The invention relates to membrane engineering, in particular to reactors for gas separation and/or for carrying out chemical reactions, namely to a reactor for extracting oxygen from an oxygen-containing gas and to a method for manufacturing the said reactor. The invented reactor for gas separation and/or for carrying out chemical reactions comprises a body (1), a ceramic membrane (2) and a connecting element (3) which is disposed there between and made of an alloy containing elements of the VII and VI groups of the Mendeleev's periodic table, wherein an aluminum oxide layer is formed on the connecting element surface which is adjacent to the membrane. The invented method for manufacturing the reactor for gas separation and/or for carrying out chemical reactions consists in fixing the ceramic membrane (2) in the reactor body (1) by means of the connecting element made of the alloy containing elements of the VII and VI groups of the Mendeleev's periodic table, wherein the used alloy is added with aluminum, prior to fixing the membrane (2), the connecting element (3) is heated in an oxygen-containing gas at a temperature ranging from 800 to 1100°C or an aluminum oxide layer is applied to the connecting element surface which is adjacent to the membrane. Reactor for gas separation and/or for carrying out chemical reactions and method for manufacturing thereof.
