Abstract
This invention relates to a continuous process for the preparation of slush hydrogen. The process comprises substantially continuously injecting liquid hydrogen at a temperature slightly above its triple point temperature into a slush hydrogen generator; forming solid hydrogen by removing hydrogen vapor from the slush hydrogen generator; fracturing and dispersing surface solid as it is formed into the slush; concentrating the crystalline solid particles in the slush to a level of at least 30%, and preferably from 45 to 60%, by weight; and substantially continuously removing the slush hydrogen from said slush hydrogen generator at a rate such that a substantially constant level of slush is maintained in said slush hydrogen generator.
