Abstract
A heat exchange catalytic process and reactor of the shell-and-tube type having a plurality of tubes extending longitudinally through the shell from a tube fluid inlet region to a tube fluid outlet region and baffles extending transversely across the shell dividing the shell between said inlet and outlet regions into at least three heat exchange zones through which each tube passes in sequence in heat exchange with that zone. A shell fluid is passed through the heat exchange zones in heat exchange with the tube fluid passing through the tubes. Transfer passages are provided connencting the heat exchange zones and are disposed so that the shell fluid passes through the second zone before or after it has passed through both the first and third zones. A particulate catalyst is disposed in either the shell heat exchange zones or, preferably, the tubes. The process utilises a heat exchange medium, particularly water, that does not change state under the prevailing conditions and is preferably fed to the shell heat exchange zones while the reactant stream passes through the catalyst disposed in the tubes. The process is particularly applicable to the selective hydrogenation of acetylenes…
