PROCEDURE DETERMINING SORT OF DIESEL FUEL CARRYING NO DEPRESSANT ADDITIVES Russian patent published in 2003 - IPC

Abstract RU 2207565 C1

FIELD: analytical determination of sort of diesel fuel (summer or winter) carrying no depressant additives at sites of its utilization. SUBSTANCE: procedure consists in determination of sort of diesel fuel by value of sorption index m which is found by given design formula. Indicator tubes presenting glass microchromatographic columns filled with sorbent (zeolite, brand NaX) treated beforehand are employed in realization of procedure. Tubes with sorbent are brought into contact with analyzed fuel through lower butts of tubes and length of zones L1 and L2 of sorbent wetting is found in preset time intervals of 3 and 9 min. Then sorption index is calculated by design formula m = L22

/L2-L1. When m ≤ 150 fuel is summer fuel, when m >150 - fuel is winter fuel. EFFECT: development of proximity procedure determining sort of diesel fuel. 2 tbl
