The non-hydrogenation refining techniques and its application for RFCC diesei oil
The RFCC diesel fuel is refined by the non-hy-drogenation techniques. The experimental results show that the additive of little phenol or amine substance in the oil product can inhibit the chain reaction of the free radical. Some activated solid substances can adsorb basic nitride effectively. Furthermore, the impurities containing nitrogen and sulfur can be extracted using polar solvent. Four kinds of non-hydrogenation techniques are proposed. The diesel fuels refined by the non-hydrogenation techniques can meet the requirement of the national standard GB252-2000.
