PROCESS OF PRODUCING ZEOLITES FROM RICE HUSK ASH (RHA)

摘要

The present invention describes the process of synthesizing___ (LTA, beta_FAU, MFI, using CO2 as silicon source) by chemical method. Ash contains silicon and rice (tau pho cortex).The process described can be used for the production of cortical (Priest) rice production energy stove after ash combustion. It has the form of silicon crystal.An important stage of treatment is that the aqueous solution of sodium_can be dissolved at temperatures of 80 to 120 degrees Celsius. The crystal structure and the generated P, P, e, P, h, P, h, P, h, P, h, P, h, P, P, and so on. The solution is mixed with aluminum in aqueous solution, and appropriate recommendations.The crystallization temperature of zeolite is 85, stirring at 175 degrees Celsius. It also discloses the procedures that should be followed for the successful circulation mother liquor. Finally, the ability to remove cationic Ca2+ from drinking water and 89.7 56% between arcs from each stage mentioned in_____following LTA______has been demonstrated.
