In the new Talara Refinery, a naphtha Catalytic Reform unit will be operated, to obtain high octane gasoline (100 octane), the hydrotreated naphtha is passed through three reactors in series that contain Pt / Re catalysts on alumina-support. In the course of the normal cycle of operation, the natural deactivation of the catalyst by coke deposition occurs due to the adverse reactions favored by the increase in severity necessary to obtain a reforming in specification. At the end of the normal operating cycle (approximately 1 year), the catalyst must be regenerated to recover both metallic and acid activity and start again with a new operating cycle. Regeneration of the catalyst must be carried out with care, trying to avoid adverse problems of agglomeration or sintering of the catalyst. First, the coke burning will be carried out at two levels of temperatures until obtaining a maximum% of coke in the catalyst of 0.1% by weight, followed by the recovery of the catalyst activity, where in the presence of chlorine and oxygen the activity of the acid phase of the catalyst. In the burning stage, combustion was carried out at bed temperatures of 400 and 480 ° C with O2 content of 0.5 to 1% by volume. The temperature in the beds should not exceed 510 ° C during burning, combustion should be controlled by regulating the air intake to avoid sintering problems (> 500 ° C in the presence of humidity). In the activity recovery stage, a temperature of 520 °C is maintained, but the O2 concentration increases by 5% and 12% in the oxychlorination and calcination stages. Here activation of the active phase of the catalyst and the dispersion of the platinum crystallites is achieved.
