Zigzag bed

Recent research in China (Wang et al., 2007) has led to what is claimed to be a new HiGee - a rotating zigzag bed (RZB). The RZB is claimed to function without...

Politecnico di Milano and Ineos Vinyls UK developed a tubular fixed bed reactor comprising a metallic monolith 67,130). The walls were coated with catalytically achve material, and the monolith pieces were loaded lengthwise. Coming, the world leader in ceramic structured supports, developed metallic supports with straight channels, zigzag channels, and wall-flow channels. These metallic supports were produced by extrusion of metal powders, for example, copper, tin, zinc, aluminum, iron, silver, nickel, and mixtures and alloys (131). An alternative method is extmsion of softened bulk metal feed, for example, aluminum, copper, and alloys thereof. The metal surface can be covered with coating such as carbon, carbides, and alumina, for example, by application of a CVD technique (132).

The border between these zones is the front of total wetness (/v). which is not straight in most cases but a sharp zigzag line arises due to the inhomogeneity of external and internal pore diameters of the sorbent bed.
