Progress in Coking Model of Tube in Radiation Section of Cracking Furnace

?Ethylene is the most important basic material of chemical industry. Development status of ethylene industry is usually looked upon as the symbol of the level of development of a country's petrochemical　industry.Almost 99 percent of world's ethylene is currently produced by tube steam cracking furnace, however,the yield and on-stream time of cracking furnace is severely restricted by coke formation on tube inner surface. Many scientists have begun to investigate coking ever since the fifties of last century, and have published their research methods and results. Progress of the coking model of tube in radiation section of cracking furnace was carefully reviewed.
