Abstract:
     The hot catalyst particles are contacted with the liq. raw material sprayed from top section of the cracking zone, so the raw material is vaporized in a pipe and intimately mixed with catalyst particles. Then the catalyst is discharged from the bottom of the cracking reactor, separated from the effluent, having been stripped in the reactor. The spent catalyst is regenerated in two stages, the second stage regenerator is a tubular reactor, in which the catalyst particles are carried up by carrier gas.
