Abstract:
A system for providing a mixture of an oxygen-bearing gas and a gaseous reactant stream to a fluidized bed reactor to produce nitriles, comprising:a source of a first oxygen-bearing gas coupled to said fluidized bed reactor;a reactant gas stream comprising ammonia and propylene;sparger means for entraining oxygen into said reactant gas stream;feed means coupling said sparger means to said fluidized bed of said reactor, for introducing said reactant gas stream and entrained oxygen directly into contact with said fluidized bed; andcontrol means for controlling feed of said oxygen to said sparger means so as to entrain sufficient oxygen into said reactant gas stream to assure that said fluidized bed experiences an oxygen sufficiency at a point of feed injection of said reactant gas stream and entrained second oxygen-bearing gas for production of said nitriles.
