Abstract
This invention pertains to a continuous catalytic process, for example, for the metathesis of olefins that uses a catalyst circulating in a moving bed in at least one reaction zone operating in the liquid phase and in a regenerator, with a lift to transfer the deactivated catalyst emerging from the reaction zone to the regenerator, whereby said process is characterized by the fact that the transfer is accomplished by a gas that does not react with the catalyst and with the stripping off of at least a portion of the organic matter that is adsorbed on the deactivated catalyst.
