摘要： 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.

摘要： A classifying fluid bed granulation unit includes a perforated bed floor; a fluid bed section; a solid feed inlet or internal crushing device; a fluidization air inlet; a liquid solution or melt feed inlet and nozzles; an air outlet; and a product outlet; wherein the fluid bed section comprises at least one particle classification element comprising one or more vertically inclined channels having top and bottom end feed openings, and wherein the one or more vertically inclined channels have upper and lower side slots. In operation of the above fluid bed granulation unit, each channel of the element is separating particles into large particle and small particle fractions and transporting the large particle fraction upwards and the small particle fraction downwards in each channel, and the large particle and small particle fractions are transported out of the upper and lower side slots, respectively.

摘要： Surface-active solid-phase catalyst activity may be substantially improved by creating deliberate repetitive surface-to-surface contact between portions of the active surfaces of catalyst objects. While they are immersed in reactant material such contact between portions of the active surfaces of catalyst objects can substantially activate the surfaces of many heterogeneous catalysts. Examples are given of such action employing a multitude of predetermined shapes, supported catalyst structures, etc. agitated or otherwise brought into contact to produce numerous surface collisions. One embodiment employs a gear pump mechanism with catalytically active-surfaced gear teeth to create the repetitive transient contacting action during pumping of a flow of reactant. The invention is applicable to many other forms for creating transient catalytic surface contacting action. Optionally catalytic output of such systems may be significantly further improved by employing radiant energy or vibration.
