Abstract
A downflow reactor, e.g. a downer reactor or system, includes an outer wall defining an interior reactor space. An elongated plug is within the outer wall having a first end and a second end, defining a longitudinal axis between the first and second ends. A distribution baffle positioned at a vertical position between the first end and the second end of the elongated plug configured and adapted to direct hot down flowing catalyst towards a feedstock spray.
Claims23
A downflow reactor comprising:
- an outer wall defining an interior reactor space;
- an elongated plug within the outer wall having a first end and a second end, defining a longitudinal axis between the first and second ends;
- and
- a distribution baffle positioned at a vertical position between the first end and the second end of the elongated plug configured and adapted to direct hot down flowing catalyst towards a feedstock spray, wherein the distribution baffle includes a converging section and a constant-area section, wherein the converging section converges from an upstream end of the distribution baffle towards a downstream end of the distribution baffle.
