Publication number: 20240018023Abstract: Copper-boron-ferrite (Cu—B—Fe) composites may be prepared and immobilized on graphite electrodes in a silica-based sol-gel, e.g., from rice husks. Different bimetallic loading ratios can produce fast in-situ electrogeneration of reactive oxygen species, H2O2 and ·OH, e.g., via droplet flow-assisted heterogeneous electro-Fenton reactor system. Loading ratios of, e.g., 10 to 30 wt. % Fe3+ and 5 to 15% wt. Cu2+, can improve the catalytic activities towards pharmaceutical beta blockers (atenolol and propranolol) degradation in water. Degradation efficiencies of at least 99.9% for both propranolol and atenolol in hospital wastewater were demonstrated. Radicals of ·OH in degradation indicate a surface mechanism at inventive cathodes with correlated contributions of iron and copper. Copper and iron can be embedded in porous graphite electrode surface and catalyze the conversion of H2O2 to ·OH to enhance the degradation.Type: ApplicationFiled: January 20, 2023Publication date: January 18, 2024Applicant: King Fahd University of Petroleum and MineralsInventors: Chanbasha BASHEER, Hakimu NSUBUGA

Publication number: 20240011376Abstract: A method for mitigating gas override in an hydrocarbon reservoir by increasing sweep efficiency and consequently improving incremental oil recovery is provided with at least one injection well, at least one production well, and an hydrocarbon reservoir. The injection well and the production well are in fluid communication with the hydrocarbon reservoir. An injection blend produced by mixing a displacement fluid with an organic solvent is transferred into the hydrocarbon reservoir through the injection well. Preferably, the displacement fluid is supercritical carbon dioxide and the organic solvent is triethyl citrate. The higher density and the viscosity of the injection blend are vital in reducing gravity override and improving sweep efficiency. A resulting injection blend is extracted from the production well and the organic solvent is separated. Since the organic solvent can be reused, the method of mitigating gas override can be financially and operationally beneficial.Type: ApplicationFiled: September 22, 2023Publication date: January 11, 2024Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Sidqi A.
