乙烯、丙烯等低碳烯烃是重要的基本有机化工原料,也是现代化学工业的基石。但是,它的传统生产技术强烈地依赖于石油资源,传统上我国一直用石脑油催化裂解制烯烃。随着社会经济的发展,中国在乙烯、丙烯方面的市场缺口逐年扩大,市场前景非常广阔。但我国原油对外依存度不断提高,限制了石油路线生产烯烃的发展。
Low-carbon olefins such as ethylene and propylene are important basic organic chemical raw materials and are also the cornerstone of the modern chemical industry. However, its traditional production technology is strongly dependent on petroleum resources. Traditionally, China has been cracking naphtha with naphtha to produce olefins. With the social and economic development, China’s market gap in ethylene and propylene has expanded each year, and the market prospect is very broad. However, China’s dependence on foreign crude oil continues to increase, limiting the development of olefins production line.
