Intellectual Property India Publishes Patent Application for 'Preparation Method For Hydropyrolysis Catalyst With Higher Density; Biomass Hydropyrolysis Process Using Obtained Catalyst' Filed by Shell Internationale Research Maatschappij B. V.

MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517061714 A) filed by Shell Internationale Research Maatschappij B. V., The Hague, Netherlands, on June 27, for 'preparation method for hydropyrolysis catalyst with higher density; biomass hydropyrolysis process using obtained catalyst.'

Inventor(s) include Joshi, Rikeshchandra Sharadchandra; Vander Hoogerstraete, Patrick; Roose, Milos; Verschelde, Tom; Grisafe, David Anthony; and Ganji, Santosh.

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: "The present invention provides a method of preparing a hydropyrolysis catalyst, said process comprising the steps of: i) forming a slurry comprising alpha alumina, an alumina precursor, a binder and water; ii) performing spray granulation of said slurry to prepare solid catalyst or carrier spheres; and iii) drying the catalyst or carrier spheres and then calcining them at a temperature in the range of at least 450 C and no more than 900 C, wherein active species comprising a molybdenum and a metal selected from those in groups 8, 9 and 10 of the periodic table are incorporated into the hydropyrolysis catalyst, either by incorporating a molybdenum source and a source of a metal selected from those in groups 8, 9 and 10 of the periodic table into the slurry in step i) or by impregnating the calcined carrier spheres with a solution comprising a molybdenum source and a source of a metal selected from those in groups 8, 9 and 10 of the periodic table and subsequently drying and then calcining at a temperature in the range of at least 450 C and no more than 900 C the thus-impregnated carrier spheres to provide the hydropyrolysis catalyst. The present invention also provides a biomass hydropyrolysis process with the obtained catalyst."

The patent application was internationally filed on Jan. 10, 2024, under International application No.PCT/US2024/010961.
