One-step Processes for the production of methanol developed recently include partial oxidation, photochemical conversion with steam and direct photoelectric conversion etc., Among them the partial oxidation is commercially competitive with gasoline production, and its production cost is 20% lower than that of the present two-step processes. Compared with two-step processes the direct photoelectric conversion does not require high temperature, high pressure and catalyst and the energy consumption and production...

One-step Processes for the production of methanol developed recently include partial oxidation, photochemical conversion with steam and direct photoelectric conversion etc., Among them the partial oxidation is commercially competitive with gasoline production, and its production cost is 20% lower than that of the present two-step processes. Compared with two-step processes the direct photoelectric conversion does not require high temperature, high pressure and catalyst and the energy consumption and production cost are lower. Therefore the above-mentioned two processes are worth paying attention to.

近年来,一步法制甲醇有部分氧化法、光化学蒸汽转化法和光电化学结合的直接转化法等,其中部分氧化法在经济上能与汽油生产相竞争,成本比目前的两步法低20%;光电化学结合的直接转化法与两步法相比,不需要高温、高压和催化剂,能耗和成本都较低。这两种方法都值得重视。

China has become one of the largest gasoline production and consumption countries in the world with an annual motor gasoline output of more than 20,000,000 tons. However, the nationwide civil automobile population is only 6,000,000 plus, of which the proportion of trucks is high, the compres- sion ratio is low and the gasoline consumption level is 20~30% higher than foreign countries.

China has become one of the largest gasoline production and consumption countries in the world with an annual motor gasoline output of more than 20,000,000 tons. However, the nationwide civil automobile population is only 6,000,000 plus, of which the proportion of trucks is high, the compres- sion ratio is low and the gasoline consumption level is 20~30% higher than foreign countries. The petroleum resource in China is limited, the domestic gasoline market has long been short of supply, and the development of automobile is constrained by energy resources. By speeding up the upgrading of gasoline and by increasing the compression ratio to adopt high octane gasoline will result in a saving of at least 700,000~800,000 tons of gasoline per year. Accordingly, 5 different schemes for the up- grading of gasoline are suggested. After primary analysis and comparison and discussions in the Coor- dination Committee of Automobile and Automotive Oil Products, it is believed the scheme No. 2, i. e. to increase the proportion of premium gasoline to 70~80% by 1993 and to completely change over to premium gasoline by 1995, is probable to realize.

目前我国车用汽油年产量已超过20.0Mt,成为世界汽油生产和消费大国之一,但全国民用汽车保有量仅600多万辆,载重车比例大,压缩比低,油耗水平比国外高约20~30%。我国石油资源有限,市场油品供应长期紧张,汽车发展受能源制约。加速汽油质量升级,提高汽车压缩比使用高辛烷值汽油一年至少可节油700~800kt。设想了“八五”期间汽油升级的5种不同方案。通过初步测算和分析比较,经汽车与汽车用油材料发展协调委员会讨论,认为力争实现方案2的目标是可能的,即1993年高标号汽油的比例将达到70~80%,1995年实现车用汽油的全面升级换代。

The fact that the consumption of high grade and unleaded gasoline has been proportionally increasing has become a main trend in automotive fuel marketing in the world . Based on a vast amount of information and data,this paper describes the surveys in the consumption, quality and new quality specifications of overseas automotive gasoline in detail, Meanwhile it presents the current situation of production, use ,as well as the developing prospects of domestic automotive gasoline.

优级汽油和无铅汽油消费比例上升,是目前世界车用汽油消费的主要倾向。本文论述了国外车用汽油的消费概况、质量水平和新的质量标准,同时介绍了国内车用汽油的生产和使用现状及其发展前景。
