MUMBAI, India, Dec. 13 -- Intellectual Property India has published a patent application (202511027362 A) filed by Indian Institute Of Technology, Jodhpur, Rajasthan, on March 24, for 'metal organic framework (mof) integrated membrane for low viscous oil removal.'
Inventor(s) include Gulshan Verma; and Dr. Ankur Gupta.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a hydrophobic and oleophilic membrane for efficient oil-water separation. The hydrophobic and oleophilic membrane comprising a candle soot decorated carbon nanofiber (CS:CNF) substrate functionalized with amino-functionalized titanium-based (NH2-MIL(Ti)) metal-organic framework nanoparticles. The MOF nanoparticles form a nano-hierarchical structure, imparting selective permeation of oil while repelling water, even at parts-per-million (ppm) water concentrations. The membrane is fabricated via electrospinning, carbonization, and solvothermal MOF growth, producing a thermally stable, high surface area (905 m/g), and 4 nm pore diameter structure. The membrane demonstrates high oil flux, water rejection rate, and multi-cycle durability, validated through gravity-driven and tilted oil-water separation experiments with low-viscosity oils such as diesel, gasoline, and turpentine. Therefore, the present invention provides a cost-effective, scalable, and reusable solution for industrial oil-water separation, offering enhanced separation efficiency and environmental sustainability."
