Abstract:
1. In a bubble column reactor for reacting a predominately liquid-phase stream and a predominately gas-phase stream, the improvement comprising: a vessel shell defining an elongated reaction zone, wherein said vessel shell is elongated along a central shell axis, wherein said reaction zone presents axially-spaced normally-upper and normally-lower ends; one or more gas openings for introducing said predominately gas-phase feed into said reaction zone; one or more liquid openings for introducing said predominately liquid-phase feed into said reaction zone; and one or more baffles disposed in said reaction zone generally above at least one of said gas openings, wherein said baffle comprises a plurality of laterally-spaced baffle members, wherein said baffles present one or more exposed outer surfaces, wherein less than about 50 percent of the total upwardly-facing surface area of said exposed outer surfaces is formed by substantially planar surfaces inclined less than about 20 degrees from horizontal.
