摘要： A method for obtaining an olefin is disclosed, the method comprising subjecting a paraffin to dehydrogenation in the absence of oxygen and in the presence of a catalyst comprising a crystalline substrate, to obtain an olefin. The catalyst includes an inert stabilizing agent for maintaining the catalyst crystal structure. The catalyst may be regenerated by being subjected, in air, to a temperature between about 550° C. and about 750° C., for a period of time between about 15 minutes and about 4 hours.

摘要： The average cycle propylene selectivity of an oxygenate to propylene (OTP) process using one or more fixed beds of a dual-function oxygenate conversion catalyst is substantially enhanced by the use of moving bed reactor technology in the hydrocarbon synthesis portion of the OTP flow scheme in lieu of fixed bed technology coupled with the selection of a catalyst on-stream cycle time of 200 hours or less. Those provisions hold the build-up of coke deposits on the catalyst to a level which does not substantially degrade dual-function catalyst activity, oxygenate conversion and propylene selectivity, thereby enabling maintenance of propylene average cycle yield at essentially start-of-cycle levels. The propylene average cycle yield improvement enabled by the present invention over that achieved by the fixed bed system of the prior art using the same or a similar catalyst system is of the order of about 1.5 to 5.5 wt-% or more.

摘要： The present invention comprises a process for conversion of oxygenates to olefins comprising contacting within a reactor the oxygenates with a catalyst to produce light olefins and wherein the reactor comprises at least two zones, a first zone wherein gas circulates at a faster rate than a second zone wherein a gas circulates at a slower rate; and inserting a quantity of inert gas into the second zone to increase circulation of any materials located in said second zone. The invention prevents accumulation of undesirable by-products within stagnant zones within the reactor and reduces the amount of coke deposited on catalyst or on surfaces within these zones.
