MACHINABLE ZEOLITE BULK BODY, METHOD FOR PRODUCING SAME AND HYDROTHERMAL SYNTHESIS REACTION SOLUTION THEREFOR, AND APPLICATION THEREFOR

• 特願2011-055816 (2011.3.14) JP

This machinable zeolite bulk body, in which no binder is used, is characterized in comprising 50-100 mass% of a zeolite component (A) and 0-50 mass% of a silica component (B) made of a-SiO2 and/or amorphous SiO2, the tensile strength thereof being at least 3 MPa or the flexural strength thereof being at least 3 MPa. This zeolite bulk body can be either hydrophobic (Si/Al ratio at least 3) or hydrophilic (Si/Al ratio ranging from 1 to less than 3), and can be produced by running a hydrothermal synthesis treatment for 6 hours to 10 days at a temperature of 80-225 DEG C on a hydrothermal synthesis reaction solution containing a silica source (a), and, per mole of silica (SiO2) in the silica source: 0.1-3.0 moles of an alkali metal component (b), in terms of the amount of alkali metal atoms

0-0.7 moles of an alumina source (c), in terms of the amount of alumina (Al2O3)

0-0.15 moles of an organic template (d)

and 5-50 moles of water (e).
