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.

Systems and methods are provided for improving the operation of groups of reverse flow reactors by operating reactors in a regeneration portion of the reaction cycle to have improved flue gas management. The flue gas from reactor(s) at a later portion of the regeneration step can be selectively used for recycle back to the reactors as a diluent/heat transport fluid. The flue gas from a reactor earlier in a regeneration step can be preferentially used as the gas vented from the system to maintain the desired volume of gas within the system. This results in preferential use of higher temperature flue gas for recycle and lower temperature flue gas for venting from the system. This improved use of flue gas within a reaction system including reverse flow reactors can allow for improved reaction performance while reducing or minimizing heat losses during the regeneration portion of the reaction cycle.

The present disclosure refers to systems and methods for producing hydrogen among other products. In some embodiments the methods comprise sequentially conducting a cracking step in a fixed bed mode and conducting a flowing step in a fluidized bed mode. Such sequential processes may result in a number of advantages including, for example, regenerating the catalyst during the fluidized bed mode in a manner such that beneficial heat is generated for use in the endothermic cracking step.

A plant, such as a hydrocarbon plant, is provided, which has a syngas stage (A) for syngas generation and a synthesis stage (B) where said syngas is synthesized to produce syngas derived product, such as hydrocarbon product. The syngas stage (A) primarily includes electrically heated reverse water gas shift (e-RWGS) section. Additionally, an electrically-heated steam methane reforming (e-SMR) section (II) can be arranged in parallel to the e-RWGS section (I). The plant makes effective use of various streams; in particular CO2 and H2. A method for producing a product stream, such as a hydrocarbon product stream is also provided.

The present invention relates to the field of renewable energy. More specifically, the present invention relates to the production of biofuel from biomass including, for example, polymeric materials.

Disclosed herein is a method for converting an epoxide to a first C3 product, a second C3 product, and/or a first C4 product within an integrated system. The method includes converting the epoxide to a beta lactone to produce an outlet stream comprising beta lactone. The method includes converting the beta lactone of the outlet stream to a first C3 product in the first C3 reactor to produce an outlet stream comprising the first C3 product; converting the beta lactone to a second C3 product in the second C3 reactor to produce an outlet stream comprising the second C3 product, and/or converting the beta lactone to a first C4 product in the first C4 reactor to produce an outlet stream comprising the first C4 product.

Methods of catalytic process characterization using a reaction system having two or more reaction strands in a parallel arrangement, wherein each reaction strand has multiple series-connected reaction chambers or a single reaction chamber. Each reaction strand is supplied with a reactant stream subjected to process stages. Product streams discharged from the reaction strands are subjected to an analytical characterization, wherein the data achieved in the characterization are expressed in relative terms including the forming of a difference.
