Abstract
Centrifugal systems and methods of use thereof are provided. The systems and methods provide two-phase extraction/reaction and separation in a single operational unit. The systems are easily scalable and operable in a continuous manner. Also provided is a system and method for effecting catalytic reactions in an organic/reverse micelle system.
Claims51
A centrifugal reactor system, comprising:
- a. a chamber rotatable about an axis;
- b. a means for rotating said chamber about said axis;
- c. at least a first inlet means in communicative connection with said chamber for introducing a feed to said chamber, said feed containing at least one reactant;
- and
- d. at least a first outlet means in communicative connection with said chamber for removing liquid from said chamber;
- said chamber containing at least two liquid phases therein, said at least two liquid phases comprising a first phase and a second phase, said first phase and said second phase being in contact with each other within said chamber, said first phase comprising a catalyst system therein, said catalyst system selected to effect a desired reaction involving said at least one reactant of said feed, which reactant partitions into said first phase to contact said catalyst system and react to produce a reaction product, at least a portion of said reaction product partitioning into said second phase, said chamber being rotated at a tangential velocity to create sufficient centrifugal force to maintain a volume of said second phase as a substantially unmixed phase at a location of communicative connection of said first outlet means with said chamber, thereby enabling removal of an amount of said second phase from said chamber while minimizing loss of said catalyst system.

A method of performing a catalyzed reaction in a multiphase system comprising the steps of:
- a. introducing a feed containing at least one reactant into a chamber rotatable about an axis, said chamber containing at two liquid phases therein, said at least two liquid phases comprising a first phase and a second phase, said first phase and said second phase being in contact with each other within said chamber, said first phase comprising a catalyst system therein, said catalyst system selected to effect a desired reaction involving said at least one reactant of said feed, which reactant partitions into said first phase to contact said catalyst system and react to produce product, at least a portion of said product partitioning into said second phase;
- b. rotating said chamber at a tangential velocity to create sufficient centrifugal force to maintain a volume of said second phase as a substantially unmixed phase at a location of communicative connection of an outlet means with said chamber;
- and
- c. removing an amount of said second phase from said chamber via said outlet means.
