PROTON CONDUCTING MEMBRANE

摘要

A reactor comprising a first zone comprising a dehydrogenation catalyst and a second zone separated from said first zone by a proton conducting membrane comprising a mixed metal oxide of formula (I) LnaWbO12-y wherein Ln is Y or an element numbered 57 to 71; the molar ratio of a:b is 4.8 to 6, preferably 5.3 to 6; and y is a number such that formula (I) is uncharged, e.g. y is 0 = y = 1.8.
