✦ Synopsis

This study concerns experimental investigations of the forced unsteady-state operation of trickle-bed reactors. The hydrogenation of cyclohexene to cyclohexane and cl-methylstyrene to cumene on palladium catalysts were taken as model exothermic reactions. Changes in the control variables (e.g. feed composition, feed rate, temperature) strongly influence the regime and performance of a trickle-bed reactor. The aim of the present study of cyclohexene hydrogenation was to seek conditions of periodic operation that would enable higher average inlet concentrations to be used without evaporating the feed mixture. For a-methylstyrene hydrogenation, the aim was to discover periodic operating conditions that would improve the time-average conversion relative to that under steady-state operation. INTRODIJmION

Current technology in the area of a regenerative processes for the removal of SO, from stack gases is too expensive. As an alternative, during the 1970's, work was done on the effectiveness of activated carbon operating in a trickle bed reactor to remove SO, by oxidizing it to form sulfuric acid. Re
