Methane

**Chemical Properties and Reactions**:
– Methane is a tetrahedral molecule with four equivalent C-H bonds.
– Primary reactions include combustion, steam reforming, and halogenation.
– Selective oxidation to methanol is challenging due to overoxidation.
– Methane is an extremely weak acid in acid-base reactions.
– Interest in catalysts for C-H bond activation in methane.

**Applications and Uses**:
– Used as a fuel for heating, cooking, electricity generation.
– Feedstock for chemicals like ammonia, methanol for fuel cells.
– Important role in petrochemicals, agriculture, and various industries.
– Used in ovens, homes, water heaters, kilns, and automobiles.
– Major component of natural gas for electricity generation.

**Environmental Impact and Mitigation**:
– Methane is a potent greenhouse gas with higher global warming potential than CO2.
– Contributes to climate change from agriculture, landfills, and fossil fuel production.
– Efforts to reduce emissions through better waste management and capturing from landfills.
– Leaks from natural gas infrastructure contribute to environmental impact.
– Measures taken to reduce methane emissions for climate change mitigation.

**Rocket Propellant and Energy Efficiency**:
– Refined liquid methane and LNG used as rocket fuels with liquid oxygen.
– Methane offers advantages over kerosene in producing small exhaust molecules.
– Easier to store than hydrogen due to higher boiling point and density.
– Increases specific impulse of rockets compared to liquid hydrogen.
– Methane increases kinetic energy available for propulsion.

**Industrial and Renewable Applications**:
– Used in chemical synthesis to produce hydrogen, methanol, and acetylene.
– Feedstock for ammonia, formaldehyde, carbon black production.
– Key component in synthetic natural gas production.
– Renewable energy source from organic waste through anaerobic digestion.
– Capture and utilization from agriculture and waste management for sustainable energy practices.
