<P>PROBLEM TO BE SOLVED: To eliminate a useless space inside a reactor and to separate and discharge liquid and a catalyst remaining after completion of reaction. <P>SOLUTION: A raw material gas 28 is supplied from a delivery port of a gas distributor 30 into the reactor 21 of a generally cylindrical shape. A reacting liquid 24, the raw material gas and the catalyst 25 are made to flow vertically and react with each other inside the reactor. A catalyst separation apparatus 22 is provided with a partition plate 35 having an opening of a cylindrical wall 36 in the center on the lower side of the gas distributor 30. A riser tube 39 is inserted to the inside of the cylindrical wall 36 and an ascending flow is generated by the gas. A small hole 43 is arranged on the outer periphery side of the partition plate 35, and a down tube 44 is inserted therethrough and is placed alonside a recessed curved surface of the lower end part of the reactor. The upper end of the down tube 44 is protruded upward of the partition plate and is surrounded by a roof section 45. Catalyst separation filters 47 and discharge pipes 48 are arranged below the partition plate. The partition plate, the down tube and the riser tube form a circulation passage for slurry, the slurry discharged from a lower end outlet of the down tube is raised in a stagnation space, and product liquid is separated by the catalyst separation filters. <P>COPYRIGHT: (C)2013,JPO&INPIT |
