The aim of this study was to perform sensitivity analysis, investigating how different fluidisation and sedimentation characteristics three-phase wetted UO2 powder beds, may affect a transient nuclear criticality excursion initiated through the addition water into fissile bed. This type postulated accident scenario occur in fuel fabrication facilities when fire is fought use water, supplied via...

Specifičan utjecaj biomase na proces odsumporavanja pri izgaranju smjese mrkog ugljena i biomase fluidiziranom sloju kotla. Rad je usmjeren na odreĎene aspekte procesa odsumporavanja u kotlovimas fluidiziranim slojem.Cilj studije bio je analizirati utjecaj nekoliko vrsta biomase na kvalitetu procesa odsumporavanja izgaranja smjese od mrkog ugljena, biomase i vapnenca u fluidiziranom sloju kotla...

A statistical model combined with CFD (computational fluid dynamic) method was used to explain the detailed phenomena of the process parameters, and a series of experiments were carried out for propylene polymerisation by varying the feed gas composition, reaction initiation temperature, and system pressure, in a fluidised bed catalytic reactor. The propylene polymerisation rate per pass was co...

Sorption-enhanced gasification (SEG) is a promising technology for producing renewable feedstock gas to be used in biofuel synthesis processes, especially dimethyl ether (DME) synthesis. To adopt the on commercial scale, it necessary acquire knowledge about related operational characteristics. The SEG process carried out at lower temperatures than those employed conventional gasifiers. A typica...

An integrated process for the primary capture of an intracellular enzyme, where cell disruption is directly coupled with ýuidised bed adsorption of the product, was proposed as a generic approach to beneüt the yield and molecular integrity of labile protein products. The puriücation of glyceraldehyde 3-phophate dehydrogenase (G3PDH) from waste brewers’ yeast was selected for the demonstration o...
