The present technology is directed to processes involving formation of hydrocarbons and oxygenated hydrocarbons through use of oxygen supplied by ion transport membranes. More particularly, the present technology relates in part to a process involving steam reforming and subsequent production of a synthetic product where carbon dioxide and/or hydrogen downstream of the process is reclaimed to generate the synthetic product. The present technology also relates in part to an ethylene formation process involving a viral-templated coupling catalyst in the presence of an ion transport membrane.

A process and a plant for the continuous conversion of a hydrocarbonaceous feed gas into a synthesis gas comprising carbon monoxide and hydrogen, wherein the H.sub.2/CO molar ratio of the product gases can be varied within a wide range. This is achieved in that at least a part of a methane-rich gas obtained during the fractionation of the raw synthesis gas is admixed to the feed gas mixture, and that in the alternative at least a part of the H.sub.2 product gas and/or a fraction of a hydrogen-rich gas increased with respect to the normal operation of the process is admixed to the heating gas mixture, in order to lower the H.sub.2/CO ratio, or at least a part of the CO product gas and/or a fraction of a carbon monoxide-rich gas increased with respect to the normal operation of the process is admixed to the heating gas mixture, in order to increase the H.sub.2/CO ratio.

The invention relates to a plant and to a method for chemical looping oxidation-reduction combustion of a gaseous hydrocarbon feed, for example natural gas essentially containing methane. According to the invention, catalytic pre-reforming of the feed is performed in a pre-reforming zone comprising a fixed reforming catalyst, while benefiting from a heat transfer between the reduction or oxidation zone of the chemical loop and the pre-reforming zone adjoining the reduction or oxidation zone. Pre-reforming zone (130) and oxidation zone (110) or pre-reforming zone (130) and reduction zone (120) are thus thermally integrated within the same reactor (100) while being separated by at least one thermally conductive separation wall (140).

A fuel cell system according to the present invention includes a cell stack, a combustion part, a reformed water carburetor, a gas mixer, and a reformer. The cell stack is a cell stack that is configured by stacking fuel cells and generates electric power by using hydrogen-containing gas and oxygen-containing gas. The combustion part burns the hydrogen-containing gas and the oxygen-containing gas that have not been consumed in the cell stack. A reformed water carburetor is communicated with the combustion part via an exhaust gas passage and generates steam. The gas mixer, placed on the top of the combustion part. The reformer, placed on the top of the combustion part in contact with the gas mixer, is a reformer, generates the hydrogen-containing gas by reforming the mixed gas, and supplies the hydrogen-containing gas to the cell stack via the hydrogen gas passage.
