The present world refinery capacity is estimated at about 3600 million tons per year. The light oil yield in developed countries is above 65%. The world average percentage of oil used in the production of chemicals is about 7-8%. In 1985 the total world ethylene production was 63.95 million tons. The present development of the world petrochemical industry can be characterized with the following features: (1) Distribution tends to be rationalized and plant size optimized.

The present world refinery capacity is estimated at about 3600 million tons per year. The light oil yield in developed countries is above 65%. The world average percentage of oil used in the production of chemicals is about 7-8%. In 1985 the total world ethylene production was 63.95 million tons. The present development of the world petrochemical industry can be characterized with the following features: (1) Distribution tends to be rationalized and plant size optimized. (2) Utilization of resurces tends to rationalize and processing goes deeper and depper. (3) The petrochemical industry is now on the process of shifting from energy consumming industry to energy saving industry. (4) The catalysis technology is becoming more and more effecient. (5) The pollution of environment is in principle under control. It is estimated that the present drop of oil price will be generate a new impaet on the development of the petrochemical industry.

目前,世界每年炼油能力约达36亿吨,发达国家的轻油收率达65%以上。世界化工用油比例平均为7~8%,1985年世界乙烯总生产能力为6,395万吨/年。当前世界石油化工发展水平具有五个特点:(1)布局趋于合理化,规模趋于最佳化;(2)资源趋于合理利用,加工趋于深度化;(3)石油化工正从耗能型转变为节能型的产业部门;(4)催化技术高效化;(5)环境污染基本得到控制。预计,当前的油价下趺,将对石油化工的发展产生新的影响。

In a semi-continuous apparatus, Dayan lignite is extracted with water under sub-and supercritical states. The experiments are carried out to investigate effects of the pressure and the final temperature on the extraction yields, and product components. The results indicate that high conversion and extract yield can be obtained by supercritical water extraction of lignite on appropriate conditions. With the increase of the pressure the conversion and the extract yield increase; With the increase of the final...

In a semi-continuous apparatus, Dayan lignite is extracted with water under sub-and supercritical states. The experiments are carried out to investigate effects of the pressure and the final temperature on the extraction yields, and product components. The results indicate that high conversion and extract yield can be obtained by supercritical water extraction of lignite on appropriate conditions. With the increase of the pressure the conversion and the extract yield increase; With the increase of the final temperature the conversion also increases, but the increment is mainly gas and light oil. The main fraction in extract is preasphaltene, and the main gas component is CO2. The extraction residue is a good feedstock for gasification or combustion.

在半连续实验装置上,以水为溶剂对大雁褐煤进行了超临界萃取实验。考察了压力、终温对萃取过程产率及产品组成的影响。结果表明,用水萃取褐煤在合适条件下,可得到高的转化率及萃取物产率;萃取压力增加,转化率和萃取物产率增加;萃取终温增加,转化率增加,但增加量主要为气体和轻油组分。在超临界条件下,萃取物主要馏分为予沥青烯。萃取过程中气体产率约为20%,其主要组分为CO2;经萃取后的褐煤(约占原煤50%),具有比原煤高的碳含量,低挥发分及氧含量,几乎不含水,可作为气化或燃烧的原料。
