ABSTRACT:
A controlled method of transporting catalyst between two zones while inhibiting communication between the atmospheres of the zones is disclosed. Communication between the zones is inhibited by controlling pressure differences. The two zones are separated by a means to lift catalyst, which results in a savings in construction costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.
