Precious Metal-Free Catalyst for Exhaust Gas Purification of CO2-Neutral Biomethane Engines through Oxidation of HCHO and CH4

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

This patent describes a catalyst for purifying exhaust gases from carbon-neutral biomethane engines. The catalyst is platinum group metal-free and primarily contains α-Fe2O3, which helps convert methane (CH4) and formaldehyde (HCHO) into harmless carbon dioxide (CO2) and water (H2O).

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

• Emission control systems in vehicles powered by carbon-neutral biomethane
• Industrial exhaust gas purification in facilities using biogas or similar fuels
• Power plants using biomethane as a fuel source seeking greener emission solutions
• Retrofit kits for cleaner agricultural or waste-to-energy engines

BenefitsContent extracted from patent full text and abstract with AI.

• Does not use expensive or rare platinum group metals, reducing costs and material sourcing concerns
• Enables effective removal of methane and formaldehyde, both potent pollutants, from engine exhaust
• Supports the use of sustainable, carbon-neutral fuel sources like biomethane
• Contributes to cleaner air and reduced greenhouse gas emissions
