| titleOfInvention | Method for wax hydroisomerization |
| abstract | (57) Abstract A petroleum wax is converted to a high viscosity index lubricating oil by a synergistic method using two catalysts. Viscosity index and yield are higher for products from the integrated catalyst method than for products using either catalyst alone. A waxy feed that may be pretreated by mild hydrocracking is first reduced in the presence of hydrogen by a preferential isomerization to a high viscosity index isoparaffin with a low wax content of the paraffin component in the feed. Isomerization is carried out by an acidity zeolite isomerization catalyst. The isomerization operation is performed at a hydrogen partial pressure (reactor inlet) of at least 5617 kPa abs . The catalyst is preferably a noble metal-containing zeolite beta catalyst containing boron as the framework component of the zeolite so as to obtain a low alpha value, typically an alpha value of 20 or less. The isomerization is carried out at a temperature of 345 ° C. with a conversion in the range from 10 to 40% by weight of the feed. Subsequently, the product of the isomerization process is contacted with a shape-selective catalyst to further reduce the pour point. Preferably, ZSM-22, ZSM-23 or ZSM-35 is used. The shape-selective catalyst preferably comprises a noble metal, such as Pd or Pt. |
