Process for producing lube base oils of high viscosity index and diesel oil of high cetaned number |
摘要 |
A process is described for the hydroisomerization/hydrocracking of paraffinic streams to yield lube oils of viscosity index of at least 105 and pour point -6 DEG C. or less, whereby a paraffinic feed which is enriched in iso-paraffins is submitted to hydrogenation in a bed made up of HDM, HDT, HDI/HCC and HDF catalysts, the product oil is separated by distilling the light fractions eventually present and dewaxed to remove the non-reacted high melting point paraffins. Equally considered is a variation in the process whereby diesel oil of high cetane number is produced by recirculating the 370 DEG C.+ cut to the process feed.
