Catalytic cracking of gas oil is accomplished over hot micro-spherical particles of silica alumina catalyst. The catalyst activity rapidly drops with the deposition of carbon, and spent catalyst continuously flows out of the bottom of the reactor.
There are many catalytic reforming processes available today for the octane upgrading and sulphur reduction of napthas. The production of aromatics is a feature of most. Platinum, moblybdenum, chromium oxides and other catalysts are employed in fixed, moving of fluidized beds.
The recycle of produced hydrogen at high pressures prevents olefin and diolefin formation and constitutes a highly effective form of chemical treating. All the process embody a heater followed by the catalyst chambers with the facilities for continuous or intermittent regeneration. The final product is isolated from a fractionation stage. Recycle hydrogen is scrubbed to remove hydrogen sulphide, from which sulphur or sulphric acid is manufactured by oxidation in a limited current of air.
