摘要: PROBLEM TO BE SOLVED: To provide a method of equalizing heat distribution in a reactor tube housing a catalyst. SOLUTION: When a catalyst monolith is used, reaction heat can be dispersed as desired and consequently a heat gradient is lowered and efficiently and catalyst performance are improved. The method of equalizing the heat distribution on the catalyst of the tubular reactor is provided and this method comprises packing >=1 catalytic monolith into the respective tubes of the tubular reactor.

摘要: PROBLEM TO BE SOLVED: To enhance reaction efficiency by providing a draft tube equipped with a window or a slot in a reactor and circulating a process fluid through the window or the slot by the rotation of the impeller in the tube. SOLUTION: A reactor 10 suitable in use of reaction such as polymn., crystallization or the like for a polycondensation polymer has a draft tube having a slot 18 formed thereto built therein and an impeller 14 is arranged in the draft tube 16. The impeller 14 is rotated by external power through a shaft 12 and a process fluid is forcibly directed downwardly within the draft tube 16. At this time, a part of the process fluid is taken out of an outlet 24 as a product but the greater part thereof is repelled from the bottom part 10a of the reactor 10 to upwardly flow through an annular part 19 provided with a barrier plate 20 and heated/cooled by a heat exchange coil 28 to be returned into the draft tube 16 through the slot 18.
