METHOD OF DRYING AND PURIFYING HYDROCARBON PROPELLANTS Russian patent published in 2014 - IPC C07C7/12 B01D53/04 C09K3/30 

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 product of high quality with low content of moisture and sulphur compounds, low operational and capital costs on carrying out the process.
