the regenerator to the plurality of reactor units. Optionally, catalysts from a plurality of hydrocarbon conversion apparatuses may be directed to a single stripping unit and/or a single regeneration unit.

摘要： This invention is directed to a process for producing methanol. The methanol product that is produced according to this invention is achieved with a high conversion of synthesis gas. The high conversion of synthesis gas is achieved by flowing a liquid layer across a plurality of catalyst beds countercurrent to the gas flow. The gas containing methanol product exiting each bed flows through the liquid layer. The liquid acts to extract methanol from the gas, as well as cool the gas.

摘要： This invention is to a circulating fluid bed reactor that is designed so as to have the ability to adjust catalyst holdup within the reaction zone of the reactor while maintaining substantially constant catalyst circulation rate through the reaction zone. The ability to adjust catalyst hold up independently of catalyst circulation rate provides an advantage of having the ability to maintain a constant conversion level as catalyst activity or feed rates change.
