Wax hydroisomerization process

摘要: This invention discloses a process for producing high Viscosity Index lubricant having VI of at least 125 from waxy hydrocarbon feed wax content 40 wt.%. The comprises catalytically dewaxing paraffins present in the by isomerization presence hydrogen and low acidity large pore zeolite catalyst. catalyst has ratio SiO2/Al2O3, as synthesized, 200:1, wherein is prepared absence boron. may be hydrocracked prior to with zeolite. effluent also further dewaxed either solvent or catalytic means order achieve target pour point.
