MUMBAI, India, Aug. 22 -- Intellectual Property India has published a patent application (202517053539 A) filed by Basf Catalysts Germany Gmbh, Hannover, Germany, on June 2, for 'method and device for obtaining high-purity hydrogen from methanol or ammonia.'

Inventor(s) include Henschel, Carsten; and Machhammer, Otto.

The application for the patent was published on Aug. 22, under issue no. 34/2025.

According to the abstract released by the Intellectual Property India: "The invention relates to a method for obtaining hydrogen from methanol or ammonia. The invention is characterized in that in a first step, methanol or ammonia is evaporated; in a second step, the methanol or ammonia is reformed in order to form a hydrogen-containing gas mixture; in a third step, the gaseous reformate is cooled to 25 to 100 C; in a fourth step, the hydrogen is separated from the cooled gaseous reformate by means of a sorption process at a pressure of 1 to 60 bar and at a temperature of 25 to 100 C; in a fifth step, air is compressed and preheated in parallel with the first four steps; in a sixth step, the adsorbent loaded with the extract is regenerated using the pre-heated ambient air; and in a seventh step, the extract separated from the adsorbent, the tail gas, is combusted using the air. The combustion gases are guided via at least two different heat exchangers, in order to (i) first provide the reaction heat for reforming the methanol or the ammonia and (ii) subsequently provide the evaporation heat for evaporating the reformer feed in the flow direction of the combustion gases. The reformate pre-heats the ambient air for the regeneration process in a heat exchanger prior to entering the sorption step, the separated hydrogen pre-heats the ambient air for the regeneration process after the sorption process, and/or the combustion gases finally pre-heat the ambient air for the regeneration process as step (iii)."

The patent application was internationally filed on Dec. 20, 2023, under International application No.PCT/EP2023/086965.
