Process for the preparation of X-and P-type zeolites using natural mordenite-based minerals

摘要

The present invention relates to a method for producing X-and P-type zeolites using natural mordenite-based minerals, that is, plowing rocks. The natural mordenite-based mineral containing a large amount of impurities is calcined at 600 to 1000C for about 4 hours to enhance the reactivity with NaCl or NaOH, unlike the case where the reaction is carried out at a high temperature of about 120C After the reforming, NaOH or NaOH to NaCl are added and reacted at a relatively low temperature of 90 to 100C. Thus, X-form and P-type, which can be utilized for catalysts of high added value, ion exchangers, Type zeolite.
