Moving bed reactors
NettetThe moving-bed reactor can be considered when a compact high-rate system is needed to meet basic secondary treatment standards. In high-rate applications, the MBBR is operated under high SARL conditions, with the main purpose of removing the soluble and easily degraded BOD from the influent stream. Nettet22. feb. 2016 · Moving Bed Reactors; A moving bed reactor is similar to a radial flow reactor, but the catalyst is moved through the annular space (Towler, 2012). Fluidized Bed Reactors; If the fluid flow is up through the catalyst bed then the bed can become fluidized if the pressure drop is high enough to support the weight of the catalyst.

Nettet5. mar. 2024 · Moving bed reactors are another widely explored reactor type for CO 2 capture as an alternative to fixed bed reactors. Fundamentally, moving beds behave similarly to fixed beds, with the primary benefit being that the moving particle bed allows for steady state operation. NettetIn a moving-bed gasifier, a bed of solid fuel moves slowly downwards. A characteristic of this type of gasifier is the formation of four zones (drying, pyrolysis, oxidation, and reduction). The reactors can be operated as updraft or downdraft gasifier depending on the location of the feeding point for the gasifying agent.
