FIELD: chemistry.SUBSTANCE: method of drying and purifying hydrocarbon propellants involves combined deep drying and purification of hydrocarbon material, which is carried out by passing a liquid-phase mixture through sorbents in three series-arranged adsorbers. The first adsorber on the process path is filled with aluminium oxide, the second adsorber is filled with aluminium oxide or zeolite NaA and the third adsorber is filled with zeolite NaX or zeolite CaA or zeolite CaX.EFFECT: obtaining a ...

FIELD: chemistry.SUBSTANCE: method of producing hydrocarbon propellants involves combined drying and cleaning of hydrocarbon material and separating the hydrocarbon propellant composition. The hydrocarbon material used is propane, a butane fraction or isobutane or n-butane or propane or a mixture of propane and n-butane. Drying and cleaning is carried out by passing the material in liquid-phase through sorbents in three series-arranged adsorbers. The first adsorber on the process path is filled ...
