Packing element for heat and/or mass transfer, including a plurality of circumferentially spaced panel shaped wall members, each wall member extending radially outward from an inner end extending along a central axis of the packing element to an outer edge opposite to the inner end and at least part of the outer edge extending along a surface of revolution having the central axis as an axis of revolution.

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.

The invention relates to an improved catalyst based on a tableted molded catalyst body, containing a metal-containing mixture, containing copper, zinc, and aluminum, with calcium aluminate as a binder material with a weight fraction of calcium aluminate in the range of 1.0% to 30.0%, for synthesizing methanol from synthesis gas. The invention further relates to the production of the catalyst and to the use of the catalyst in the synthesis of methanol from synthesis gas.

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.
