Hydrocracking of Octacosane and Cobalt Fischer–Tropsch Wax over Nonsulfided NiMo and Pt-Based Catalysts
Autor: Wenping Ma, Jungshik Kang, Gary Jacobs, Shelley D. Hopps, Burtron H. Davis
Publikováno v: Reactions, Vol 2, Iss 4, Pp 374-390 (2021)
The effect of activation environment (N2, H2 and H2S/H2) on the hydrocracking performance of a NiMo/Al catalyst was studied at 380 °C and 3.5 MPa using octacosane (C28). The catalyst physical structure and acidity were characterized by BET, XRD, SEM

Autor: James C. Hower, John G. Groppo, Shelley D. Hopps, Tonya D. Morgan, Heileen Hsu-Kim, Ross K. Taggart
Publikováno v: Minerals; Volume 12; Issue 9; Pages: 1071
Four suites of fly ash, all generated at the same power plant, were selected for the study of the distribution of rare earth elements (REE). The fly ashes represented two runs of single-seam/single-mine coals and two runs of run-of-mine coals represe

Hydrogenation of carbon dioxide over iron carbide prepared from alkali metal promoted iron oxalate
Autor: Muthu Kumaran Gnanamani, Wilson D. Shafer, Hussein H. Hamdeh, Burtron H. Davis, Shelley D. Hopps
Publikováno v: Applied Catalysis A: General. 564:243-249
Iron carbide was prepared by the carburization of iron oxalate doped with various alkali metals in flowing CO at 400 °C. The addition of alkali metal (Li, Na, K, Rb or Cs) to iron oxalate was found to decrease the bulk iron carbides formation. Howev
