AI Technical Summary
Existing methods for producing fuel gas with high methane content struggle to effectively reduce hydrogen and carbon dioxide concentrations without requiring high-pressure conditions or expensive facilities, leading to safety issues, decreased calorific value, and increased production costs.
A two-step process involving a methanation reaction with a first catalyst followed by an exothermic reaction with alcohols, olefins, or oxygen to convert excess hydrogen into paraffins or water, using catalysts like palladium or platinum on solid acids or inorganic oxides to reduce hydrogen concentration and maintain carbon neutrality.
The method achieves fuel gas with reduced hydrogen and carbon dioxide concentrations, maintaining high calorific value and carbon neutrality, without the need for extreme pressures or additional facilities, thus improving safety and cost-efficiency.
