A method for facilitating the distribution of the flow of one or more streams within a bed vessel is provided. Disposed within the bed vessel are internal materials and structures including multiple operating zones. One type of operating zone can be a processing zone composed of one or more beds of solid processing material. Another type of operating zone can be a treating zone. Treating zones can facilitate the distribution of the one or more streams fed to processing zones. The distribution can facilitate contact between the feed streams and the processing materials contained in the processing zones.

A cooling tower (2) for cooling a liquid (4) with a gas (6), which cooling tower (2) comprises: (i) a vessel (8) for receiving the gas (6) passing upwardly and the liquid (4) passing downwardly, with the liquid (4) being hotter than the gas (6); (ii) a gas outlet (4) which is at a top portion (16) of the vessel (8) and which is for allowing the gas (6) to pass out of the vessel (8), (iii) a support member (20) which is positioned across a bottom portion (22) of the vessel (8): (iv) a plurality of apertures (24) which are in the support member (20) and through which the gas (6) and the liquid (4) are able to pass; (v) a fluidised bed (26) of packing elements (28) on the support member (20); (vi) liquid emitting means (30) which is positioned in the vessel (8) above the fluidised bed (26), and which is for emitting alas liquid (4) to be cooled such the liquid (4) passes downwardly towards the fluidised bed (26); (vii) pump means (32) for pumping the liquid to the liquid emitting means (30); and (viii) a fan (34) for blowing the pas upwardly through the fluidised bed (26), and the cooling tower (2) being such that it includes (ix) control means (31) for controlling (a) the velocity of the gas through die vessel (8), and (b) the liquid to gas ratio in the vessel (8), whereby the fluidised bed (26) is caused to operate at a tumbling rate which when combined with selected pre-fluidised packing height causes an approach temperature of below 10 F. (5.6 C.); (x) wherein the tumbling rate is controlled by a combination of controlled gas velocity and liquid to gas ratio creating turbulent mixing and tumbling of packing elements (28) in the fluidised bed (26); (xi) and wherein the pre-fluidised height of the fluidised bed (26) is from 0.15-1.0 m.

A catalyst carrier may have a cross-sectional shape that may include a plurality of surface channels having a first channel width and a second channel width, where the first channel width may be closer to a periphery of the cross-sectional shape than the second channel width and the first channel width may be less than the second channel width. The cross-sectional shape may further include a plurality of surface features where at least one surface feature is located between at least one pair of surface channels. The cross-sectional shape may further include a ratio L.sub.OC/L.sub.SCP of at least about 1.7, where L.sub.OC is a length of a total contour of the cross-sectional shape and L.sub.SCP is a length of an outer simple convex perimeter of the cross-sectional shape.

In a method of manufacturing objects, extrudable ceramic forming material is extruded through multiple dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extrusion to vary the position of several extrudate streams exiting the dies. Extruded objects are defined by spokes corresponding to the extrudate streams with the streams having a varying spacing from a central axis.
