Porous kaolinite bead: a novel but economical solid support material for biomass in fluidised bed technology

Porous kaolinite beads were prepared by mixing kaolinite with various proportions of rice hull ash (RHA) and heating in a furnace at 800 degree C. for five hours. Those with 10 to 60% (w/w) RHA were very porous and had good mechanical strength. The raw materials were inexpensive and their preparatio...

Description
Summary:Porous kaolinite beads were prepared by mixing kaolinite with various proportions of rice hull ash (RHA) and heating in a furnace at 800 degree C. for five hours. Those with 10 to 60% (w/w) RHA were very porous and had good mechanical strength. The raw materials were inexpensive and their preparation relatively simple, therefore these porous kaolinite beads would be an excellent solid support matrix material for the utilization of biomass in biological fluidised bed (BFB) processes. The binding of microorganisms to the particles would be straightforward, expecially with biomass containing a mixed population of cells.
