A traveling-wave reactor (TWR) is a proposed type of nuclear fission reactor that can convert fertile material into usable fuel through nuclear transmutation, in tandem with the burnup of fissile material.TWRs differ from other kinds of fast-neutron and breeder reactors in their ability to use fuel efficiently without uranium enrichment or reprocessing, instead directly using depleted uranium ...

Chemische Reaktionen finden in der Chemischen Reaktionstechnik in Reaktoren statt. Da die Hydrodynamik solcher Reaktoren äußerst kompliziert ist, werden diese Reaktoren idealisiert betrachtet. Dies nennt man Idealreaktor (abgekürzt IR).. Das bedeutet, dass mathematisch schwierig erfassbare reale Bedingungen, die in der Praxis jedoch immer in einem gewissen Rahmen vorhanden sind, z. B ...

The pebble-bed reactor (PBR) is a design for a graphite-moderated, gas-cooled nuclear reactor.It is a type of very-high-temperature reactor (VHTR), one of the six classes of nuclear reactors in the Generation IV initiative.The basic design of pebble-bed reactors features spherical fuel elements called pebbles. These tennis ball-sized pebbles are made of pyrolytic graphite (which acts as the ...

A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

The fluidized bed reactor is a reactor in which the fluid from the bottom of the reactor keeps the solid catalysts suspended inside the reactor. This reactor has an advantage over traditional packed bed reactor because it has a better heat and mass transfer. In industry, the fluidized bed reactor is most prominently used to produce products which cannot be efficiently manufactured using more ...

A bioreactor refers to any manufactured device or system that supports a biologically active environment. In one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms. This process can either be aerobic or anaerobic.These bioreactors are commonly cylindrical, ranging in size from litres ...

Trickle bed reactors are solid-liquid-gas contacting devices wherein a liquid stream flows downward over a bed of catalyst with pressure difference serving as the driving force . The fluid flows over catalyst particles and forms fine films, rivulets or droplets. The gas stream can either flow concurrent with the liquid or countercurrent to it through the bed. Trickle bed reactors are primarily ...

In manufacturing, the simulated moving bed (SMB) process is a highly engineered process for implementing chromatographic separation. It is used to separate one chemical compound or one class of chemical compounds from one or more other chemical compounds to provide significant quantities of the purified or enriched material at a lower cost than could be obtained using simple (batch ...

Nell'ingegneria chimica e nella chimica industriale, un reattore chimico è un contenitore progettato per farvi avvenire una reazione chimica. Esistono diverse tipologie di reattore chimico, in funzione della reazione da svolgervi e della natura chimica e delle sostanze coinvolte, nonché dalla modalità di conduzione della reazione: continua o discontinua (a lotti o batch).
