One Component Membrane Reactor for Partial Oxidation of Methane Using Asymmetric Membranes

摘要

Oxygen permeable asymmetric membranes of Ca_(0.8)Sr_(0.2)-Ti_(0.7)Fe_(0.3)O_(3-δ) were applied to a one-component membrane reactor (OCMR) for the partial oxidation of methane. CH4 conversion and oxygen flux of OCMR with a 43-μm dense layer at 1173K reached 71% and 1.7 mLmin~(-1) cm~(-2), respectively. These values are 2.5 times greater than that of a 500-u.m self-supported membrane.
