A qualified paraffin diluent was prepared by the desulfurization raffinate oil as the feedstock through aromatics hydrocarbon saturation using a metal hydrogenation catalyst.The experiment of aromatic hydrocarbon saturated more than 1000 hour long period has carried on with the catalyst, The result showed that the catalyst chose had the good active stability.The catalyst prepared by the diluent sample was used in the polymerization experiment, the measure results indicated the efficiency of catalyst and the properties of the polyethylene product were similar to using the import diluent, the prepared diluent could completely meet the requirements of polyethylene production.
