Natural gas is primarily___. A、ethane B、propane C、methane 点击查看答案
Natural gas is a nonrenewable resource because it cannot be replenished on a human time frame. Natural gas is a hydrocarbon gas mixture consisting primarily of methane, but commonly includes varying amounts of other higher alkanes and sometimes a usually lesser percentage of carbon dioxide, ...
Natural gas is a colorless, odorless, flammable gas that occurs naturally along with petroleum deposits in marshes or from waste decomposition and is composed mainly of methane. The gas can be liquefied for transport and storage and is primarily used as fuel. View all Uses Petroleum gas, ...
Natural gas is primarily used for generating heat, for commercial and domestic heating and cooking, or for industrial processes, or in power stations for generating electricity. It is also used in the petrochemical industry, providing an alternative to oil-based feedstocks such as naphtha and gasoi...
As mentioned earlier, natural gas is primarily composed of methane. After the release of methane to the atmosphere, it is removed by oxidation to CO2 and water gradually in the troposphere or stratosphere [146,147]. The lifetime of atmospheric methane is relatively short compared to that of CO...
In 2024, more than 9 billion gallons of propane were delivered to U.S. consumer markets, primarily for residential heating and cooking, with substantial volumes supporting the commercial, industrial, agricultural and transportation sectors. It is a physically complicated business because, unlike electric...
In the Barnett Shale (Texas, USA), a recent study of CH4emissions from natural gas infrastructure found that emission estimates derived primarily from facility/site-based measurements agreed within statistical uncertainty with basin-level CH4emissions estimates based on aircraft measurements of air column...
Degradation of the world's natural resources by humans is rapidly outpacing the planet's ability to absorb the damage, a recent UN environmental study has found. The study concludes that without radical action the level of prosperity that millions of people in the developed world count on will ...
propane, and butane, changes the average stoichiometric composition for natural gas, with water vapor removed to 0.79 CH3.62. Formed by the same processes that formed oil, natural gas is often found at the top of oil deposits. The most voluminousnatural gas reservoirsoccur in Cretaceous strata....
Compressed natural gas (CNG), a volatile gas, is used to fuel internal-combustion engines. Before use, CNG is processed to remove contaminants as well as other useful fuels such as butane and propane. Natural gas is obtained mainly by drilling underground deposits and is often found with petro...
