Influence of process variables and optimization of RON in catalytic naphtha reforming using RSM approach

Optimization of RON via reforming of n-octane as a model compound over bimetallic Pt-Re/Al ₂O ₃ catalyst under different operating conditions was studied. The relationship between RON, with three reaction variables namely temperature (480 -510°C), pressure (10-30 bar) and space velocity LHSV (1.2-1.8 h ^-1) were presented as empirical mathematical model by applying RSM. The equation model was tested with analysis of variance with 95% degree confidence. Numerical analysis concluded that the equation models fitted well with the experimental results for naphtha reforming process. The study revealed that RON was 105 at optimum reaction temperature of 515°C, operating pressure of 17 bar and LHSV of 1.0 h ^-1-'.
