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.
Claims28
A process for producing hydrocarbons comprising:
- contacting a gas stream in a multiphase reactor having a reaction zone having a central region, an outer region and comprising internal structures arranged to configure at least one dense region and one lean region of internal structures within the reaction zone under conditions effective to produce synthesis products, wherein at least a portion of the synthesis products are liquid under the operating conditions of the multiphase reactor and wherein the configuration of internal structures reduces the radial variation of the axial resistance to flow within the reactor.
