The shakedown of the portion of the BSU that was essential to the operation of the two-stage reactors was initiated in late December 1981 and has now been successfully completed as planned. A limited hydrodynamic study using the slurry bubble-column of the BSU has been conducted. The data included the system pressure-drop and the gas holdup at various gas velocities using Mobil base stock F-509. Limited data on gas holdup during normal synthesis operation was also obtained. This hydrodynamic data is part of the effort to improve our understanding of the hydrodynamics of a bubble-column reactor. The evaluation of the first slurry Fischer-Tropsch catalyst, a Fe/Cu/K/sub 2/CO/sub 3/ catalyst designated I-A, was initiated, and its first 350 hours of operation is reported. The run is being continued. The break-in operation of a second-stage ZSM-5 reactor, containing a ZSM-5 catalyst designated II-A, has also commenced without any problem. The operation was very smooth and highly successful considering the complexity of the pilot plant. During this operation, high gas holdup in the bubble-column reactor has been observed. This may limit the catalyst loading and the gas throughput of the reactor. Large amounts of heavy hydrocarbons retained in the slurry reactor have been observed also. This reactor-wax yield increased greatly with decreasing methane yield.
