Embodiment Construction

[0020] The process of the present invention first uses a low-severity hydrocracker to process a waxy feed heavier than distillate fuel into a lower turbidity and / or freezing point distillate fuel, and converts heavy isoparaffins suitable for dewaxing The stream is processed either catalytically or by solvent extraction to low pour point isoparaffinic base stocks of exceptionally high viscosity index and low volatility.

[0021] Feeds useful in the process of the present invention are typically characterized as broad boiling range petroleum derived feeds including: heavy gas oils containing about 50% by weight components boiling above 371°C [700°F] or Contains vacuum gas oils boiling in the range between about 316°C [600°F] and about 566°C [1050°F]. Alternatively, the feed may be all or part of the product from synthesis, eg Fischer-Tropsch synthesis.

[0022] In one embodiment of the present invention, the method for improving feed quality is integrated with Fischer-Tropsch s...

Abstract

A process utilizing a low severity hydrocracker prior to a high severity hydrocracker for the processing of petroleum based and synthetic hydrocarbon feedstocks into distillate fuels and high quality lubricant base oils. The process minimizes the size and conditions required by the high severity hydrocracker by closely matching such configuration with the desired product slate.

Description

[0001] Cross-references to relevant applications [0002] This application claims priority to Provisional Application No. 60 / 536,960, filed January 16,2005. [0003] Federally Sponsored Research [0004] not applicable. [0005] Reference Microfiche Annex [0006] not applicable. technical field [0007] The present invention relates to a process for producing distillate fuels and lubricants in a single facility. The invention also relates to an integrated plant for carrying out the method of the invention. Background technique [0008] As the world supply of crude oil decreases, refiners must use lower-quality crude oil to make high-quality lubricant base stocks. A high quality lubricant base oil is a high quality lubricant base oil with a high viscosity index ("VI"), ie VI > 135, low volatility and low pour point. Severe hydrotreating conditions are required to convert low quality crude oils into high quality lube oils due to the presence of relatively high levels...
