MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202511120440 A) filed by Harjinder Singh Cheema; J. P. Kundra; Mehar Cheema; and Sahej Kaur Cheema, Mohali, Punjab, on Dec. 2, 2025, for 'a process intensification system for low-temperature methanation of carbon dioxide.'
Inventor(s) include Harjinder Singh Cheema; J. P. Kundra; Mehar Cheema; and Sahej Kaur Cheema.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The invention provides an energy-efficient Process Intensification System for converting carbon dioxide and hydrogen into synthetic methane at approximately 60 C and moderate pressure (3-5 bar). Using a nanobubbler to generate high-pressure hydrogen and carbon dioxide nanobubbles, the system enhances gas-liquid mass transfer and reaction kinetics. The nanobubbles enter an isothermal fixed-bed reactor packed with Raney nickel catalyst and equipped with embedded helically coiled tube heat exchangers for uniform temperature control. A tangential inlet gas-liquid cyclone separator separates high-purity methane from water vapor. This integrated system achieves superior methane yield and conversion efficiency compared to conventional high-temperature methanation, with reduced energy consumption and simplified reactor design. The invention is suitable for sustainable fuel production and Power-to-Gas renewable energy storage applications."
