天然气利用现状与展望

天然气作为一种清洁高效的能源，对优化目前燃料结构、提高终端用能效率、减少环境污染起着十分重要的作用。同时，天然气也是一种重要的化工原料，可生产多种化工产品，对国民经济具有重大的经济价值，天然气的加工及利用有着广阔的市场前景。为此，对２０世纪世界范围内天然气工业的发展和天然气的应用作了简要回顾与分析，同时阐述了天然气作为优质环保型燃料和化工原料在我国开发和利用方面的滞后原因及与世界上发达国家的差距，并展望了我国在２０１０年时的天然气加工利用前景。

STATUS QUO AND PROSPECT OF NATURAL GAS UTILIZATION

As one kind of the clean and high efficiency energy source, natural gas plays a very important role in optimizing current fuel constitution, improving terminal energy utilization efficiency and eliminating environmental pollution. It is also an important chemical raw material. It can be used to produce manifold chemical products, having great value to national economy. Thus, natural gas processing and utilization has wide product market. Both develop- ment and application of global natural gas industry in the 20 century were briefly reviewed and analyzed. Meanwhile. the cause of backwardness in developing and utilizing natural gas as superior envioronmental friendly fuel and chemi- cal raw material in China were analyzed and the distinction between China and the advanced countries were pointed out. Prospects for natural gas processing and utilizing in Chin in 2010 were also given.
