A method for degassing flowable fluids, in particular liquids used for hydrogen storage, uses a device including a desorber (12) that can be filled with fluid to be degassed and through which the fluid can flow. A circulation pump (48) circulates the fluid during a degassing process in the desorber (12). A vacuum pump (38) generates a vacuum in the desorber (12) during a filling step with fluid and for discharging the gas from the desorber (12) during the degassing step. At least one sensor (44a, 44b) measures the pressure in the desorber (12) and/or a dwell time. A control unit ends the degassing process when a predefined pressure is measured by the sensor (44a, 44b) and/or when a predefined dwell time of the fluid in the desorber (12) is measured.

The present disclosure relates generally to portable energy generation devices and methods. The devices are designed to covert formic acid into released hydrogen, alleviating the need for a hydrogen tank as a hydrogen source for fuel cell power. In particular, an electricity generation device for powering a battery comprising a formic acid reservoir containing a liquid consisting of formic acid; a reaction chamber capable of using a catalyst and heat to convert the formic acid to hydrogen and carbon dioxide; a fuel cell that generates electricity; a delivery system for moving converted hydrogen into the fuel cell; and a battery powered by electricity generated by the fuel cell is provided.

The present invention relates to the fuel production device including the internal combustion engine, an electrolysis device connected to the internal combustion engine, and a hydrogenation reactor connected to the electrolysis device, wherein the electrolysis device is a device for decomposing high-temperature water vapor contained in the exhaust gas from the internal combustion engine into hydrogen and oxygen, and the hydrogenation reactor is a device for converting the hydrogen resulting from the decomposition to the fuel.

Mixed metal metal-organic frameworks (MM-MOFs) of copper-1,3,5-benzenetricarboxylate (BTC), M—Cu-BTC, wherein M is Zn(II), Ni(II), Co(II), and/or Fe(II) may be made using post-synthetic exchange (PSE) with metal ions. Such MM-MOFs may be used in H.sub.2 storage, especially Ni(II) and Co(II) MM-MOFs. Selected metal exchanged materials can provide gravimetric H.sub.2 uptake around 1.63 wt. % for Zn—Cu-BTC, around 1.61 wt. % for Ni—Cu-BTC, around 1.63 wt. % for Fe—Cu-BTC, and around 1.12 wt. % for Co—Cu-BTC.

A catalyst for a dehydrogenation reaction includes a carrier including Al.sub.2O.sub.3 having a theta (θ) phase, an active metal supported on the carrier and including a noble metal, and an auxiliary metal supported on the carrier and different from the active metal.

A low-temperature dehydrogenation method includes a dehydrogenation reaction of a reactant including a piperidine-based compound substituted with one or more alkyl groups.
