Biodiesel fuel (Fatty acid methyl esters: FAME) shows high boiling temperature, so that it allows to accumulate in the engine oil, causing the premature engine wear. Recently, it was reported that the distillation characteristics of FAME is adjusted to that of petro-diesel fuel by the cross-metathesis reaction with ruthenium catalyst. The purpose of this study is to be clear the influence of the cross-metathesis reaction conditions on distillation characteristics of waste cooking oil methyl ester(WME) and to reveal the reaction condition adjusting to distillation characteristics of petro-diesel fuel. In experiment, the cross-metathesis reaction of WME and 1-hexene with Umicore Grubbs catalyst M51 was carried out at various reaction temperature and molar ratio of catalyst. Form the result, it was found that the oleic acid methyl ester and linoleic acid methyl ester in major component in WME are sensitive to reaction temperature and molar ratio of catalyst. And it was shown that the reaction condition adjusting to distillation characteristics of petro-diesel fuel is 0.24 mol-% in catalyst per WME and 50 degrees Celsius in reaction temperature.
