  • PROCESS FOR THE PREPARATION OF HIGHER-GRADE VG BITUMENS USING SULFUR-BASED POLYMERIC ADDITIVES (SBPA)
    Publication number: 20240318002
    Abstract: Higher grade VG bitumens are prepared particularly by blending of 0.1 to 20 wt % specific Sulfur-Based Polymeric Additives (SBPA) having MW 1,000 to 10,000 Dalton. The prepared higher grade VG bitumens have Kinematic Viscosity of from 200 cSt to 1000 cSt measured at 135° C. from Base bitumen (VG10) at a temperature from 100° C. to 140° C. and stirring in the range of 800 rpm to 1200 rpm for 30 minutes to 90 minutes for improving the properties of bitumens and to make higher grades of Bitumens (VG20, VG30, VG40) for industrial applications.

  • Method for reactive desulfurization of crude oil and sulfur rich petroleum refinery fractions
    Patent number: 11802249
    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.
