Research Progress in Anti-Coke Coating Technology for Ethylene Cracking Tube

Operating period of ethylene cracking furnace is determined by rate of coking on inner surface of its tube,so study of how to alleviate coking has become a hot topic for ethylene production.The negative effect of coking on ethylene production and coking mechanism were also introduced.Research progress in anti-coke coating technologies was reviewed,including online coating and offline coating technologies.The advantages and shortcomings of the two were compared.Development trend of anti-coke coating technologies and research targets were stated.
