苯乙烯是合成材料的重要原料之一,无论是合成橡胶,塑料或树脂,都需要大量的苯乙烯。随着我国化学工业的飞速发展,苯乙烯的需要量日益增加,但是目前苯乙烯的来源依靠于苯的烃化、脱氢等工艺,这就需要消耗大量的苯。我国具有丰富的石油资源,目前我国石油化学工业有了迅速的发展,自石油裂解制乙烯的副产焦油中,就含有丰富的苯乙烯。据报导,对于十万吨规模的乙烯装置而言,
Styrene is one of the important raw materials for synthetic materials. Whether it is synthetic rubber, plastic or resin, a large amount of styrene is required. With the rapid development of chemical industry in our country, the demand of styrene is increasing day by day. But at present, the source of styrene depends on the process of benzene alkylation and dehydrogenation, which consumes a large amount of benzene. China has abundant oil resources. At present, China’s petrochemical industry has enjoyed rapid development. Since the by-product tar from petroleum cracking to ethylene is rich in styrene. It is reported that for the 100,000 ton ethylene plant,
