Patent number: 12157094Abstract: New carbon nanomaterials, preferably titanium carbide-derived carbon (CDC) nanoparticles, were embedded into a polyamide film to give CDC/polyamide mixed matrix membranes by the interfacial polymerization reaction of an aliphatic diamine, e.g., piperazine, and an activated aromatic dicarboxylate, e.g., isophthaloyl chloride, supported on a sulfone-containing polymer, e.g., polysulfone (PSF), layer, which is preferably previously prepared by dry/wet phase inversion. The inventive membranes can separate CO2 (or other gases) from mixtures of CO2 and further gases, esp. CH4, based upon the generally selective nanocomposite layer(s) of CDC/polyamide.Type: GrantFiled: March 15, 2024Date of Patent: December 3, 2024Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Isam H Aljundi, Abdelrahman M Awad
