METHOD FOR PRODUCTION OF HYDROCARBON PROPELLENTS Russian patent published in 1998 - IPC

FIELD: production of hydrocarbon propellents. SUBSTANCE: hydrocarbon raw materials are affected by rectification, thus hydrocarbon mixture having predetermined composition is prepared. Gage pressure of saturated steam of said mixture corresponds to gage pressure of saturated steams of hydrocarbon propellents. Then thus isolated hydrocarbon mixture is affected by preliminary purification together with its deodorization. The process is carried out on activated coal and is followed by drying, purification and deodorization which takes place on consequently disposed layers of NaA, CaA and NaX zeolites. Zeolites are regenerated with the help of nitrogen or with the help of dried and purified hydrocarbon gas. EFFECT: improved efficiency of the method, improved quality of product. 5 cl, 1 dwg
