  • Synthesis of ETBE as an octane number enhancer from ethanol and isobutene in a flow reactor under atmospheric pressure was studied. Amberlyst-15 and Amberlyst XN-1010 were used as catalysts within the temperature range of $70-140^{\circ}C$. The activity of Amberlyst 15 was higher than that of Amberlyst XN-1010. The reaction rate data obtained under differential reactor condition were tested by a linear regression method to determine the reaction mechanism and kinetic parameters. The ETBE synthesis reaction seems to be proceeded via the LHHW(Langmuir-Hinshelwood-Hougen-Watson) machanism. The activation energy of the surface reaction was estimated by the reaction rate constants as well as the adsorption equilibrium constants. Apparent activation energies are 18.64 and 24.19kcal/mol for Amberlyst-15 and Amberlyst XN-1010, respectively.
