An issue with conventional first-generation biodiesels fuels, in which waste cooking oil is converted into fatty acid methyl ester (FAME), is their poor suitability for recent new model diesel vehicles. To solve this problem, development trials on second-generation biodiesel fuel (bio light oil) were carried out by the Advanced Science, Technology & Management Research Institute in KYOTO as part of an industr y-academia-government collaboration for 3 years from 2012.
It was confirmed that the addition of hydrogen to the cracked oil obtained by high-temperature catalytic cracking of waste cooking oil, converted the raw material to hydrogenated oil, with properties such as oxidation stability that were significantly improved compared with FAME, and with characteristics comparable to light oil fuel. Test drives showed its suitability for use in vehicles and it can be said that "bio light oil", a high-quality fuel equivalent to light oil regarding performance and reliability, was successfully produced.
In this paper, we describe the detailed analysis and evaluation of fuels produced by these methods to promote smooth utilization of waste oil.
