ABSTRACT:
This invention relates to a method for on-line decoking of flame-cracking reactors whereby decoking is achieved without interruption of the normal operation of such reactors and without the necessity to change feed equipment and/or disassemble reactor components. While maintaining the temperature of the effluent at 1000.degree. C. to 2000.degree. C., the flow of the hydrocarbon feedstock in the reactor is periodically stopped for a time sufficient to reduce the carbon deposits to an acceptable level.
