Abstract
PURPOSE: To raise the economy of coal liquefaction by effectively utilizing resources by using the system in which coal is mixed with a solvent and then subjected to a hydrogenation treatment at high temperature and high pressure using as a catalyst blast furnace slag, converter slag, or rolling sludge.
CONSTITUTION: Coal is mixed with a solvent and a catalyst, e.g., blast furnace slag, converter slag, rolling sludge, or a mixture of these, and then subjected to a hydrogenation at high temperature and high pressure. The preferred amount of the catalyst to add is approx. 1W10wt% on the basis of the amount of coal, although differ with ash content of coal and treatment condition. Because the addition of 10wt% or more gives no catalytic effect. Also, in order to increase the catalytic effect of these slags, it is desirable to pulverize the slags to a grain size of 0.1mm or less.
