Diesel fuel composition for reduced particulate emission

摘要

A diesel fuel composition for reduced particulate emission has a <13>C nuclear magnetic resonance (NMR) spectrum in which the ratio of the total area of a group of peaks with a chemical shift in the range of 33 to 50 ppm with respect to the total area of the group of peaks with a chemical shift in the range of 0 to 50 ppm is equal to or less than 30%, and preferably equal to or less than 20%. The region of the peaks with a chemical shift in the range of 33 to 50 ppm includes peaks due to at least a tertiary or quaternary carbon atom within saturated hydrocarbon portions with a branching structure. This diesel fuel composition has a reduced content of hydrocarbons with a branching structure and aromatic hydrocarbons, and is able to positively reduce the emission of particulate matter.
