Improvements in the Beckmann rearrangement process by using highly selective mesoporous catalysts
(Elsevier, 2016-01)
The Beckmann rearrangement of cyclohexanone oxime (CHO) into e-Caprolactam (e-C) at 300e380 C and W/F ¼ 1e60 gh/mol over a Al-MCM-41 catalyst was studied in a flow reactor at atmospheric pressure. Different reaction ...
Heterogeneous hydrogenation of nitroaromatic compounds on gold catalysts: Influence of titanium substitution in MCM-41 mesoporous supports
(Elsevier Science, 2016-02)
A series of Ti-modified MCM-41 supports and their respective Au catalysts were prepared and characterized to study the effect of titanium into the support and on the characteristics of the Au surface species for heterogeneous ...
