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

摘要

PROBLEM TO BE SOLVED: To provide a relatively large zeolite bulk body capable of being worked to an optional form by machining.SOLUTION: The machinable zeolite bulk body in which no binder is used related to the present invention is composed of 50 to 100 mass% of a zeolite component (A) and 50 to 0 mass% of a silica component made of α-SiOand/or amorphous SiO(B), the zeolite component (A) being hydrophilic with Si/A ratio of 1 or more and less than 3. The machinable zeolite bulk body has a tensile strength of 3 MPa or more or a flexure strength of 3 MPa or more.SELECTED DRAWING: Figure 11
