Abstract (en)
[origin: EP0323297A1] Process for the conversion of petroleum hydrocarbons in the presence of catalyst particles in a fluidised phase in a tubular reaction zone with essentially upward or downward flow, this process comprising at least one stage of steam cracking of at least one light hydrocarbon cut and a stage of catalytic cracking of at least one heavy hydrocarbon cut. The steam cracking is carried out by bringing into contact, in a fluidised bed of catalyst particles, the said light hydrocarbons and a quantity of steam equal to at least 20% by weight, the resulting temperature being between 650 and 850 DEG C. The catalytic cracking of the heavy hydrocarbons is carried out by injecting into the catalyst suspension effluents from the upstream part of the reaction zone, so that the temperature of the mixture is between 500 and 650 DEG C and is then returned to a temperature of between 475 and 550 DEG C.
