ABSTRACT OF THE DISCLOSURE The invention relates to an integrated, two stage coking and steam cracking process for the production of un- saturated light hydrocarbons. A heavy hydrocarbonaceous oil is first coked in a fluid coking zone. High temperature cracking in the presence of steam is carried out on the vaporous coker conversion product by injecting into the vapors a stream of hot coke particles at a sufficient temperature and in sufficient amount to raise the coker vapors to steam cracking temperature and supply the endo- thermic heat of reaction. The solids are separated from the gas and sent to the fluid coking zone and the gas is quenched to stop olefin degradation reactions.
