%X Recent advances in directly heated cracking using heat carrier gas together with the wide applications in industry are reviewed,focusing on the composition,operating conditions,product yields and the progress of pyrolysis apparatuses of directly heated cracking using heat carrier gas.In addition,the decoking techniques,mechanism and kinetics of hydrocarbons pyrolysis are also summarized up.Finally,the outlook for the future development of directly heated cracking using heat carrier gas is provided and a conclusion is drawn that directly heated cracking using superheated steam produced by combustion of hydrogen and oxygen as heat carrier gas will be one of the most promising techniques for it has the advantages of high feedstock and products flexibility,higher heat efficiency,and lower CO2 emission,and production of synthesis gas by coupling the decoking and pyrolysis processes.
