Defluidization Investigation into Bubbling Fluidized Bed Particles with Alkaline Addition during Pyrolysis

Some unwanted inorganic materials, such as alkaline compounds contained in biomass, have the potential to create slagging formations with oxide from either inside or outside bubbling fluidized bed (BFB). The process involved 88-125 µm silica sand and clay (bentonite) particles during pyrolysis KCl addition at 700°C represent biomass under superficialN 2 -velocity operation. Agglomeration formation was confirmed by decrease average ΔP of experiment, which theoretically should take place KCl, while defluidization condition a consistent particle deviation, even after further additions. Investigation 0.005 1 g encapsulated periodical showed that has tendency form agglomeration faster than bentonite, specifically 0.0211 (0.0032% total mass). Meanwhile, bentonite achieve more easily according deviation analysis. ability maintain fluidization longer indicates is better for this process.
