Abstract (en)
[origin: US4695370A] A fluid bed catalytic apparatus and process for cracking a hydrocarbon charge and regenerating the catalyst where hot particles are contacted at the top of the cracking zone (1) with the sprayed liquid charge to be treated and thus produce (a) the vaporization of the charge in lines 10 and (b) an intimate charge-catalyst particles mixture. The catalyst particles are then withdrawn from the lower part of the cracking reactor (1), separated from the reaction effluent, stripped in reactor (17) and successively subjected to two regeneration steps, respectively in zones (22) and (37), zone (37) being a tubular reactor where the catalyst particles are driven upwardly by a carrying gas.
