Abstract:
A feedstock injector having a longitudinal axis, and comprising:(a) a plurality of major channels extending from the upstream end to the downstream end of the injector, the plurality of major channels arranged substantially symmetrical about the longitudinal axis and converging towards a major region of convergence at a downstream location, the major channels shaped at their inlet end to receive a stream and to split the stream into a plurality of streams, each major channel having an inner wall, the plurality of inner walls substantially defining a core therebetween;(b) a feedstock input passage located inside the core and oriented to direct feedstock axially towards the major region of convergence;(d) a feedstock-supply passages opening into the feedstock input passage; and(e) a plurality of minor channels located inside the core, the minor channels arranged substantially symmetrical about the longitudinal axis, each minor channel extending from the inner wall of a major channel towards a minor region of convergence located inside the core and connected to the feedstock input passage, the total cross-sectional area of the plurality of minor channels being smaller than the total cross-sectional area of the plurality of major channels.
