It is an object of the invention to provide a reactor system based on an alkaline electrolysis system and an associated process for producing a synthetic fuel gas having a high proportion of oxygen from natural gas, biogas or exhaust gases from an internal combustion engine with hydrogen and oxygen formed in the electrolysis as fuel gas or synthesis gas. As a result of a high proportion of oxygen in the fuel gas of more than 20% by volume, the energy content of the new synthetic fuel gas is significantly higher than that of mixed gases already used in practice with a proportion of oxygen of less than 5% by volume. The arrangement of the reactor, including all additional systems, in a container allows largely standardized prefabrication on the part of the manufacturer of the reactor comprising the electrolysis system, including compliance with and installation of corresponding safety devices. The reactor system and the process for producing a fuel gas (25) from a carrier gas (11), e.g. natural gas (11), hydrogen, and oxygen utilize an alkaline low-voltage electrolysis system (3) which consists of a plurality of individual cells (4) within a reactor housing (2) and allows the fuel gas (25) to be formed in the individual cell (4) already during electrolysis. In spite of its high oxygen content, the fuel gas (25) is combustible but not explosive.
