Abstract
Method and apparatus are provided for maintaining a substantially continuous gas flow through particulate solids in two zones. The solids are moved from a low pressure zone to a high pressure zone by means of a valveless lock hopper system. Maintenance of gas flow while simultaneously transferring particles between zones is accomplished without the use of moving equipment such as valves. The invention is particularly applicable in the regeneration of catalyst used in hydrocarbon conversion processes such as catalytic reforming.
