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

Phosphorous-free oil soluble molybdenum complexes as high temperature fouling inhibitors

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.

Anti-fouling compositions for use in crude oil production and processing

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

Oil soluble molybdenum complexes as high temperature fouling inhibitors

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.

Asphaltene-inhibiting method using aromatic polymer compositions

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.

Carbon products derived from lignin/carbon residue

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 Tlignin. Mixing the reduced Tlignin 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 Tlignin. Mixing the reduced Tlignin 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 Tof a lignin material, thereby forming a reduced Tlignin. Mixing the reduced Tlignin with a carbon residue, thereby forming a fiber precursor mixture and spinning the fiber precursor mixture into a fiber.

Process of making carbon fibers derived from lignin/carbon residue

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.
