摘要:
Organosilica materials, which are a polymer of at least one independent monomer of Formula [Z1OZ2OSiCH2]3 (I), wherein each Z1 and Z2 independently represent a hydrogen atom, a C1-C4 alkyl group or a bond to a silicon atom of another monomer and at least one other trivalent metal oxide monomer are provided herein. Methods of preparing and processes of using the organosilica materials, e.g., for catalysis etc., are also provided herein.
摘要:
The invention relates to a method for analyzing a lubricating oil. The method utilizes 2-dimensional gas chromatography (2D GC) to determine the amounts of paraffins and isoparaffins in the oil. The compositional information thus obtained is used to calculate a paraffin index correlated with formulated oil MRV.

摘要:
Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include at least two zeolites, including a zeolite with a low silica to alumina ratio. The catalysts may be combined with a low surface binder, or alternatively the catalysts as formulated may have a high ratio of zeolite surface area to external surface area.
摘要:
The invention relates to a process for preparing lube oil basestocks from lube oil boiling range feeds. More particularly, the present invention is directed toward a process wherein a wax containing feed is solvent dewaxed to produce at least a partially dewaxed lube oil boiling range stream, which is hydrodewaxed to produce a first lube basestock. The first lube basestock is added to an independently selected second lube basestock and additives to make a lubricating oil.
