Report of liquefaction catalyst study meeting (March 1996); Ekika shokubai kentokai hokoku

Abstract

Studied in the research are four iron-based catalysts, which are natural pyrite, synthetic iron sulfide, synthetic iron hydroxide, and catalyst-attached carbon. Tanito Harum coal is treated in a 0.01t/d-capable continuous operation furnace (once-through) under conditions of 450 degrees C and 170kgf/cm{sup 2} with catalyst addition of 1.0, 3.0wt% (catalyst-attached carbon 0.6, 1.0wt%), and a liquid yield of 41.5-48.6wt%-daf coal is achieved. A higher yield results when more catalyst is added. The same yield as achieved by the addition of 3wt% natural pyrite is obtained by the addition of 1.9wt% synthetic iron sulfide, 1.5wt% of synthetic iron hydroxide, or 0.7wt% catalyst-attached coal. The catalyst cost for treating a ton of coal is 4-9 hundred yen, which is far more expensive than the cost set forth as the target. Catalysts whose production process embodiment is now under study are natural pyrite and synthetic iron sulfide, and studies for others are just preliminary. Provided that the practical application of the liquefaction technology realizes in about 2000, then the petroleum price is predicted to be 23 dollars per barrel. Coal liquefaction products will have to be produced at a cost which will enable competition with the said petroleum price. (NEDO)
