(381f) Nineteen-Bore Hollow Fiber Membranes Fabrication and Applications in Oxygen Separation and Membrane Reactor

Hollow fiber membrane configuration owing to its unique, one-step formed asymmetric structure, thin separation layer and hence advanced oxygen permeation performance are intensively studied in recent years. There are large amount of reports can be found in regard to single bore hollow fibers. Although hollow fiber membranes have many advantages, their applications are limited by their brittleness when a force impingement or thermal shock occurred. Inspired by the nineteen channel monolithic membranes (in a diameter of more than 40 mm) which are wildly used in water filtration as their high flux and mechanical strength, we challenged BSCF nineteen-bore hollow fiber membranes in a small diameter of 4 mm. Existence of different paths for oxygen transport in the nineteen-bore hollow fiber were successfully demonstrated. The design of multi-bore hollow fiber will be easily exploited to build oxygen separator or membrane reactor, showing a prospect of commercialization.
