What does cycle commissioning during the start-up of continuous reforming refer to? The startup process for oxidation-state catalysts in catalytic reforming is as follows: 1. Catalyst loading, 2. Catalyst circulation testing, 3. Catalyst drying, 4. Catalyst reduction, 5. Operation at full load. In my understanding, catalyst circulation testing involves moving the palladium catalyst back and forth between various reaction stages and regeneration processes. What’s not clear to me is whether moving the catalyst before it has been dried could cause significant wear to the catalyst (especially since moisture exacerbates this issue)
No, before operation begins, the lifting of the catalyst is also achieved through the use of gas, namely nitrogen, which is similar to normal operating conditions. There is basically no free water in the pipelines before startup, so the wear on the catalyst is very minimal. In fact, the wear on the catalyst during normal operation is somewhat greater than during the startup phase
