Georg HerbergVarious studies have indicated that hydrogen-oxygen propellant systems offer significant advantages over other propellants for short-time space missions. The advantages include weight savings as reflected by an excellent specific fuel consumption and an inherent ability of the cryogenic fluids to absorb large heat inputs.Diverticulitis 发表于 2025-3-24 05:10:49

Georg Herberg. The hydrogen product contains about 10 to 13 mole % nitrogen as dictated by the equilibrium conditions at the top of the scrub towers. This nitrogen impurity can be tolerated because the final synthesis gas contains 25 mole % nitrogen.
