    摘要： A device (HS) is provided with a refrigeration cycle unit (R) and a liquid hydrogen generation unit (P) for generating liquid hydrogen by cooling high-pressure raw material hydrogen by means of the refrigeration cycle unit (R) and by adiabatically expanding said raw material hydrogen by means of a Joule-Thomson valve (12). A first and second heat exchanger (E1, E2) are disposed along the refrigeration cycle unit (R) and the liquid hydrogen generation unit (P). The device (HS) is provided with a mechanism for generating liquid hydrogen by re-liquefying the boil-off gas generated in a liquid hydrogen storage tank. The boil-off gas is introduced into a hydrogen circulation path (1) at a section at which circulating hydrogen having an extremely low temperature flows, and the excessive circulating hydrogen generated therefrom is discharged to a raw material hydrogen path (11) from a section at which the circulating hydrogen is at room temperature.

    摘要： The present invention provides a method of liquefying a hydrogen feed stream and a liquefier for carrying out such a method in which ortho-species of hydrogen contained in a hydrogen feed stream is converted to the para-species in higher and lower temperature catalytic converters. An adsorption unit, located between the higher and lower temperature catalytic converters, adsorbs a portion of the ortho content of the feed stream. The adsorbed portion is desorbed during regeneration of an adsorbent bed of the adsorption unit and is recirculated back for treatment in the higher temperature catalytic converter to reduce the degree to which the ortho-species are converted to the para-species in the lower temperature catalytic converter and at lower temperatures.

    摘要： A compact and modular cryogenic method and apparatus for liquefying natural gas. The liquefaction process is highly efficient and requires no external refrigeration system, and the apparatus is small enough to be transportable from one remote site to another. A compressed natural gas feed stream is cooled and then expanded to form a bi-phase stream comprising a first refrigerated vapor component and a first liquid component. The first liquid component is then separated from the bi-phase stream and expanded to form a second bi-phase stream comprising a second refrigerated vapor component and a second liquid component. The second liquid component is then introduced into a means configured for storage and transport. The remaining feed stream can then be recycled, and at least a substantial portion of the original feed stream can be processed into liquefied natural gas (LNG). The first and second vapor components are recycled through the system and comprise at least a portion of the feed stream in the repeated steps.

    摘要： This invention presents improved combustion methods, systems, engines and apparatus utilizing H2, O2 and H2O as fuel, thereby providing environmentally friendly combustion products, as well as improved fuel and energy management methods, systems, engines and apparatus. The Water Combustion Technology; WCT, is based upon water (H2O) chemistry, more specifically H2O combustion chemistry and thermodynamics. WCT does not use any hydrocarbon fuel source, rather the WCT uses H2 preferably with O2 and secondarily with air. The WCT significantly improves the thermodynamics of combustion, thereby significantly improving the efficacy of combustion, utilizing the first and second laws of thermodynamics. The WCT preferably controls combustion temperature with H2O and secondarily with air in the combustion chamber. The WCT preferably recycles exhaust gases as fuel converted from water. The WCT minimizes external cooling loops and minimizes exhaust and/or exhaust energy, thereby maximizing available work and internal energy while minimizing enthalpy and entropy losses.

    摘要： Hydrogen is liquefied by a process comprising pre-cooling hydrogen feed gas by indirect heat exchange against pressurized liquefied natural gas (“LNG”) to produce pre-cooled hydrogen feed gas and pressurized natural gas, further cooling at least a portion of said pre-cooled hydrogen feed gas by indirect heat exchange against at least one refrigerant to produce condensable hydrogen gas and expanding at least a portion of said condensable hydrogen gas to produce at least partially condensed hydrogen. One advantage of such a process is that the power consumed during liquefaction is significantly less than that consumed in existing hydrogen liquefaction processes which pre-cool hydrogen feed gas by indirect heat exchange against other refrigerants, e.g. liquid nitrogen.
