ABSTRACT:
The present invention provides an apparatus and method for optimizing the degree of backmixing within a gas agitated multiphase reactor at a given gas linear velocity. The embodiments of the present invention involve novel configurations of the multiphase reactor internal structures. In general, the configurations comprise creating a dense area of internal structures in the central region and/or wall regions of the multiphase reactor.
