A Catalytic Material Comprising Supported Co3mo3n for the Synthesis of Nh3

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a new catalytic material based on Co₃Mo₃N (cobalt molybdenum nitride) promoted with specific alkali metals (like K and Cs) and transition metals (such as Fe, Mn, etc.) for the industrial synthesis of ammonia (NH₃). The catalyst is designed to improve the efficiency of ammonia production, especially under lower temperature and/or pressure conditions than conventional catalysts.

Use CasesContent extracted from patent full text and abstract with AI.

• Ammonia production in chemical plants using the Haber-Bosch process
• Modernization of existing ammonia plants to improve efficiency and sustainability
• Enabling ammonia synthesis with hydrogen derived from renewable sources (green ammonia)
• Industrial applications where lower temperature operation reduces equipment stress and costs
• Production of ammonia as a carbon-neutral fuel or fertilizer precursor

BenefitsContent extracted from patent full text and abstract with AI.

• Higher catalytic activity for ammonia synthesis compared to existing Co-Mo-N catalysts
• Enables ammonia production at lower temperatures and/or pressures, leading to energy savings and lower operating costs
• Reduces CO₂ emissions per ton of ammonia produced, supporting sustainable manufacturing
• Can be implemented as a drop-in solution for existing Haber-Bosch plants
• Good resilience to variable H₂/N₂ ratios, including hydrogen-rich feeds (beneficial for integration with renewable hydrogen)
• Improved catalyst stability and lifespan due to optimized promoter combinations
• Facilitates the transition towards green ammonia by accommodating hydrogen from renewable sources
