For comparison, Co/SiO2 and Co-supported montmorillonite treated with dilute HNO3 (acid-clay) were also prepared. The materials were characterized by XRD, H2-TPR, NH3-TPD, O2 titration, and N2 adsorption−desorption. The Co-supported catalysts were comparatively investigated for Fischer−Tropsch (FT) synthesis in a fixed-bed reactor under the conditions of 1 MPa, 508 K, H2/CO = 2, and W/F = 5.02 g·h·mol−1. The results indicate that the activities of the catalysts (i.e., CO conversions) increase in the order of Co/Na-Clay Co/Si-PILC ≈ Co/acid-clay ≈ Co/Al-PILC ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie101163w [article] Co / pillared clay bifunctional catalyst for controlling the product distribution of fischer − tropsch synthesis [texte imprimé] / Qing-Qing Hao, Auteur ; Guang-Wei Wang, Auteur ; Zhao-Tie Liu, Auteur . - 2010 . - pp. 9004–9011.
