甲烷

In America, the methane chloridate are all produced by methanol hydrochlorinate; in Europe, there are only three factories to produce methane chloridate by methane chlorination and in Japan, only two factories.

随着甲醇工业的迅速发展，甲醇氢氯化法在经济上和技术上的优势越来越明显，在世界范围内已有后来居上取代甲烷法的趋势。在美国目前甲烷氯化物生产全部使用甲醇法，在欧洲只有3个工厂，日本只有2个厂还在使用甲烷热氯化法。

As for the radius of porous media effect our experiments select four kinds of sea-sand whose pore radius vary between 125-700μm.The results shows that the pore radius we use in the experiments are too large to produce capillary effect which can clag the process of hydrate formation, only if the pore radius is smaller than 60 nm the can produce capillary effect.

基于粒径范围125-700μm的四种多孔介质的甲烷水合物生成实验结果表明，较粗粒径的多孔介质引起的孔隙间毛细作用对甲烷水合物不会产生明显的阻碍作用，但计算结果表明，孔径粒径小于60nm的多孔介质会阻碍甲烷水合物的生成。

Identical data inequilibrium stats and similar shock-induced reacting flow fields are gained for tworeaction models when projectile velocity is 3km/s. In this case, the molar fraction ofdissociated methane is so small that the frozen flow or a very simple reaction modelcan well describe the flow field of weakly shocked methane. As projectile velocityincreases, molecular methane is readily dissociated and some stable products are formed. Only do the numerical results of the 40 reactions involving13 species approach to the corresponding experimental results.

计算表明，当飞片速度低(3km／s)时，两种反应模型给出冲击状态参数的结果基本一致，因为这时甲烷气体冲击波后的成分变化很小，说明可以用更简单的化学反应模型描述高温甲烷的化学反应过程；当飞片速度增大时，甲烷分子迅速的离解，反应产物容易形成稳定的化合物，只有13组元40反应模型的计算结果才能与实验结果接近。

Some examples of existing CDM projects are:installing a waste heat-recovery system into a coking plant; establishing a coal mine methane-utilisation scheme for households currently using coal, and installation of an electricity generation station fuelled by coal mine methane; capturing waste gases (blast furnace gas and coke oven gas) from the steel-making process for utilisation in a new, combined-cycle power plant; constructing a pilot biomass power plant, utilising cotton and corn straw as fuel, to generate electricity to be supplied to the North China grid system; capturing methane from a landfill to produce power for the local grid; establishing wind farms; and reforesting mixed-used forest in Guangxi.
