METHOD OF PROCESSING HYDROCARBON MATERIAL Russian patent published in 1997 - IPC

FIELD: petrochemistry, chemical engineering. SUBSTANCE: hydrocarbon material is brought in contact with fluidized catalyst bed with simultaneously feeding oxygen or oxygen-containing gas into reaction zone on one or more levels along catalyst bed height in amount providing oxygen to hydrocarbon molar ratio (0.01-0.1):1. Oxidative regeneration of coked catalyst is carried out in regeneration zone having direct heat contact with catalyst bed in reaction zone through surfaces separating these zones. Catalyst displacement from reaction zone into regeneration zone and regenerated catalyst displacement into reaction zone are performed with such a velocity as to provide an equilibrium level of the catalyst activity in reaction zone constituting 0.05-2.00 wt parts of catalyst per 1 wt part of raw material fed into reaction zone. Amount of oxygen or oxygen- containing mixture entered into regeneration zone ensures catalyst regeneration and its fluidization with maximum heat removal from regeneration zone. In reaction zone, hydrodynamic condition of fluidization is established favoring maximum heat removal from regeneration zone into reaction zone. Process is carried out at 450-560 C and the raw material volume velocity 0.5-5.0 0,5-5,0^-1. Employed catalyst contains crystalline metallosilicates with pentaxile structure. EFFECT: enhanced efficiency of process. 3 cl, 1 dwg, 1 tbl
