Abstract
The reaction characteristics (conversion of reactant gas and yield of intermediate product) of simultaneous successive first-order reactions are analyzed by the two-phase model introduced in a previous paper for the case where these reactions take place in a packed fluidized-bed reactor under several operating conditions.
These reaction characteristics are influenced by the reaction rate constants of each reaction, the ratio of each reaction rate constant, fraction of catalyst in the bubble phase and the ratio of superficial gas velocity to minimum fluidized gas velocity.
The following results are obtained. When the reaction rate constants of each reaction decrease and when the fraction of catalyst in the bubble phase and the ratio of superficial gas velocity to minimum fluidized gas velocity increase under constant average residence time of reactant gas, conversion of reactant gas and yield of intermediate product increase and are almost the same as those for an ideal plug flow reactor.
