Porous kaolinitebeads were prepared by mixing kaolinitoe with various proportions of rice hull ash (RHA) and heating in a furnace at 800 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 kaolinire beads would be an excellent solid support matrix material for the utilization of biomass in biological fluidised bed (BFB) processes.
