Abstract: The stable components of catalytic diesel fuel and the methods of improving its stability have been studied. The pro-duction process of extracting and refining the catalytic diesel fuel by complex solvent has been tested. Results indicate that the yield of refined diesel is over 99% when the ratio of solvent to
oil is 1:500-50:500. After aging, the amount of sediments is less than 2.5mg/100ml and the color of the refined oil is not more than 3.5. The gum and oxidized sediments are reduced by 60.1% and 77.6% respectively. Also the percentage of remov-ing nitrogen and sulfur is 19.8% and 20.3%.

Key words: catalyst, diesel, solvent, refining, technology process
