“…From these observations, it can be concluded that a lower ramp rate is much more preferred for regeneration studies and it is in agreement with most industrial application as noted by Ren et al [13] that stated that the low temperature are usually employed to improve control the coke combustion. The temperature effect on the spent catalyst under nitrogen gas in Figure 2 of 400°C, 500°C, 600°C also produces absorption bands range 2100-2270 cm -1 showing small but exposed presence of CC triple bond distribution (corresponding to CC triple bond stretching) presence of combustion which is as a result of hydrocracking not needed in reforming process leading to coke formation.…”

“…The absorption bands at 2359.02, 2354.20 and 2261.61 cm -1 has no significant effective functional group because they have weak intensity while absorption band at 1644.37 and 1641.48 cm -1 corresponded C=C stretching of C=C in alkenes and are possible due to the adsorption of olefin and aromatics on the catalyst metal surface [13]. This may indicate that the coke species found near the active metal are soft coke and it is mainly made up of unsaturated hydrocarbon and heavy aromatics.…”

Catalytic reforming process will continue play an important role in meeting the world's demands for high octane gasoline, petrochemicals and hydrogen hence the need to embark on continued improvement of the process. This work examined the effect of temperature on the regeneration of Pt/Al 2 O 3 catalyst employed in semi regenerative fixed bed process. Samples of the catalyst were obtained from a running process (on line) at targeted periods of 10000 and 14000 hours of operation when the catalyst would have been deactivated to a degree. The catalyst samples which have undergone deactivation were regenerated at varying temperature conditions. The range of temperature studied is 400-800°C. The deactivated, regenerated and fresh catalyst samples were analyzed using FTIR, XRD and XRF to establish the extent of deactivation and regeneration. The progress of the regeneration was also monitored with gravimetric measurement of the weight losses. The work established an optimum regeneration temperature of 500°C. The optimum temperature can be employed as is a firm basis for regeneration process control and optimization.
