Adsorption–desorption of reaction mixture components on ETBE synthesis over sulfonic resins

What is it about?

Effect of adsorption properties of commercial sulfonic acid resins of different morphology on the trend of temperature dependence of ethyl-tert-butyl ether (ETBE) yield in a reaction between ethanol and iso-butylene at elevated pressure studied. It has been shown that porous structure of a catalyst affects significantly the adsorption–desorption dynamics of reaction components. Consequently, at low temperatures the yield of ETBE is limited by adsorption–desorption dynamics, whereas at high temperatures it is restricted by thermodynamics. That results in the appearance of a maximum on the experimental dependence of the ETBE yield on temperature.
