AMELIORATION OF AMMONIA BREAKTHROUGH IN AN ALKANE AMMOXIDATION PROCESS |
摘要 |
The invention is a method for the reduction of ammonia breakthrough during t he manufacture of acrylonitrile comprising introducing a hydrocarbon selected from the group consisting of propane and isobutane; ammonia and an oxygen- containing gas into a lower portion of a fluid-bed reactor containing an ammoxidation catalyst to react in the presence of said catalyst to produce acrylonitrile. The method comprises introducing into the reactor at least on e C2 to C5 olefin which will react with at least a portion of the unreacted ammonia and oxygen present in the reactor to substantially reduce the amount of ammonia present in the reactor effluent exiting the reactor.
