Technology Development of Ethylbenzene Production from Catalytic Dry-Gas

催化干气制乙苯是利用石化副产干气中的乙烯与苯反应生产乙苯的过程,经过20多年的发展与创新,我们相继开发了具有自主知识产权的干气制乙苯第一代至第五代技术,并在石化行业得到了广泛应用.本文从工艺角度综述了催化干气制乙苯的技术发展历程.

Ethylbenzene production from catalytic dry-gas is a reaction of benzene alkylation with dilute ethene in catalytic dry-gas. For more than 20 years, the technology of ethylbenzene production from catalytic dry-gas, possessing independent intellectual property rights, has been invented and developed from the first to the fifth generation and widely applied in the petrochemical industry of China. In this article, the technology evolution of the ethylbenzene production from catalytic dry-gas is reviewed.
