Sunshine Program for fiscal 1981. Research on direct coal-liquefaction reactor; 1981 nendo sekitan chokusetsu ekika hannoki no kenkyu seika hokokusho

Abstract

The research aims to develop a new-type high-efficiency reactor for direct coal-liquefaction from a reaction engineering viewpoint and, at the same time, to settle problems expected to occur in industrializing this technique. The research items are Item 1 on the analysis of characteristics of a tubular continuous reactor and Item 2 on high-activity catalysts. Under Item 1, on the assumption that liquefaction reaction is dominantly a reaction in a continuous phase, a reactor is selected in consideration of homogeneous-phase reaction, and operating conditions are set according to the selected reactor and to the liquefaction reaction characteristics. A somewhat large Re number is assigned to the paste. Since the hydrogen partial pressure lowers with the progress of reaction, hydrogen is resupplied at the middle of the reaction tube. The volume of gas increases toward the final stage of reaction, decreasing the continuous phase holdup. Since it is undesirable to let the decrease stand, a vapor-liquid separator is provided for the control of the gas volume. In this fiscal year, investigation is conducted into details so as to determine if the reactor is equipped with intended characteristics. Under Item 2, the iron ore is deemed to be the most promising as disposal  More>>
