Abstract: An anti-fouling composition has been developed that provides an advantageous reduction in the fouling of a structural part in a petroleum-refining system including reducing coking reactions and inhibiting deposition of solids in equipment and lines used for crude oil production and processing. The anti-fouling compositions contain a resin comprising an alkyl phenol-aldehyde resin, a polyolefin comprising a polyalkylene ester, polyolefin amide alkeneamine, polyethylene polyamine, polyalkyleneimine, or a combination thereof; and optionally, a polyalkylene imide, an amine-substituted polyalkylene imide, or a combination thereof; and optionally, N,N?-disalicylidene-1,2-propanediamine.

Abstract: Disclosed are molybdenum-containing complexes used in compositions and methods for inhibiting or reducing the deposition of foulant on equipment.

Abstract: The present invention generally relates to nonylphenol-free alkoxylated 4-(alkyloxy)phenol/aldehyde resins and processes for making alkoxylated 4-(alkyloxy)phenol/aldehyde resins. The invention also relates to methods of breaking emulsions of oil and water comprising the dosing of an effective amount of an emulsion breaker composition into a stable emulsion to destabilize the emulsion, wherein the emulsion breaker composition comprises an alkoxylated 4-(alkyloxy)phenol/aldehyde resin.

Abstract: A precursor having at least five percent of lignin based coke and d002 spacing of more than 3.36 angstroms and less 3.44 for making graphite. Methods for making a green/graphite article include mixing coke derived from a petroleum product, a coal product or a bitumen product with coke derived from lignin. Alternatively, the precursor material for the various types of coke may be mixed and coked together. The mixture may be formed into a desired shape. The article may be subsequently carbonized and graphitized. The amount of lignin derived coke comprises a sufficient quantity to change at least a selected property of the graphite article.

Abstract: A method of making a carbon fiber comprising esterification of a lignin precursor with an acid, acid anhydride, or acyl halide, thereby forming a reduced Tg lignin. Mixing the reduced Tg lignin with a carbon residue selected from the group of coal based raw material, petroleum based raw material and combinations thereof, thereby forming a fiber precursor mixture; and spinning the fiber precursor mixture into a fiber. A method of making a carbon fiber comprising esterification of a lignin with an acid derivative, thereby forming a reduced Tg lignin. Mixing the reduced Tg lignin with a pitch, thereby forming a fiber precursor mixture; and spinning the fiber precursor mixture into a fiber. A method of making a carbon fiber comprising lowering the Tg of a lignin material, thereby forming a reduced Tg lignin. Mixing the reduced Tg lignin with a carbon residue, thereby forming a fiber precursor mixture and spinning the fiber precursor mixture into a fiber.

Abstract: A method of making a carbon fiber includes heat treating a lignin precursor absent an active ingredient in an inert atmosphere to raise the glass transition temperature (Tg) of the precursor by at least five (5%) percent, forming a lignin precursor having an increased Tg (High Tg Lignin). The High Tg Lignin can be spun into a fiber. The fiber may then be stabilized to form a thermoset fiber. The time period for stabilizing the fiber is less than one hundred (100) hours.
