Patent granted for layered double hydroxide catalyst for co2 hydrogenation
A recently granted patent (Publication Number: US11993519B2) discloses a layered double hydroxide formula (I) comprising a mixture of divalent cations including Cu2+ and Zn2+, along with trivalent cations such as Ga3+ and optionally Al3+ or Y3+. The patent further specifies variations in the composition of cations, anions, and solvents used in the preparation of the layered double hydroxide, offering flexibility in the synthesis process. Additionally, the patent covers a thermally-treated form of the layered double hydroxide and a method for preparing methanol through the hydrogenation of carbon dioxide and/or carbon monoxide using the catalyst derived from the layered double hydroxide.
Moreover, the patent outlines a detailed process for the preparation of methanol involving the reduction of the thermally-treated layered double hydroxide to form a catalyst, which is then utilized in the hydrogenation reaction with carbon dioxide and/or carbon monoxide. The temperature range for this process is specified between 200-350°C, ensuring optimal conditions for the catalytic conversion. The patent also emphasizes the importance of Cu dispersion and loading in the catalyst, with specific percentages provided for achieving desired catalytic activity. Overall, the patent offers a comprehensive approach to the synthesis of layered double hydroxides and their application in methanol production through a well-defined catalytic process.
