Process for manufacturing lube base stocks |
摘要 |
This invention provides an improved method for manufacturing a slate of lubricant base stocks from a paraffin base or a mixed base crude. In one embodiment of this invention, the bright stock raffinate is catalytically dewaxed with a catalyst comprising ZSM-5, for example, and the neutral oil raffinates are solvent dewaxed. The combined use of solvent and catalytic dewaxing as described herein provides a highly efficient method of manufacture without loss of product quality.
