Abstract: A reactor system includes a moving bed reactor that treats a lipid feedstock using a metal oxide catalyst to produce a treated stream comprising a bio-oil. The reactor system further includes a fluidized bed regenerator that regenerates spent metal oxide catalyst from the treating process in the moving bed reactor. Once the spent metal oxide catalyst is regenerated into metal oxide catalyst, it is returned to the moving bed reactor. The metal oxide catalyst returned to the moving bed reactor can contribute heat to the lipid feedstock to raise the lipid feedstock to a reaction temperature.

Abstract: A process includes flowing a catalyst composition comprising catalyst particles into a radial flow moving bed reactor, wherein the catalyst particles move by gravity through the radial flow moving bed reactor to an exit point of the radial flow moving bed reactor, wherein the catalyst particles form a moving catalyst bed in the radial flow moving bed reactor, flowing a light hydrocarbon feed stream comprising C1 to C3 alkanes into the radial flow moving bed reactor in a manner so that the light hydrocarbon feed stream flows radially inward or radially outward through the moving catalyst bed and thereby contacts the catalyst particles under reaction conditions to produce a product effluent stream comprising a C2 to C10 hydrocarbon product and hydrogen, and flowing the product effluent stream from the radial flow moving bed reactor.

Abstract: The present disclosure refers to systems and methods for the production, storage, and transportation of hydrogen. In a representative embodiment a reactor system comprises a fluidized bed combustor configured for reduced metal oxide oxidation and heat generation without significant greenhouse gas emission and/or with readily capturable emissions. The reactor system also comprises a liquid organic hydrogen carrier dehydrogenation reactor. The fluidized bed combustor is operatively coupled to the liquid organic hydrogen carrier dehydrogenation reactor. Advantageously, at least a portion of heat generated by the fluidized bed combustor may be transferred to the liquid organic hydrogen carrier dehydrogenation reactor. In this manner hydrogen production and transportation is both energy efficient, low carbon intensity and cost-effective.

Abstract: The present disclosure refers in one embodiment to processes for making and transporting clean hydrogen fuel. The processes may involve hydrotreating, hydrocracking, or both hydrotreating and hydrocracking an aromatic feedstock under conditions to obtain a liquid hydrocarbon fuel. The liquid hydrocarbon fuel is hydrogenated to obtain a hydrogen-rich fuel that is transported to a dehydrogenation facility that may also be at or near a hydrogen station. The hydrogen-rich fuel is used to obtain hydrogen and a second liquid hydrocarbon fuel.

Abstract: An improved nozzle device for a down-flow hydroprocessing reactor is disclosed. The down-flow nozzle is useful in the petroleum and chemical processing industries in catalytic reactions of hydrocarbon feedstocks in the presence of hydrogen, at an elevated temperature and pressure, to provide for the mixing and distribution of gas and liquid to reactor catalyst beds. Typical hydroprocessing applications include hydrotreating, hydrofinishing, hydrocracking and hydrodewaxing.
