Catalytic activity of synthetic saponite clays: effects of tetrahedral and octahedral composition
Vogels, R.J.M.J., Kloprogge, J. Theo, & Geus, John W. (2005) Catalytic activity of synthetic saponite clays: effects of tetrahedral and octahedral composition. Journal of Catalysis, 231(2), pp. 443-452.
This paper describes the catalytic characteristics of synthetic saponites with well-known chemical composition, thermal stability and acidity in three catalytic reactions: 1) catalytic cracking of n-dodecane, 2) hydro-isomerization of n-heptane and 3) Friedel-Crafts alkylation of benzene. Saponites with Mg in the octahedral position was by far the best catalyst for the catalytic cracking of n-dodecane, which can be explained by the higher surface area of these saponites compared to saponites with other compositions. All saponites performed better in the hydro-isomerization reaction of n-heptane and Friedel-Crafts alkylation compared to commercially available catalysts such as HZSM-5 and ASA. The shape selectivity in the Friedel-Crafts alkylation of benzene towards p- and o-DIOPB was remarkably high for the synthetic saponites

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
