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.

Objects of the present invention are to provide a novel dehydrogenation reaction catalyst, to provide a method that can produce a ketone, an aldehyde, and a carboxylic acid with high efficiency from an alcohol, and to provide a method for efficiently producing hydrogen from an alcohol, formic acid, or a formate, and they are accomplished by a catalyst containing an organometallic compound of Formula (1). ##STR00001##

Systems and methods for selectively extracting hydrogen gas dissolved in oil are provided. In one embodiment, a system includes a selectively permeable membrane provided at a point of contact between oil and a sensor chamber. The selectively permeable membrane has a hydrogen specificity and a thickness selected to minimize detection of further gasses dissolved in the oil by a hydrogen gas sensor cross-sensitive to the further gasses. The selectively permeable membrane can include polyimide. The further gasses include carbon monoxide, acetylene, and ethylene. The system can include a further membrane and a porous metal disc. The porous metal disc is bound to the selectively permeable membrane by using the further membrane as an adhesive layer and by applying pressure and temperature. The porous metal disc supports the selectively permeable membrane and the further membrane against pressure of the oil when exposed to a vacuum. The further membrane includes fluorohydrocarbons.

The energy is minimized that is required to lower the concentration of the high boiling point components (containing the poisoning substance for the dehydrogenation catalyst) contained in the hydrogenated aromatic compound produced by the hydrogenation of an aromatic compound. The hydrogenation system (2) for an aromatic compound comprises a hydrogenation reaction unit (11) for adding hydrogen to an aromatic compound by a hydrogenation reaction to produce a hydrogenated aromatic compound, a first separation unit (12) for separating a gas and a liquid component from a product of the hydrogenation reaction unit while maintaining a temperature of the product generally higher than a boiling point of the hydrogenated aromatic compound, and a second separation unit (13) for separating the hydrogenated aromatic compound from the gas component separated by the first separation unit.

This disclosure pertains to a supported noble metal catalyst containing noble metal component and a sulfur-containing component being supported on a non-noble metal doped inorganic oxide carrier and uses thereof. The catalyst may be used for the hydrogenation of an aromatic compound. The present disclosure further relates to a process for the partial or complete dehydrogenation of perhydrogenated or partially hydrogenated cyclic hydrocarbons to produce hydrogen.

A method for subsurface hydrogen storage and hydrogen retrieval. The method includes identifying a subsurface formation, wherein the subsurface formation is selected from one or more of a depleted wet reservoir, depleted dry reservoir, salt cavern, excavated cavern, natural formation, isolated aquifer, or a reservoir designated as a contingency or marginal field. The method further includes selecting a liquid organic hydrogen carrier (LOHC) feed compatible with the subsurface formation. The LOHC feed includes a mixture of one or more completely or partially hydrogenated LOHCs. The LOHC feed is injected into the subsurface formation for storage. Later, when needed, the LOHCs are recovered from storage, optionally separating a recovered water/brine phase and off gas from the LOHCs from storage in a separator configured to produce a stream of recovered LOHCs. The LOHC is then dehydrogenated to form a H2 product and dehydrogenated LOHCs in a dehydrogenation unit process.
