METHOD AND DEVICE FOR MEASURING BLEND RATE OF BIODIESEL-FUEL-BLENDED LIGHT OIL AND ESTER RATE OF FAME

摘要

The purpose of the present invention is to provide a method and a device for measuring the blend rate of FAME in a biodiesel-fuel-blended light oil and the ester rate which is the rate of triglycerides in FAME. Disclosed are a method and a device for measuring the blend rate of a biodiesel-fuel-blended light oil and the ester rate of FAME, wherein: a cylindrical upright transparent vessel constitutes an analysis vessel (1); the upper section of the analysis vessel (1) is formed as a large-diameter vessel section (1a) and employed as a reagent introducing section; the lower section of the analysis vessel is formed as a small-diameter vessel section (1b) and marked with reading graduations for reading the liquid level boundary; a lid (3) is provided on the upper end of the large-diameter vessel section (1a); and a biodiesel-fuel-blended light oil and a reagent (A), or neat FAME and a reagent (B), are introduced, the lid (3) is closed, the vessel is shaken and left still for a given period of time, and then the liquid level boundary is read off by using the reading graduations marked on the small-diameter vessel section (1b).
