<p><P>PROBLEM TO BE SOLVED: To provide a metal carrying apparatus of a continuous reaction regeneration type capable of simultaneously preparing several pseudo-equilibrated catalysts different in the carried metal amounts by a simple operation. <P>SOLUTION: An inner pipe 41 is inserted into an outer pipe 42 to construct a double pipe-type spray nozzle 40, which is fixed with screws to the lower end of a pedestal 50. The tip of the spray nozzle 40 is caused to penetrate through a seal ring 52 placed at the recess of the pedestal 50. A reaction pipe 20 is set on the pedestal 50. A heat-insulating block 55 is placed under the pedestal 50 to prevent the overheating of the spray nozzle 40. A metal-containing hydrocarbon oil supplied from the inner pipe 41 into the reaction pipe 20 is heated to a suitable temperature to be vaporized, is made into an atomized state by nitrogen gas and steam, and mixed with nitrogen for fluidization supplied through the outer pipe 42 for nitrogen gas introduction to introduce the fluid into the reaction pipe 20. Thus, the hydrocarbon oil in the reaction pipe is decomposed by the contact with the catalyst. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
