The catalyst production system has been developed for a 150t/d NEDOL process pilot plant (PP). The following results were obtained through the PP operation;
(1) Catalytic activity of pulverized pyrite in an inert atmosphere of 0.7μm of median diameter compares favorably with that of the synthetic pyrite.
(2) From a viewpoint of economical and operable efficiency, two stage pyrite pulverization system (wet-type ball mill-wet-type agitated mill) is the optimum catalyst production system.
(3) Catalyst slurry of pulverized pyrite characterizes high viscous and pseudo-plastic.
(4) It was confirmed through the PP operation that the catalyst production system designed from above test data operated stably and produced highly active catalyst.
