PERIODIC AND NONPERIODIC DYNAMIC-RESPONSES FOR SORPTION DIFFUSION ANDREACTION IN A BERTY REACTOR

The dynamic effects of physisorption-diffusion of ethene and propene o ver alumina, silica gel, and zeolite adsorbents, and the additional ef fects of propene metathesis reaction over rhenium oxide catalyst on ga mma-alumina support, were characterized in a Berty reactor. Mathematic al models describing sorption-diffusion-reaction in propene metathesis were simplified and solved analytically by applying Laplace transform and Cauchy residue theorem. The experimental results obtained from bo th periodic and nonperiodic inputs to reactor inlet concentration were compared with model solutions. The models were used to study the sens itivity characteristics of the system parameters. The specific advanta ges and disadvantages of both periodic and nonperiodic inputs for the Berty reactor system are discussed.
