摘要
The use of liquid hydrogen as a jet aircraft fuel has a number of environmental and technological advantages over conventional fuels. The liquefaction of hydrogen requires a large expenditure of energy. There are many inefficiencies that are a part of any practical liquefaction process. Current technology has been investigated for the best available system. Parametric studies have been made to identify where inefficiencies occur and to optimize and integrate the component parts. Flowsheets are presented for a module that will produce 250 ton per day of liquid hydrogen. Approximately ten of these modules would be needed for a major airport in the 1990s. The advantages of producing a product with a minimum amount of ortho to para hydrogen conversion are pointed out. The optimum degree of conversion has been determined for a liquid hydrogen product that will be used within a given time. An assessment has been made regarding the potentials for improvement of the processing schemes and equipment over the next 10–25 years.
