DOMESTIC STOVE OIL Russian patent published in 1999 - IPC

Abstract RU 2126439 C1

FIELD: liquid fuel production. SUBSTANCE: fuel contains fractions 180-dry point from secondary distillation of gasoline (1-10 wt %); catalytic cracking gas oil fraction 160-400 C (1-50 wt %); hydrofined straight-run oil distillate fraction 160-400 C (30-80 wt %) and catalytic cracking gas oil fraction 160-380 C, the two latter taken in proportion from 98:2 to 80:20; vacuum distillate fraction 280-480 C (2-20 wt %); and straight-run fraction 160-400 C (the balance). Addition of depressant Ц ethylene-vinylacetate copolymer with ethylene-to-vinylacetate link ratio from 1:10 to 10:1 and molecular weight from 100 to 80•104 in concentration 0.005-0.1% in the form of 2-80% solution in oil fraction 120-380 C results in decreased base fuel congelation point. EFFECT: optimized composition and lowered congelation point. 2 cl, 3 tbl
