一、21世纪为何是大然气世纪? 为何说下世纪是天然气世纪,原因有三:一是从能源家族发展史上看,早期薪柴是能源家族中的老大,1920年煤成为老大,1980年石油又替代了煤的位置,预计2020年天然气将成为能源家族中的老大,从世界平均而言,天然气在一次能源构成比中将超过石油,故21世纪世界能源将进入天然气时代;二是环境质量的要求,天然气燃烧造成的污染较小,大体为石油的四十分之一,为煤的八百分之一。特别是我国,一直以煤为主要能源(75%),大气污染十分严重,我国的持续发
First, the 21st century why the great natural gas century? Why the next century is the natural gas for three reasons: First, from the energy family history point of view, the early firewood is the eldest of the energy family, coal became the boss in 1920, 1980, oil And replace the location of coal, natural gas is expected to become the eldest of the energy family in 2020, from the world on average, natural gas in the primary energy composition will exceed the oil, so the 21st century world energy will enter the natural gas era; second environmental quality The pollution caused by the combustion of natural gas is relatively small, which is roughly one-fortieth of the oil and one hundredth of the coal. Especially in our country, coal has been the main energy source (75%) and the air pollution is very serious. Our country’s sustained development
