CATALYTIC REFORMING Process,Catalysts and Reactors

Feed quality Chemical composition
• Characterization of the feedstocks by:
• With a higher 0.85 N + A
– The same Octane content will be obtained at a lower severity
(temperature) and the product yield will be higher
– Or for the same severity (temperature), the Octane content will be
higher
– Higher naphtenic content. The T
endothermic reaction heat is
increased and the feed flow rate will be limited by the heater design
duty
• With lower 0.85 N + A
– Higher paraffin content. The hydrogen purity of the recycle gas
decreases and operation will be limited by the recycle compressor
capacity
• Impurities
0.85 N + A
– Temporary or permanent reduction of catalyst activity by poisons
contained in the feed
