烯烃是现代化学工业的基石。随着国民经济的持续快速发展,我国对烯烃的需求量日益增加。近年虽然国内烯烃产业发展很快,但仍无法改变需要大量进口的状况。因此,有识之士认为,我国在加快发展石油烯烃的同时,应加快非石油烯烃的步伐。我国石油资源短缺,在一定程度上限制了以石化路线生产乙烯和丙烯产品的发展。由于国内炼油行业布局分散和平均规模较低,炼厂生产的石脑油数量有限,难以 Olefins are the cornerstone of the modern chemical industry. With the sustained and rapid development of the national economy, the demand for olefins in our country is increasing day by day. In recent years, although the domestic olefin industry has developed rapidly, it still can not change the situation that requires a large amount of imports. Therefore, people of insight believe that while accelerating the development of petroleum olefins, our country should speed up the pace of non-petroleum olefins. The shortage of oil resources in our country limits to a certain extent the development of ethylene and propylene products based on petrochemical routes. Due to the scattered layout of domestic refineries and the relatively low average size, the naphtha production by refineries is limited and difficult to handle
