Straight-run naphthas of Yumen, Kramayi, Central Szechuan (60-130℃), and Fushuan hydrogenated shale oil (60-120℃) were platformed separately for aromatics in an isothermal reactorcontaining 80 ml. catalyst. The catalyst used in this study was developed at the Research Institute of Petroleum Science, Ministry of Petroleum Industry. Data are presented to show platforming conditions, material balance and product distributions. Aromatic yields on weight basis were 38.5% (Yumen), 31.8% (Kramayi), 46.6% (Central Szechuan) and 32.2% (Fushun) respectively. Byproduct hydrogen yield was 1.7-2.2% (weight basis), liquid yield was 90-94% (weight basis). During 2170 hours catalyst life test, the aromatic yield decreased from 38.8% to 35.4% 80-180℃ straight-run Yumen and Kramayi gasolines for octane improvement were preliminarily investigated. At a yield of 90% (weight basis), debutanized reformed gasoline had a clear octane number of 72 (motor method). The octane number of the feed stock was 44 (motor method).

The petroleum processing industry of China is now fairly founded with a total annual capacity over 100 million tons. 79 million tons of crude oils were processed in 1984──an all-time high record. In confrontation with the fast growing demand of products, the requirement of higher product quality and the rapid change of demand patterns, China's petroleum processing industry needs to rapidly enhance its science and technology capability and to accelerate the technical innovation during the seventh five-year plan. Major efforts should be concentrated on the development of the various deep conversion technologies around catalytic cracking to increase the yeilds of light products, the improvement of the product quality such as increasing the regular gasoline octane level to higher than 90 (RON), speeding up computer applications in processing and management,further improvement of energy conservation, expending the current crude capacity and the rational utilization of oil resources for the production of petrochemicals.

我国石油加工工业已有相当基础,年原油加工能力超过一亿吨,1984年实际加工7900万吨原油,创历史最高水平,但是面对产品需求增长,产品质量提高和需求产品结构的变化等新形势,在第七个五年计划期间,中国石油加工工业需要大力发展科学技术,加速技术改造的步伐,重点是发展以催化裂化为主的各种深度加工工艺,增加轻质石油产品收率;提高产品质量,特别是把普通汽油的辛烷值提到90(研究法)以上;加速电子计算机在生产过程和管理方面的应用;降低能耗;扩大原油加工能力以及合理利用原油资源发展石油化工产品等。
