| Normally, the calciniation is to reduce Nitrogen group around 450 degree. This is beacuse the N is toxic to the active center of your catalysts. Sometimes, it also can promote the reaction or no influence. This depends on your reaction. For example, the oxidation of alchol to aldehyde or acid. There is no big influence. |
