Abstract

Rice husk (RH) and carbonaceous rice husk ash (CRHA) have been used as source of silica for the synthesis of NaA zeolite. It was demonstrated that the NaA zeolite can be synthesized directly from RH and CRHA. First, RH and CRHA samples were submitted to a chemical pretreatment using NaOH solution and then followed by mixing with aluminates solutions, and maintaining the mixture at temperature of 100 oC for 5 hours. The experimental results show that the quality of NaA zeolite from CRHA is higher than that of RH, because there is the tendency the formation of amorphous phases in NaA zeolite from RH.
