Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.

2024年11月12日 · Methane, colorless, odorless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases.

Methane Basics. Methane (CH 4) is a powerful greenhouse gas, and is the second-largest contributor to climate warming after carbon dioxide (CO 2). A molecule of methane traps more heat than a molecule of CO 2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere, while CO 2 can persist for hundreds of years or more.

Methane (a gas composed of carbon and hydrogen) is produced two ways:Through biologic decomposition of organic matter at shallow depths. Swamps, landfills, and even shallow bedrock are some settings where this occurs.

What is Methane? Methane is the simplest of saturated hydrocarbons with a chemical formula CH 4. It consists of four hydrogen atoms and one carbon atom and is the simplest alkane. When natural methane reaches the surface of the atmosphere is called atmospheric methane and can be found under the seafloor as well as below the ground.

2019年1月23日 · Methane's impact on climate, past and future. Methane may also have been the cause of rapid warming events deep in Earth’s history, millions of years ago.

2025年3月3日 · Methane (CH 4) is a hydrocarbon that is a primary component of natural gas. Methane is also a greenhouse gas (GHG), so its presence in the atmosphere affects the earth’s temperature and climate system. Methane is emitted from a variety of anthropogenic (human-influenced) and natural sources.

How is methane used? Methane is the main component of natural gas and is widely used in homes, businesses and factories all over the world. In homes, methane may be used to fuel a water heater, furnace, stove, clothes dryer, etc. In the industrial sector, methane is used as a fuel for gas boilers and turbines. oeeee

2024年7月19日 · Methane (CH4), the primary component of natural gas, is responsible for approximately a third of the warming we are experiencing today.

2025年1月28日 · Methane(CH₄) is a colorless, odorless gas that plays a crucial role in both the environment and the energy sector. It is the simplest form of a hydrocarbon, consisting of one carbon atom bonded to four hydrogen atoms ( CH₄ ).
