This chapter discusses the possible sources of natural gas for France and the ECE area in 1990. In France, the requirements in 1985 were 37 billion m3 according to the goals established by the Planning Council. In 1990, it was expected to be from 42 to 44 billion m3. The discovery and ...
Scientists have been studying natural sources of methane for decades but hadn’t regarded plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. Now Keppler and his colleagues find that plants, from grasses to trees, may ...
Current microbiological processes responsible for sources of natural gas in the lake included pelagic meth- anogenesis and decomposition of terrestrial grasses in the littoral zone. Methanogenesis in the pelagic sediments resulted in methane saturation (2–3 mM at 50 cm; δ13CH4 = about −85%....
A special advantage of natural gas is that it bums very cleanly. When natural gas burns, it produces mostly carbon dioxide and water vapor. Oil's main advantage is that it burns efficiently — meaning that little is wasted in the change to energy. Also, the refining (提炼) process that ...

Question 24Methane gas may be obtained from a number of different sources. It is a major component of natural gas. Methan trapped in coal is called coal seam gas and can be extracted by a process known as fracking. Methane is also produced by the microbial decomposition of plant and ...
14 (Xinhua) -- Emirali Gulmez, a retired Turkish citizen in his late 70s, lives alone in a slum on an always windy and chilly hill of Türkiye's largest city Istanbul. Gulmez's tiny house is equipped with a natural gas heating system to keep him comfortable in the cold winter days,...
解答答案:B.根据后句Coal,natural gas,solar power,nuclear power and even water can replace it as sources of energy.可以知道煤,天然气,太阳能,核能甚至是水都能代替它作为能量的来源,所以前一句应该是科学家已经发现石油作为燃料的替代品,所以选择B substitutes替代品,其他选项与句义不符,A是结果;C是要求;D...
Here Today,Gone TomorrowFossil fuels are sources of energy in the form of coal,oil,and natural gas. These fuels are called fossil fuels because they are formed over millions of years from the fossils,or remains,of dead plants and animals. Eventually the fossils are buried under dirt and rock...
With the increasing demand for energy sources of oil and gas, people should look for sources of oil and gas in remote and untouched places. Do the advantages outweigh the disadvantages of damaging such areas? 1.题目大意 随着对石油和天然气等能源的需求增加,人们应该在偏远和未开发的地区寻...
