摘要
天然气是优质的绿色燃料。用作汽车燃料 ,可明显减少有害气体排放。较之压缩天然气、液化天然气 (LNG) ,具有能量存储密度大、一次充灌行驶里程长的巨大优势。此外 ,低压的 LNG存储在1 1 0 K的低温下 ,因而蕴藏着大量的冷能 ,回收该冷能用于汽车空调或低温冷藏链中的冷藏运输过程 ,这不仅有效回收、利用了能源 ,而且减少了机械制冷造成的大量动力消耗和制冷剂泄漏造成的臭氧层破坏 。
It is in the ascendant to search the new auto replacing fuel in the face of the shortage of the petrol resource and the pollution of the auto exhaust. Natural gas is a green fuel with high quality and abundant reserves in our country. The harmful exhaust will decrease obviously if we use the natural gas as the futo fuel. Compared with the Compressed Natural Gas, Liquefied Natural Gas has the advantages of higher energy intensity and longer running mileage, so it is more suitable for auto fuel. In addition, LNG in cryogenic situation of 110K has plenty of cold energy. The cold energy reclaimed is used in auto air-conditioning or cold transport of cold chain, which has efficiently recovered and utilized energy and has both great economy and environment protection benefit for greatly decreasing power consumption and destruction to ozonosphere.
