1.甲烷、天然气和沼气甲烷甲烷的分子式是 CH_4,它是天然气。沼气和煤气等的主要成分之一,属最简单的有机化合物。其特征是无色、无味且难溶于水。当它和空气成适当比例混和时,遇到火花就会发生爆炸。它的化学性质相当稳定,但在适当条件下,会发生氧化、热解及囱代等反应。夭然气天然气是蕴藏在地层内的碳氢化合物,是一种可燃烧气体。它主要是低分子量烷烃的混和物,还含有一些氮、二氧化碳和硫化氢等气体。天然气可分为两种,一种为千气,主要成分是甲烷,通常占8。
1. CH4, NATURAL GAS AND Methane The molecular formula of methane is CH_4, which is natural gas. One of the main components of biogas and gas is the simplest organic compound. Its characteristics are colorless, odorless and hardly soluble in water. When it mixes with air in an appropriate ratio, it will explode when it encounters a spark. Its chemical properties are fairly stable, but oxidation, pyrolysis, and chimney reactions occur under appropriate conditions. Natural Gas Natural gas is a hydrocarbon that is contained in the formation and is a combustible gas. It is mainly a mixture of low molecular weight alkanes and also contains some gases such as nitrogen, carbon dioxide, and hydrogen sulfide. Natural gas can be divided into two types, one is 1000 gas, and the main component is methane, which usually accounts for 8.
