Fixed-bed multi-tubular reactor for the manufacture of vinyl acetate |
| abstract |
Provided is a method for producing vinyl acetate-based products by gas-phase contact oxidation reaction of lower olefins, acetic acid and oxygen using a fixed-bed multi-tubular reactor, which can accurately measure the content of the inside of the reaction tube even if the process is operated for a long period of time. Catalyst layer temperature reaction device. A fixed-bed multi-tubular reactor for producing vinyl acetate-based substances according to an embodiment includes a plurality of reaction tubes, a thermometer protection tube inserted into at least one of the plurality of reaction tubes, and a thermometer protection tube inserted into the thermometer protection tube. The thermometer and the shielding material arranged above the reaction tube into which the thermometer protective tube is inserted and assembled to the thermometer protective tube, the effective projection area of the shielding material completely covers the inlet opening of the reaction tube into which the thermometer protective tube is inserted. |
