“…8 A number of literatures have reported that some parameters affected the catalytic performance of the naphtha reforming. 1,5,[9][10][11] However, the combined impact of the various variables with each other has not been reported. Investigating the reaction of catalytic naphtha reforming is very difficult owing to the many reactions borne out by the hundreds of hydrocarbons that are found in it.…”

Response surface methodology (RSM) is an expert method for demonstration of effective input factors and responses. In this study, RSM was used with the purpose of increasing the octane number of the primary feed (n‐heptane) in n‐heptane reforming reaction over Pt/Zr‐HMS catalysts. Based on the results of analysis of variance, the correlation coefficient values upper 0.9 were obtained for all responses. However, the results of n‐heptane conversion and selectivity to isomers as two responses were fit to Quadratic model and Research Octane Number was fit to Cubic model. Furthermore, the maximum n‐heptane conversion of 98.8 was obtained at T = 500°C, TOS = 3.5 h, and Si/Zr = 5. Also, at the optimal conditions of (T = 200°C, TOS = 3.5 h, and Si/Zr = 35) and (T = 500°C, TOS = 1 h, and Si/Zr = 20), the maximum isomers selectivity of 54.2 and RON of 100.0 was obtained, respectively.
