Temperature control in an ebullated bed reactor
A method has been discovered for controlling catalytic reactor bed temperature in an ebullated bed process. A sour, aromatic feedstock is mixed with a conventional ebullated bed residual oil feedstock in a controlled ratio. The aromatic feedstock is catalytically cracked and thereby releases heat. T...

| description | A method has been discovered for controlling catalytic reactor bed temperature in an ebullated bed process. A sour, aromatic feedstock is mixed with a conventional ebullated bed residual oil feedstock in a controlled ratio. The aromatic feedstock is catalytically cracked and thereby releases heat. The flow rate of the aromatic feedstock is controlled to maintain the reactor bed at a selected catalytic reaction temperature. Both feedstocks are upgraded to a fuel boiling range fraction and the fired heater is eliminated for the conventional feedstock and optionally for the hydrogen-containing gas feed stream as well. |
