초록/요약
Coking has presented dificulties in reactions including pyrolysis and steam has been added to reducecoking. In this study, the effect of steam on coking in the pyrolysis of naphtha components was studied thermody-namically and experimentally for non-catalytic tubular reactor systems. The qualitative relations betwen these twothermodynamic and experimental studies were established. In both studies coking was reduced as the steam ratioincreased. However, experimental studies indicated that the reduction was more effective for smaller values of the ratio,leading to an effective ratio of about 0.5, and that weak coking still ocurred for the ratio greater than the thermody-namic zero-coke ratio.
