MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517067065 A) filed by Basf Se, Ludwigshafen am Rhein, Germany, on July 14, for 'manufacture of an ethylene-derived chemical of interest in combination with production of thermal energy.'
Inventor(s) include Willersinn, Stefan; Weinel, Christian; Keck, Daniel; Rahn, Dieter; and Eller, Johannes Lazaros Friedrich.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "A process for the manufacture of a chemical of interest comprises subjecting a feedstock comprising a renewably-sourced ethanol to dehydration to produce a renewably-sourced ethylene stream, which is subjected to an olefin-interconversion to obtain one or more renewably-sourced C3-4-olefins, selected from propylene, n-butenes and isobutene. Further, the renewably-sourced C3-4-olefin is subjected to a chemical conversion or sequence of chemical conversions to obtain the chemical of interest, the chemical conversion or sequence of chemical conversions producing one or more crude product streams and, optionally, one or more crude intermediate product streams. Subsequently, at least one of the crude product stream(s) and optional intermediate crude product stream(s) is subjected to purification producing one or more purified product streams, one or more waste streams and, optionally, one or more purified intermediate product streams. Then, at least one of the waste streams is incinerated to produce thermal energy. The process provides a reaction scheme that provides renewably-sourced ethylene-derived chemical of interest, while minimizing both fossil carbon dioxide emissions and consumption of renewably-sourced feedstock."
The patent application was internationally filed on Dec. 18, 2023, under International application No.PCT/EP2023/086355.
