Abstract: A high pressure hydrazine gas generator having a decomposition chamber which contains therein an initiator of I.sub.2 O.sub.5 crystals and a plurality of heat retaining balls. The liquid hydrazine which is initially introduced into the decomposition chamber, ignites upon contact with the initiator and creates a high temperature within the decomposition chamber. This high temperature is maintained within the chamber by the heat retaining balls and therefore sustains decomposition of the liquid hydrazine into gases which are emitted from the generator under extremely high pressure.

Abstract: Apparatus for the processing of solid fuel hydrocarbons including a reactor for hydrogenation of the fuel reactant and a combustion reactor for oxidation of the residuum from the first reactor, the solid fuel reactant being dissolved in molten salt throughout its processing; and heat recovery means including a molten metal loop and a steam loop whereby the excess heat from the hydrogenation and oxidation reactors, present in the molten salt reaction matrix, is recovered in molten metal and transferred to the steam loop for energy production while avoiding cross contamination of the steam loop with salt from the reaction loop, and vice-versa.
