Abstract

The experiments for China Ⅵ diesel and blended fuel mixed with different components of coal liquefaction were respectively conducted on the XUD-9 bench. The test results showed that the nozzle air flow loss rates for blended and pure fuel were 72.36% and 85.93% respectively without any detergent, were 21.36% and 67.32% after adding the same amount of retaining detergent and were 12.25% and 19.23% after adding the cleaning detergent. In addition, the sensitivity of coal liquefaction mixing diesel to detergency was superior to that of China Ⅵ diesel with the increase of addition after adding different grades of retaining detergent.

Key words
