优化现在越来越难投了，我做了一大堆优化，放弃了

Industrial & Engineering  Chemistry Research Of ACS may be suitable for your artlcle.

catalysis today怎么样？

I thnik you should analysis your article again even in detail. If just like you said. In my view, there are serveral choice: 1. Industrial & Engineering  Chemistry Research This journal focus on industrial application. 2. New Journal of Chemistry. This journal relatively gerneral overview. 3. CHEMSUSCHEM or ChemCatChem: These two are new journals. They are more easier to accept your articles，

ACB可以试一下！

catalysis today or fuel 应该是可以的

Catal. Lett.差不多 或者IEC均可，个人比较趋向于IEC ，LETT现在对文章长短也没那么严格的限制了，也有很多比较长的文章

IEC is the best choise of course.
