A hydrocarbon is reacted with water in the presence of a catalyst to form hydrogen, carbon monoxide, and carbon dioxide. Hydrogen is selectively allowed to pass through a hydrogen separation membrane to a permeate side of a reactor, while water and carbon-containing compounds remain in a retentate side of the reactor. An outlet stream is flowed from the retentate side to a heat exchanger. The outlet stream is cooled to form a cooled stream. The cooled stream is separated into a liquid phase and a vapor phase. The liquid phase is flowed to the heat exchanger and heated to form steam. The vapor phase is cooled to form condensed water and a first offgas stream. The first offgas stream is cooled to form condensed carbon dioxide and a second offgas stream. The steam and the second offgas stream are recycled to the reactor.

The present invention describes a processes, systems, and catalysts for the conversion of carbon dioxide and water and electricity into low carbon or zero carbon high quality fuels and chemicals. In one aspect, the present invention provides an integrated process for the conversion of a feed stream comprising carbon dioxide to a product stream comprising hydrocarbons between 5 and 24 carbon atoms in length.

A process for producing hydrogen and pyrolytic carbon from hydrocarbons may involve converting hydrocarbons into hydrogen and carbon in a reactor at temperatures of 1000° C. or more. The reactor may include two electrodes spaced apart from one another in a flow direction of the hydrocarbons. In a region of the reactor between the electrodes an inert gas component is supplied over an entire reactor cross section. The reactor contains carbon particles in the region between the two electrodes. By introducing an inert gas component over the entire reactor cross section, deposition of carbon in this region of the reactor inner wall is prevented, thus effectively inhibiting the formation of conductivity bridges on the reactor inner wall.

An electrically heated reactor is a tube surrounded by electrical heating means having radiative sheeting placed coaxially with regard to the reactor tube. The surface area of the sheeting facing the outer surface area of the reactor tube defines an inner surface area covering at least 60% of the reactor tube outer surface area. The distance between the reactor tube and the heating means is selected such that the ratio between the inner surface area of the electrical heating means to the reactor tube outer surface area is in the range of 0.7 to 3.0. The reactor is useful in many industrial scale high temperature gas conversion and heating technologies.
