DIESEL FUEL DEPRESSANT AND A METHOD FOR PREPARATION THEREOF

摘要

FIELD: petroleum processing and petrochemistry. ^ SUBSTANCE: diesel fuel depressant contains 5-35% ethylene/propylene copolymer or ethylene/propylene/diene copolymer and 65-95% alpha-olefin fraction C20-C26. A method for preparation of the additive consists in that preliminarily prepared 5-35% solution of above-mentioned copolymer in alpha-olefin fraction C20-C26 is subjected to ultrasonic action on installation generating at frequency 22 kHz for 105 h. ^ EFFECT: improved all low-temperature characteristics of diesel fuel. ^ 2 cl, 2 tbl
