Method for production of lubricating oil base oil by hydrode-waxing

The present invention relates to a method for produciing base oil of lubricating oil by using hydrodewaxing process. The invented hydrodewaxing one-step method is that it uses a vacuum waxy oil distillate of 300-510 deg.C of petroleum raw oil and tail oil obtained from hydrocracking of the above-men...

Zusammenfassung:	The present invention relates to a method for produciing base oil of lubricating oil by using hydrodewaxing process. The invented hydrodewaxing one-step method is that it uses a vacuum waxy oil distillate of 300-510 deg.C of petroleum raw oil and tail oil obtained from hydrocracking of the above-mentioned distillate, and uses a shape-selective catalyst under the condition of pressence of hydrogen, and makes the above-mentioned raw materials don't pass through independent refining process and directly implement hydrodewaxing process. After its reaction product is fractionated, in addition to partial by-products of liquefied gas and gasoline, all others can be used as base oil for making low pouring point lubricating oil.
