چکیده | ||
A response surface methodology (RSM) with 3 levels and 4 variables was used to model and optimize the n-heptane isomerization kinetic process over Pt-HZSM-5/HMS catalysts in a fixed bed micro reactor. 30 sets of isomerization rate tests were performed at different conditions of H2 flow rate (20-45 ccmin−1), n-heptane flow rate (2-4.5 cch−1), the temperatures (200-350 °C), and the weight percent of HZSM-5 (10-40%). It was observed that the amounts of HZSM-5 into Pt-HMS structure has the greatest effect on the rate of reaction. The surface and contour plots confirm that the rates do not considerably change versus temperature, n-heptane and H2 flow rates. 0.24 molg−1s−1 is the highest reaction rate obtained in the 4.5 cch−1 n-heptane and 45 cc min−1 H2 flow rate. The RSM was effective for predicting and optimizing this process. The modelling results also show both power-law and Langmuir–Hinshelwood models are in agreement with the experimental data. | ||
