Abstract:
A fluid state catalytic cracking reactor comprising an essentially tubular, vertical chamber in which a charge to be cracked is placed in contact with a flow of catalyst particles that move following a flow that is essentially upward,said vertical chamber comprising in its lower portion a catalyst supply area for supplying catalyst particles that are at least partially regenerated, an injection area for injecting the charge to be cracked, at least one solid fastened static mixer packing element, located between the catalyst supply area and the injection area of the charge to be cracked, that extends over all or part of the cross section of the reactor and comprises a network of cells through which pass the catalyst particles, wherein said network ensures at least one division and recombination of the flow of catalyst particles, so as to redistribute the particles in a homogenous manner over the cross section of the reactor, and wherein said network of cells deviates in a radial manner the direction of the flow of gas and particles that passes through it by directing about 50% of the flow of gas and particles in a first direction and directing about 50% of the flow of gas and particles in a second direction, wherein the second direction has an angle of 10 to 90 degrees from the first direction, and an elevator gas injection area located upstream of the catalyst supply area, for introducing an elevator gas.
