Zhong Hongjun (Research Institute of Jingmen Petrochemical Complex,Jingmen 448039)
Single stage hydrofining of vaseline with reactors in series was researched by the matching technology of special catalysts RG 1/RJW 2 for wax hydrofining at the designed operating conditions. In three schemes of major soft wax as feedstock, the high quality vaseline can be produced to meet the specifications of the standards GB 1790 94 and SH0008 90 for medicinal and cosmetic vaselines. Obvious economic and social benefits were obtained.
