Abstract
This invention is a reforming process that employs at least two moving bed reaction zones. One of the reaction zones, called the lead reaction zone, passes catalyst particles and a hydrocarbon-containing effluent to the other reaction zone, which operates at an inlet temperature that is at least 60.degree. F. (33.degree. C.) hotter than the lead reaction zone. In a preferred embodiment, this invention employs no heating between the combined feed exchanger and the lead reaction zone. This invention is particularly applicable to reforming processes that employ continuous regeneration sections.
