ABSTRACT:

In this Quarter three separate runs of the two-stage Fischer-Tropsch/ZSM-5 pilot plant were completed. A fourth, Run CT-256-12, was started at the end of the Quarter. Catalyst settling in the first-stage bubble-column reactor caused the ending of Runs 9 and 11, so the unit was modified before the latest run to help prevent this. Initial results from all three of these runs showed that Catalyst I-B gave low methane + ethane yields and high H sub 2 +CO conversions at moderate temperatures and pressures. Also, catalyst aging during Run CT-256-8 (Catalyst I-C) was analyzed using a mathematical model; a reactor-wax sample from Run CT-256-7 was analyzed using Field Ionization Mass Spectrometry; and hydrodynamic studies using the tall hot-flow bubble-columns were concluded. Investigated were real reactor waxes and the effect of solids and column diameter on gas holdup and bubble sizes.  Lastly, design base data were developed for the conceptual process design of a high liquid fuels Fischer-Tropsch commercial plant. 3 refs., 21 figs., 6 tabs.
