ABSTRACT:
A reactor comprises a vertically elongated cylindrical housing with at least one bottom in the housing which supports a catalyst bed which is permeable to gas and through which heat exchanger tubes extend. The construction includes a cylindrical wall within the housing which encloses the catalyst. The housing is constructed so that a cover thereof may be removed to lift the bottom together with the cylindrical wall and the catalyst bed with the tubes out of the housing. The cylindrical wall is advantageously formed by finned tubes. The construction advantageously includes upper and lower header portions and the heat exchanger tubes which extend through the bed are bent at each end and extend into these headers. In an alternate embodiment, the reactor has more than one bottom at spaced vertical locations. Coolant is advantageously supplied through one of the headers of the heat exchanger tubes, for example, a lower one for exit out through the upper one. In addition, gases are circulated for example, through the catalyst bed upwardly. In the case of multiple bottoms, the gas may be admitted intermediate the length of the reactor and circulated both upwardly and downwardly through the catalyts beds.
