150 T/D Coal liquefaction pilot plant (PP) supported by New Energyand Industrial Technology Development Organization (NEDO) was successfully operatedwithout any serious trouble throughout five runs operated till 1998.
The most important object in this project is to develop Demonstration Plant orCommercial Plant, or to take a varieties of engineering data including performance testof each equipment.
Additionally, it is very important to establish commercial acceptability of coal liquefactionproducts by means of clearing their chemical component and toxicological properties.
The works reported here are those which relate to characteristic properties of coalliquefaction products and their toxicological properties. Also we are going to mentionour planning concerning the toxicological assessment to be done.
