Existence of CH4 Methane

1. CH4 Methane is the main component of natural gas, biogas, oilfield gas, and coal mine gas. The main component of combustible ice is methane hydrate.

2. The volume fraction of methane in natural gas is generally 80% to 97%. The "gas" in my country's "West-East Gas Transmission" refers to natural gas.

3. The main component of gas that causes gas explosions in general coal mines is methane.

Physical properties of CH4 Methane

Under normal circumstances, methane is a colorless, odorless gas with a lower density than air and is extremely difficult to dissolve in water.

Chemical properties of CH4 Methane

1. Stability

Under normal circumstances, methane is relatively stable and does not react with strong oxidants such as potassium permanganate, nor with strong acids or strong bases.

2. Oxidation reaction-flammability

Methane is a flammable gas. The purity must be tested before ignition to prevent explosion accidents.
