Abstract
Gasification technology of solid fuels in molten carbonates has been selected as one of the advanced gasification systems. The molten carbonates employed in this study are eutectic salts of Na_2CO_3 (43mol%) and K_2CO_3 (57mol%). As the advantages of utilization of the eutectic salts for coal gasification, the alkali metals play a role for the gasification catalyst, desulfurization solvent and capture material of ash particles. The gasification test results show that the main compositions in the product gas are CO and H_2. H_2S and COS concentrations in the product gas is low enough to introduce the gasified gas into an Molten Carbonate Fuel Cell (MCFC) system, in which H_2S and COS concentrations should be less than 1ppm in the gasified gas.
