The present invention relates to a process for generation of heat and/or power comprising a membrane reactor where a fuel is oxidized and further comprising an improved method for reducing emissions of carbon dioxide and emission of oxides of nitrogen from said process. There is applied a membrane reactor being a mixed oxygen ion and electron conducting membrane reactor comprising a first surface (feed side) capable of reducing oxygen to oxygen ions and a second surface (oxidation side) capable of reacting oxygen ions with a carbon containing fuel. The carbon containing fuel is mixed with recycled CO.sub.2 and H.sub.2 O containing exhaust gas before being supplied to the oxidation side of the membrane reactor. The air is heated before being supplied to the feed side of the membrane reactor at about atmospheric pressure. The CO.sub.2 containing gas mixture from the process can be injected in an oil and gas reservoir for enhanced oil recovery or to a geological formation.

[ What is claimed is:] [1.]1. A process for generating heat or power, or both, comprising:providing a membrane reactor, the membrane reactor comprising a first feed side surface and a second oxidation side surface, the first and second surfaces being connected by a mixed oxygen ion and electron conducting membrane, wherein oxygen contacting the first feed side surface is reduced to oxygen ions, wherein the oxygen ions are conducted through the conducting membrane to the second oxidation side surface, and wherein the oxygen ions are oxidized to oxygen at the second oxidation side surface,supplying an air stream to the first feed side surface of the membrane reactor, wherein oxygen contained in the air stream is reduced to oxygen ions, which oxygen ions are conducted by the conducting membrane to the second oxidation side surface of the membrane reactor,mixing a carbon containing fuel and a recycled CO.sub.2 --H.sub.2 O containing exhaust gas,supplying the mixture of carbon containing fuel and recycled CO.sub.2 --H.sub.2 O containing exhaust gas to the second oxidation side surface of the membrane reactor, wherein the mixture is contacted with the oxygen ions on the second oxidation side surface to oxidize the oxygen ions to oxygen,causing a combustion of the oxygen and mixture of carbon containing fuel and recycled CO.sub.2 --H.sub.2 O containing exhaust gas, which combustion generates a CO.sub.2 --H.sub.2 O containing exhaust gas, andfeeding the CO.sub.2 --H.sub.2 O containing exhaust gas to a recovery system for heat or power, or both, thereby generating heat or power, or both.
