Consideration for Character of Marine Fuel Based on Fourier Transform Infrared spectrometry

The latest heavy based oil for marine fuel oil tends to become heavier and inferior quality, for catalytic cracker or thermal cracker operates owing to increase of demand of gasoline and gas oil. On the other hand, still there are reports regarding with engine troubles which are caused by inferiority of ignition, combustibility and stability of the marine fuel oil. With regard to ignition and combustibility of marine fuel oil, it is difficult to judge from the results of standard analysis; consequently reports of special analysis of every kind are published. Under such a condition, we found out the knowledge to make sure of combustibility and stability of marine fuel oil by measuring the absorption value on methyl and methylene group which are included in the fuel oil.
