摘要

Abstract

The catalytic oxidative coupling of methane (OCM) to C

hydrocarbons (C

and C

) represents one of the most effective ways to convert natural gas to more useful products

which can be performed effectively using La

(BSCF) perovskite layer onto the outer LSCF surface to improve the oxygen permeation were evaluated. Between 700 ℃ and 1000 ℃

methane conversion increased in the order of uncoated

and BCG-coated LSCF hollow fiber while C

uncoated

and BCG-coated LSCF hollow fiber. Oxygen permeation flux at the same temperature range

on the other hand

was enhanced in the order of uncoated

BCG-coated

and BCG an

d BSCF-coated LSCF hollow fiber. This finding demonstrates the complex interplay between oxygen permeation and OCM performance. The BCG and BSCF-coated hollow fiber was also subjected to thermal cycles between 850 ℃ and 900 ℃ for up to 175 hours during which the fiber showed minor degradation in oxygen permeation fluxes and relatively stable OCM performance.
