Deactivation of a coal liquefaction catalyst: Characterization by measurements of catalytic activity and catalyst physical properties

Autor: D.J. Sajkowski, Bruce C. Gates, F. Díez

Publikováno v: Scopus-Elsevier

Alumina-supported Co-Mo catalysts that had been used for liquefaction of Illinois No. 6 coal at 404°C, 171 atm, and weight hourly space velocity (WHSV) of 1.5 h −1 were characterized to provide measures of the deactivation. The intrinsic activitie

Pt clusters in BaKL zeolite : characterization by transmission electron microscopy, hydrogen chemisorption, and X-ray absorption spectroscopy

Autor: FS Modica, Bruce C. Gates, DC Diek Koningsberger, J Joop van Grondelle, Jeffrey T. Miller, M Vaarkamp, D.J. Sajkowski, GS Lane

Publikováno v: Catalysis Letters, 6(3-6), 369-381. Springer

Platinum supported on BaKL zeolite was characterized by Transmission Electron Microscopy (TEM), hydrogen chemisorption, and Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy. The results of all three techniques indicate the presence of hi
