A heavy residual petroleum feed boiling above 650&#xb0; F.+ (345&#xb0; C.+) is subjected to hydroconversion at elevated temperature in the presence of hydrogen at a hydrogen pressure not normally higher than 500 psig (3500 kPag) using a dispersed metal-on-carbon catalyst to produce a hydroconverted effluent which is fractionated to form a low boiling fraction and a relatively higher boiling fraction which is subjected to membrane separation to produce a permeate which is low in metals and Microcarbon Residue (MCR) as well as a retentate, containing most of the MCR and metals. The process has the advantage that the hydroconversion may be carried out in low pressure equipment with a low hydrogen consumption as saturation of aromatics is reduced.

The present invention is directed to a method that determines the necessary and sufficient tests to relate a variety of apparently non-related tests to desired final test results. The present invention also provides a method to determine those tests which, having been shown capable to be used in a high-throughput environment, are able to predict end-use qualification test results for lubricants, greases or industrial fluids. As a corollary, the present invention provides a method to select lubricant formulations and components based on apparently non-related, but predictive tests. In an applied example, the present invention is directed to a device and method that produces and evaluates formulated lubricants, functional fluids, and greases by determining previously unknown relationships between Intermediate Tests and End-use Tests.
