HIGH EFFICIENCY REGENERATOR APPARATUS

摘要

Disclosed is a high efficiency catalyst regenerator employing a barrier separating upper and lower regenerator sections which minimizes structural damage caused by thermal stress in portions of the barrier subject to different degrees of heating. In one embodiment a hot internal cone portion of the regenerator forming the barrier is spaced from a cooler regenerator vessel sidewall. The space may be an unfilled void space or it may be filled with an insulation material. In another embodiment the regenerator vessel is physically separated into upper and lower sections with the barrier being formed by an upper section containing a concave dish head at its bottom and the lower section containing a convex dish head at its top which are connected by an extension of a riser interconnecting the concave and convex dishes.
