Abstract
A process and apparatus for contacting a fluid with the walls of a vessel are characterized by flow of the fluid alternatingly (a) through a structure within the vessel and having passages angled to the general direction of flow in the vessel and (b) through a space between the structure and the vessel walls. The structure can be for example a cross flow ceramic or metal honeycomb or a stack of profiled plates or of apertured plates such as expanded metal. The structure can carry a catalytic coating and then affords high activity and low pressure drop. The process and apparatus are especially suitable for endothermic tubular steam hydrocarbon reforming.
