Abstract
Disclosed is a shell-and-tube reactor or heat exchanger, which alternately comprises a doughnut-type baffle plate and a first disc-type baffle plate in order to increase heat transfer efficiency. In the reactor or heat exchanger, a second disc-type baffle plate is placed in an empty space inside of the doughnut-type baffle plate, and some tubes, through the inside of which a first object for heat transfer with a heat transfer medium, are present in a region inside of the doughnut-type baffle plate and outside of the second disc-type baffle plate. Also disclosed is a method for producing an oxide, comprising: using said reactor or heat exchanger, and causing a catalytic vapor-phase oxidation reaction in the tubes, through the inside of which the first object for heat transfer with the heat transfer medium is passed.
