MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517058233 A) filed by BP P. L. C., London, on June 17, for 'in-situ treatment of a fischer-tropsch catalyst.'
Inventor(s) include Paterson, Alexander James.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "A process for converting a mixture of hydrogen and carbon monoxide to a hydrocarbon composition comprising one or more optionally oxygenated hydrocarbons, the process comprising the following steps: (a) providing a catalyst material comprising cobalt disposed on a support; (b) reducing the catalyst material at a temperature of below 300 C to form the first activated catalyst; (c) contacting the first activated catalyst with a mixture of hydrogen and carbon monoxide at a first reaction temperature (TR1) of at least 180 C and first reaction pressure (PR1) of at least 10 bara to produce hydrocarbons for a first reaction time period of at least 24 hours; (d) after the first reaction time period, contacting the first activated catalyst with a carbon monoxide rich stream at a first pressure (P1) and a first temperature (T1) to provide a treated catalyst, wherein P1 is at least 1 bara and at most 50 bara, and T1 is at most 300 C; (e) contacting the treated catalyst with a hydrogen rich stream at a second temperature (T2) and a second pressure (P2) to form a second activated catalyst, wherein P2 is at least 10 bara and wherein T2 is less than 300 C; and (f) contacting the second activated catalyst with a mixture of hydrogen and carbon monoxide at a second reaction temperature (TR2) of at least 180 C and second reaction pressure (PR2) of at least 10 bara to produce hydrocarbons."
The patent application was internationally filed on Dec. 01, 2023, under International application No.PCT/IB2023/062142.
