Abstract: IN CATALYST IN A REACTION TANK HAVING A MATERIAL FEED PIPE AT THE LOWER PORTION THEREOF AND A PRODUCT-TAKINGOUT-PIPE AT THE UPPER PORTION THEREOF, A DISCHARGE NOZZLE AND A SUCTION NOZZLE ARE PROVIDED, THE DISCHARGE NOZZLE BEING CONNECTED TO THE DISCHARGE SIDE OF A PUMP PROVIDED OUTSIDE THE REACTION TANK AND THE SUCTION NOZZLE BEING CONNECTED TO THE SUCTION SIDE OF THE PUMP, RESPECTIVELY. WHEN THE PUMP OPERATES, A REACTION LIQUID IS DISCHARGED FROM THE DISCHARGED NOZZLE AND THEN SUCKED INTO THE SUCTION NOZZLE ALONG WITH CATALYST. THUS, CATALYST IS RECOVERED IN A CATALYST RECOVERY TANK PROVIDED BETWEEN THE SUCTION NOZZLE AND THE PUMP, AND THE REACTION LIQUID IS CIRCULATED FROM THE PUMP TO THE SUCTION NOZZLE THROUGH THE DISCHARGE NOZZLE. EITHER THE DISCHARGE NOZZLE OR THE SUCTION NOZZLE

IS, AS OCCASION DEMANDS, SLID SO AS TO MAKE CONTACT WITH THE OTHER. THUS, THE INNER SURFACE OF THE SUCTION NOZZLE IS RINSED BY CIRCULATING A REACTION LIQUID, AND THEREBY CATALYST ADHERING TO THE INNER SURFACE OF THE SAID SUCTION NOZZLE IS REMOVED.

Abstract: Carbon nanotubes are produced by successively repositioning an axially extending rod-like carbonaceous anode (6) relative to a cathode surface (2a) such that a tip end surface of the anode (6a) successively faces on different portions of the cathode surface while impressing a direct current voltage therebetween, so that an arc discharge occurs with the simultaneous formation of carbonaceous deposits containing carbon nanotubes on each of the portions of the cathode surface. The carbonaceous deposits are scraped and collected. A device for carrying out the above method includes a driving member (5) for displacing the cathode surface relative to the anode.

Abstract: The components to be processed are introduced in a reactor packed with solid catalyst, through a pressure pipe located at the bottom of the reactor. Above the open end of this tube, a sucking tube removes continuously the processed substance together with exhausted catalyst particles which latter are adequately regenerated and backfed through the pressure pipe. The rate of feeding and outflow is regulated by varying the opened surfaces and distances from each other of the two pipes.

Abstract: PROBLEM TO BE SOLVED: To provide a method for recovering a superfine granular molybdenum sulfide catalyst contained in a liq. reaction product. SOLUTION: This method for recovering a superfine granular molybdenum sulfide catalyst contained in the distillation residue of a liq. reaction product includes (i) a combustion stage for burning the distillation residue at a temp. lower than the m.p. of the catalyst, (ii) a transfer stage for transferring the molybdenum oxide vapor formed in the combustion stage to its cooling and condensing stage and (iii) the cooling and condensing stage for cooling, condensing and solidifying the molybdenum oxide vapor transferred in the transfer stage.
