CATALYTIC MEMBRANE REACTOR FOR OXIDATIVE COUPLING OF METHANE .2. CATALYTIC PROPERTIES OF LAOCL MEMBRANES

This work presents the potential of a LaOCl porous membrane reactor fo r the reaction of oxidative coupling of methane. The sol-gel method pr ovided LaOCl membranes supported on alumina tubes which presented meso porous texture. Actually, the severe operating conditions of this reac tion caused textural instability which restricted any transport effect s to the macroporous domain. However, despite moderate separation effe cts between methane and oxygen, beneficial effects of the membrane rea ctor have been observed, subject to surface composition, structural an d feeding configuration requirements.
