Abstract:
A feedstock injector having a longitudinal axis, and comprising:(a) a first plurality of channels each having an upstream end and a downstream end, the first plurality of channels extending from the upstream end to an intermediate region of the injector, the fist plurality of channels disposed symmetrically about the longitudinal axis of the injector and shaped at their inlet ends to receive a stream of gas and to split the stream into a fist plurality of streams, each first plurality of channels having an outer wall and an inner wall, the plurality of inner walls substantially defining a first core segment therebetween; (b) a second plurality of channels each having an upstream end and a downstream end, the second plurality of channels extending from the intermediate region towards the downstream end of the injector, the second plurality of channels disposed symmetrically about the longitudinal axis and comprising at least two channels for each channel of the first plurality of channels, the upstream ends of the second plurality of channels connected to the downstream ends of the first plurality of channels and shaped to receive the streams of gas flowing through the first plurality of channels and to split the streams into a second plurality of streams, each channel of the second plurality of channels having an outer wall and an inner wall, the plurality of inner walls substantially defining a second core segment therebetween; (c) a feedstock input passage opening at the downstream end of the second core segment and oriented to direct feedstock axially in the downstream direction.
