The effect of run time, temperature, conversion and inlet steam‐to‐naphtha ratio on the rate of coke deposition during naphtha pyrolysis in an annular tubular reactor has been investigated. Rates of coke deposition increased with increasing temperature, conversion and inlet naphtha partial pressure. Pyrolysis and coking models available for naphtha cracking were used to calculate the total coke deposited by treating the temperature difference between the reacting fluid and the outer reactor wall as a parameter. For all the runs, the experimental and calculated coking rates were in close agreement for an assumed temperature difference of 35‐45°C.
