NTIS REPORT NO: DE82003369INW ABSTRACT: In October 1980, Air Products and Chemicals, Inc. began a three year contract with the DOE: Catalyst and Reactor Development for a Liquid Phase Fischer-Tropsch Process. The program contains four major tasks: (1) Project Work Plan, (2) Slurry Catalyst Development, (3) Slurry Reactor Design Studies, and (4) Pilot Facility Design. This report describes work carried out in the fourth quarter of the contract. In Task 2, the 300 mL and 1000 mL slurry reactors ordered for the contract were constructed and instrumented. Mass transfer tests in the No. 1 300 mL slurry reactor were incorporated into the baseline catalyst test, because of the low activity that was found in two tests of a ruthenium methanation catalyst in the slurry phase. Two modified conventional catalysts were prepared and five gas phase screening tests were carried out, giving additional information on the conditions required to produce an enhanced C sub 10+ fraction. Eight supported cluster catalysts were synthesized, and eleven were screened in the gas phase. In Task 3, measurements of gas holdup and solids dispersion were completed for the 1 to 5 mu m silica/isoparaffin system. Preliminary correlations were derived for gas holdup as a function of gas velocity and slurry density: a near zero-order dependence upon slurry velocity was observed. The column solids profile was constant for the conditions studied. Bubble diameters were measured photographically in the two-phase system.
