What does shutdown for reforming and regeneration heat mean? ?
Stop feeding hot air; keep nitrogen circulation running and the heater running.
The catalyst circulation is stopped, the burning air flow continues, and the nitrogen valve is open
The catalyst stops cycling and charring; the nitrogen valve at the lower part of the regenerator opens, chlorine injection for regeneration ceases, while the electric heater remains active.
