Modular reactors comprising a chassis, reactor tubing and optionally a cover are disclosed. The chassis comprises a plurality of channels of different lengths into which a length of reactor tubing is placed to create the reactor portion of the flow reactor.

A system for controlling contamination in hydrogen production from water-reactive aluminum includes at least one reaction vessel. For example, each reaction vessel may include a container, a conduit, and a plurality of baffles. The container may define a volume, and the conduit may define an orifice outside of the container and spaced away from the container. The plurality of baffles may be disposed in the volume to form a tortuous flow path through the volume to the orifice of the conduit to facilitate rapid production of a large quantity of hydrogen from water-reactive aluminum while reducing the likelihood that ejecta, aerosols, or a combination thereof, may escape the reaction vessel to interfere with end-use of the hydrogen produced.

A reactor shell for producing hydrogen and/or synthesis gas and/or carbon dioxide from a fed reactive mixture stream is provided.

A reactor shell for producing olefins via steam cracking from a fed reactive mixture stream composed of steam and hydrocarbons comprising: at least one reactive stream duct formed within said reactor shell, at least one structured ceramic bed having a plurality of hollow flow paths, at least one electrical resistance heating element for heating the reactive mixture stream up to a predetermined reaction temperature and a coating provided on a surface contacting with the reactive mixture stream is provided. The reactor shell is characterized by that said electrical resistance heating element that is arranged inside at least some of said hollow flow paths in a manner that there still remains a flowing passage inside the hollow flow paths.

The invention relates to a reformer furnace for catalytic reforming of a carbon-containing input material with steam. The reformer furnace has a steel construction which serves as a framework for a refractory lining and for the fastening of burners, reformer tubes and supply and discharge lines. The burners and reformer tubes are arranged in rows, parallel to one another and in alternating fashion. The steel construction includes a plurality of main carrier units, wherein each main carrier unit has at least two vertically extending supports and a horizontally extending main carrier which connects the supports. This type of steel construction makes it possible to achieve uniform spacing of the reformer tubes and burners over the entire reformer furnace. This results in advantages in terms of the maximum operating temperature of the reformer tubes, thereby extending their service life.

The invention relates to a reactor and a method for producing a product, wherein the reactor comprises an inner part which is formed at least in part from a porous material comprising a catalyst and in which at least one reactant is arranged to flow into the inner part and after that through the porous material to form a product, a shell structure which surrounds the inner part, a space between the inner part and the shell structure in which the product formed from the reactant in the porous material is arranged to flow out from the reactor, and a heating device for heating electrically the porous material. Further, the invention relates to the use of the reactor.
