- - Method for manufacturing of meso-microporous mordenite in form of plate and meso-microporous mordenite in form of plate thereby

摘要

The present invention relates to a method for producing meso-microporous plate-like mordenite and meso-microspheroidal plate-like mordenite produced thereby, and more particularly to a mordenite precursor having a molar ratio of SiO ₂ / Al ₂ O ₃ of 25 to 35 A manufacturing step (step 1); Mixing the mordenite precursor of step 1 with a casting mold (step 2); Crystallizing mordenite in the mixed solution of step 2 (step 3); And a step (4) of heat-treating the crystallized mixed solution of step 3 to remove the cast body (4), and a method for producing the meso-microspheroidal plate-like mordenite. The present invention can produce a mordenite having a plate-like shape at the same time as the plate-shaped meso-micropores by a simple method. At this time, since an inexpensive surfactant or a hydrophilic polymer is used and organic silane is not added, it can be economically provided because it is commercially available. In addition, there is an effect that the catalyst can be used as an excellent and stable catalyst capable of maintaining a high conversion rate for a relatively long time without shape-selective and deactivation in molecular conversion reaction.
