SYNTHESIS OF ZEOLITE NaA AND ACTIVATED CARBON COMPOSITE FROM RICE HUSK
Keywords:
Zeolite NaA, rice husk charcoal, activated carbon, compositeAbstract
Rice husk charcoal, composed of SiO2 39%, K2O 1.18%, and L.O.I. 58.50% weight basis, was prepared by burning rice husks (obtained from Klong 6 Rice Mill, Lumlookka, Patumthani, Thailand) in an incineration furnace below 700oC which was used as an SiO2 source for the synthesis of zeolite NaA and carbon composite under hydrothermal conditions. The prepared powders were formed into pellets with 25 mm diameters by hydraulic pressing at 40 MPa. The pellets were activated in N2 atmosphere at 300-700oC for 1 h. Phase analysis, morphology, and specific surface area of the synthesized pellets were characterized using X-ray diffraction, scanning electron microscopy, and the Brunauer-Emmett-Teller technique, respectively.
