Reactor channeling
Webreactor units based on microchannel technology are characterized by parallel arrays of microchannels, reducing heat and mass transfer distances, thus decreasing transfer … WebThere are three types of porosities used to describe a packed bed (a) Intraparticle porosity (εp): the fraction of the column volume occupied solvent inside the pores of the support or directly in contact with its surface (i.e., the stagnant mobile phase).

WebEffect of channeling in batch reactors. (a) Channeling diagram showing the regions in which the channeled reaction transforms the shown amount of the substrate (α[S] 0 ) faster or slower than the ... Webreaction system is most often used to catalyze gas reactions. This reactor has the same difficulties with temperature control as other tubular reactors; in addition, the catalyst is usually troublesome to replace. On occasion, channeling of the gas flow occurs, resulting in ineffective use of parts of the reactor
WebChanneling in single-phase flow can occur along walls or any other low voidage region, for example, if settling occurs in a horizontal bed. Channeling in two-phase flow can result from even more complex causes, and as seen simple two-phase flow theories seldom predict pressure drops in packed beds.
