Pulsation reactor technology is a thermal procedure for manufacturing fine powders with precisely defined properties. Pulsation reactor technology is a thermal procedure with a special functional principle that results in reaction parameters and a reaction medium, and which ultimately leads to other property parameters in terms of surface, reactivity, homogeneity and particle size of the powder material. The technology has proven particularly effective in the manufacture of ceramic and submicroscale powders, as well as in the production of highly active catalysts. Also, simple oxides such as zirconium oxide with doping elements or mixed oxides like spinel can be produced in the pulsation reactor. == History == A British scientist called B. Higgins discovered the phenomenon of the pulsating flame in 1777. The phenomenon was described in specialist literature as the “singing flame”. However, no suitable application was found until 1930. Paul Schmidt was the first to employ the pulsating flame with the invention of the ARGUS-Schmidt pipe (Figure 1). Pulsating combustion was also used to generate hot gas for heating purposes and to fire boilers. The principle was tested in the eighties at the SKET Institute in Weimar to determine the suitability of pulsating combustion as a unit for performing thermal, material-modifying processes. The unit was already being referred to as a pulsation reactor by the Institute at that time. As well as the process of cement clinker firing, the manufacture of polishing agents from iron oxalate for the optical industry and the manufacture of surface-active catalyst substrates from gibbsite were also investigated. Pulsation reactor technology came to the fore from the nineties through its use in environmental technology, particularly in sludge drying and the regeneration of resin-bonded foundry sands. From 2000 the pulsation reactor was used to produce catalytic powders on an industrial scale. The principle of pulsating combustion was developed over the years by the company IBU-tec advanced materials AG (which emerged from the SKET Institute and still exists today), which finally tested and commissioned another test facility in 2008. Thanks to the continuous optimisation of the reactors, it was now possible to use an oxidising, inert or reducing hot gas atmosphere to treat materials as required. It also emerged that the improved plant was particularly suitable for manufacturing fine particles and catalytic powders. Today pulsation reactor technology has become established in chemical process engineering for manufacturing active particles with microstructural properties. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pulsation reactor」の詳細全文を読む スポンサード リンク
