Description
Summary:A rapid response technique for measuring the amount of reactant and product adsorbed on a catalyst at reaction conditions was developed. The technique was evaluated using the dehydration reaction of t-butyl alcohol over alumina at 195 °C and 1 atm pressure. Pure component isotherms were determined for t-butyl alcohol, water and isobutylene at 195 °C and pressures up to 600 mm Hg as well as binary isotherms for alcohol-water mixtures. Based on the adsorption data, a relatively simple kinetic reaction rate equation was proposed and evaluated. The rate equation gave an excellent correlation of integral conversion data obtained from fixedbed reactor studies.
