ABSTRACT:
Catalyst, e.g., for a fluid catalytic cracker, is added automatically by a system consisting of an addition hopper which is periodically fed by gravity from a storage hopper, sealed off from the supply, and then pressurized with air to discharge its contents to the carrier gas line feeding the hydrocarbon conversion unit, e.g., the regenerator section of a Fluid Catalytic Cracking Unit. Sequencing can be by electronic timer-solenoid (or pneumatic) valve system.
