Abstract
A multi phase catalytic reactor in which a liquid product is separated from a slurry phase containing a finely divided solid catalyst in a liquid medium. The apparatus includes a vessel which contains a number of vertical reaction tubes, arranged to accommodate the slurry phase. Each tube has a filter member in contact with the slurry phase within the tube. The filter members thus define a filtrate zone which is separated from the slurry phase. Gaseous reactants are introduced into the slurry phase within the tubes and a heat exchange medium is circulated around the outside of the tubes.
Claims36
A multi-phase catalytic reactor in which a liquid product is separated from a slurry phase which contains a finely divided solid catalyst in a liquid medium, the apparatus comprising:
- a) a vessel;
- b) a plurality of vertical reaction tubes within said vessel, said tubes being arranged to accommodate said slurry phase and thereby defining a reaction zone;
- each tube having a filter member in contact with said slurry phase within said tube, said filter members collectively defining a filtrate zone which is separated from said slurry phase;
- c) means for introducing gaseous reactants and/or other components into said slurry phase within said tubes;
- and d) means for circulating a heat exchange medium within a portion of said vessel defined by internal walls of said vessel and external walls of said tubes.
