  • Upgrading of petroleum resid, bitumen, shale oil, and other heavy oils by the separation of asphaltenes and/or resins therefrom by electrophilic aromatic substitution
    Publication number: 20080251418
    Abstract: Heavy, high molecular weight multi ring aromatics present in petroleum resid, bitumen and heavy oils in the form of asphaltenes, heavy resids and polycyclic hetero (N) aromatic molecules are separated from the petroleum resid, bitumen and/or heavy oils, by the process comprising electrophilic aromatic substitution of polar groups onto the heavy high molecular weight multi-ring aromatics thereby rendering them insoluble in and facilitating their separation and recovery from the petroleum resid, bitumen and/or heavy oil.

  • Method to determine predictive tests and device applying same to lubricant formulations
    Patent number: 7392142
    Abstract: 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.

  • Polymers having dihydroxy moieties
    Patent number: 5712231
    Abstract: The present invention provides novel polymers comprising a plurality of dihydroxy aromatic moieties and at least one polyalkyl moiety. In one embodiment of the present invention, the polymer is formed from about 2 to about 50 interconnected dihydroxy aromatic moieties each having an attached polyalkyl moiety. In another embodiment of the present invention, the polymer is represented by the formula A.sub.x P.sub.y where A is an aromatic dihydroxy moiety and P is a polyalkyl moiety. The polymers of the invention are useful as lubricating oil additives.
