Catalytic reforming; process variables; physical and chemical properties of catalyst

The effect of process variables and physical and chemical properties of catalysts on the rates of reactions in catalytic reforming was studied. The experiments were carried out on apilot plant scale under the following process canditions:temperature range 490-525 C, Weight Hourly Space Velocity (WHSV)range 2.7-5.4 1/h, H/CH ratio 7 and 5-6, operating pressure 27and 12 bar. High pressure catalyst R-16G and low pressure catalyst R-62were studied. It was found that temperature increase favourably effects theRON increase and improves the gasoline quality, regardless of thecatalyst type. The experiments indicated that R-62 is more active than R-16Gin promoting aromatization reactions, because it enablesoperating at lower pressure. This statement is correlated withthe knowledge of "structure insensitivity" of naphthenesdehydrogenation reactions. Physical properties of spent catalysty and coke deposit onthem showed that there was no deactivation of the catalystsbecause the catalysts exposure time in the reactor was too short(approx. 23 hours).
