Abstract: The present invention discloses a homo-polymeric and co-polymeric wax inhibitor (WI) useful for the flow of waxy crude oil and their synthesis thereof. The WI(s) comprises of any one of C14 to C24 fatty alcohol or mixture thereof in 2 mol % to 50 mol %, and an unsaturated organic acid i.e. acrylic acid, and poly alpha olefins i.e. poly alpha hexene, poly alpha octene, poly alpha decene, poly alpha dodecene of composition ranging from about 0.01 wt % to 20 wt % wherein the average molecular weight of poly alpha olefins used ranged from 1000 to 10000. A method of preparing a series of WI(s) with varying compositional ratios of the fatty alcohols, acrylic acid and polyalpha olefins targeting a wide range (C17 to C65 or beyond) of wax present in waxy crude oil is also disclosed.

Abstract: A copolymer, poly(thiophene-co-benzothiophene-co-dibenzothiophene), and method of preparation thereof. The copolymer, poly(thiophene-co-benzothiophene-co-dibenzothiophene), having a formula (I): wherein x=H or R, y=H or R, z=H or R, and n=500-58000, wherein R is selected from alkyl or alicyclic chain substituents, and Ar is an aromatic ring.

Abstract: A method for desulfurizing crude oil and sulfur rich petroleum refinery fractions is disclosed. The method includes feeding the crude oil and sulfur rich petroleum refinery fractions to a reactor. An oxidation catalyst is added to the crude oil and sulfur rich petroleum refinery fractions. The crude oil and sulfur rich petroleum refinery fractions and the oxidation catalyst are stirred to form co-polymers of sulfur-containing heterocyclic compounds. The co-polymers of sulfur-containing heterocyclic compounds are separated by filtration or by centrifugation.

Abstract: The present invention discloses a Double Metal Cyanide (DMC) catalyst(s) useful for the production of polyether polyols (PEPO) and a less energy intensive room temperature method for the synthesis thereof. The catalyst(s) comprises of a DMC complex, an organic complexing agent, i.e., ethylenediaminetetraacetic acid (EDTA) and other co-complexing organic agents, e.g., t-BuOH, PEPO of composition ranging from about 1 to 10 wt %, wherein the average molecular weight of PEPO used ranged from 200 to 1000. A method of preparing a series of DMC catalyst(s) at room temperature with varying compositional ratios of the complexing and co-complexing agents targeting a wide range of PEPO of varying kinematic viscosity range is also disclosed. These DMC catalyst(s) are amorphous, highly active, and easily separable from product PEPO with recyclability/recoverability, making the product PEPO better industrially applicable and DMC catalyst more cost-effective.
