Abstract: PURPOSE:To liquefy coal while catalytic activity at least equal to that of a powdery catalyst is dynamically revealed and maintained without the necessity for grinding, when a catalyst is synthesized or prepared, by performing coal liquefaction while vibrating a layer filled with a metal having catalytic activity. CONSTITUTION:A filled layer formed from a metal having catalytic activity, such as iron or molybdenum, in the form of a sphere or rod, is maintained at 350-450 deg.C under a hydrogen pressure of 10-20 MPa, the filling material therein is vibrated, and hydrogen, sulfur, a solvent, and coal are supplied to the vibrated layer, thus performing coal liquefaction. It is desirable that the size of the filling material is in the range from 1 to 5 mm. To vibrate the filling material, the container as a whole can be vibrated, or only the filling material can be vibrated by utilizing electromagnetic induction. It is desirable that the frequency of vibration is at least 20 Hz.

Abstract: PROBLEM TO BE SOLVED: To obtain an aerogel of an excellent bulk body free from the generation of shrinkage and crack by holding a wet gel body of a metal oxide, a solvent and a specific material under a prescribed condition and removing the solvent to dry the wet gel body. SOLUTION: The wet gel body of the metal oxide (e.g. a silica wet gel body obtained by impregnating the gel body, which is obtained by mixing tetramethoxysilane with a methanol/ammonia water, pouring to a prescribed shaped vessel and allowing to stand, with methanol to remove an unreacted component), the solvent (e.g. methanol) and a granular zeolite having preferably 2-3mm average particle diameter are held under the critical condition or super critical condition (e.g. 280 deg.C 140atm) of the solvent preferably for 1-3hr and after that, the solvent is gradually released and removed to dry the wet gel body.

Abstract: PROBLEM TO BE SOLVED: To provide a carbon whisker having a diameter of μm order and easily handleable as an industrial product and provide its production process. SOLUTION: The carbon whisker has a diameter of 0.1-10μm.
