    • Fischer-Tropsch synthesis: Effect of ammonia in syngas on the Fischer-Tropsch synthesis performance of a precipitated iron catalyst 

      Ma, Wenping; Jacobs, Gary; Sparks, Dennis E.; Pendyala, Venkat Ramana Rao; Hopps, Shelley D.; Thomas, Gerald A.; Hamdeh, Hussein H.; MacLennan, Aimee; Hu, Yongfeng; Davis, Burtron H. (Elsevier B.V., 2015-06)
      The effect of ammonia in syngas on the Fischer-Tropsch synthesis (FTS) reaction over 100Fe/5.1Si/2.0Cu/3.0K catalyst was studied at 220-270 degrees C and 1.3 MPa using a 1-L slurry phase reactor. The ammonia added in syngas ...

    • Fischer-Tropsch synthesis: Effect of Cu, Mn and Zn addition on activity and product selectivity of cobalt ferrite 

      Gnanamani, Muthu Kumaran; Hamdeh, Hussein H.; Jacobs, Gary; Qian, Dali; Liu, Fang; Hopps, Shelley D.; Thomas, Gerald A.; Shafer, Wilson D.; Xiao, Qunfeng; Hu, Yongfeng; Davis, Burtron H. (Royal Society of Chemistry, 2016)
      The effect of Cu, Mn and Zn addition on cobalt ferrite was investigated for Fischer-Tropsch synthesis (FTS). Oxalate co-precipitation followed by decomposition under inert conditions was used to obtain various metal ...

    • Fischer-Tropsch synthesis: Effects of hydrohalic acids in syngas on a precipitated iron catalyst 

      Ma, Wenping; Jacobs, Gary; Thomas, Gerald A.; Shafer, Wilson D.; Sparks, Dennis E.; Hamdeh, Hussein H.; Davis, Burtron H. (American Chemical Society, 2015-05)
      The current investigation was undertaken to identify limits of hydrohalic acid (HX, X = F, Cl, Br) impurities in syngas and shed light on the mechanism of FIX poisoning of a 100 Fe/5.1 Si/2 Cu/3 K FTS catalyst under ...

    • Hydrogenation of Carbon Dioxide over Co-Fe Bimetallic Catalysts 

      Gnanamani, Muthu Kumaran; Jacobs, Gary; Hamdeh, Hussein H.; Shafer, Wilson D.; Liu, Fang; Hopps, Shelley D.; Thomas, Gerald A.; Davis, Burtron H. (American Chemical Society, 2016-02)
      A series of Co-Fe bimetallic catalysts was prepared, characterized, and studied for the hydrogenation of carbon dioxide. The catalyst precursors were prepared via an oxalate coprecipitation method. Monometallic (Co or Fe) ...

    • Hydrogenation of carbon dioxide over K-Promoted FeCo bimetallic catalysts prepared from mixed metal oxalates 

      Gnanamani, Muthu Kumaran; Hamdeh, Hussein H.; Jacobs, Gary; Shafer, Wilson D.; Hopps, Shelley D.; Thomas, Gerald A.; Davis, Burtron H. (John Wiley & Sons, Inc., 2017-04-07)
      The hydrogenation of carbon dioxide over K-promoted FeCo bimetallic catalysts prepared by sequential oxalate decomposition and carburization of FeCo with CO was studied in a fixed-bed reactor at 240 degrees C and 1.2MPa. ...
