I'm not sure how you prepare your catalysts. Do you calcine them? In my case, I don't calcine the catalysts. Then, before reaction testing, I pretreat the catalyst in the reactor. Even the catalyst is stored for one year, the activity is the same. |

Why "´ß»¯¼ÁÒѾ¸ßλ"? You can prepare it without calcination, store it, and then whenever you want to run a reaction, you then calcine or pretreat it at high temperature. If ´ß»¯¼ÁÒѾ¸ßλ, then you can re-pretreat it again before the reaction to remove contaminants from the catalyst surface. [ Last edited by zhenmafudan on 2008-6-6 at 21:13 ] |
