摘要： 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.

摘要： 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.
