Zeolite, manufacturing method of the same, and catalytic cracking catalyst of paraffin
A MSE-type zeolite which has a Si/Al ratio of 5 or more, is a proton-type zeolite, and is obtained by transforming a raw material MSE-type zeolite synthesized without using a structure directing agent into an ammonium-type zeolite through ion exchange, then, exposing the MSE-type zeolite to water vapor, and subjecting the exposed MES-type zeolite to an acid treatment.
1. A MSE-type zeolite which has a Si/Al ratio of 5 or more, is a proton-type zeolite, and is obtained by transforming a raw material MSE-type zeolite synthesized without using a structure directing agent into an ammonium-type zeolite through ion exchange, then, exposing the MSE-type zeolite to water vapor, and subjecting the exposed MES-type zeolite to an acid treatment.
2. The MES-type zeolite according to claim 1 ,
wherein the Si/Al ratio is 40 or more.
3. A catalytic cracking catalyst of paraffin including the MES-type zeolite according to claim 1 .
4. A manufacturing method of a MSE-type zeolite in which a raw material MSE-type zeolite is transformed into an ammonium-type zeolite through ion exchange, then, exposed to water vapor, and subjected to an acid treatment, thereby obtaining a MSE-type zeolite having an increased Si/Al ratio, wherein a MSE-type zeolite synthesized without using a structure directing agent is used as the raw material MSE-type zeolite to be ion-exchanged.
5. The manufacturing method according to claim 4 ,
wherein the ion-exchanged raw material MSE-type zeolite is exposed to water vapor at 150° C. to 1000° C. for 1 hour to 48 hours.
6. The manufacturing method according to claim 4 ,
wherein the raw material MSE-type zeolite which has been exposed to water vapor is subjected to an acid treatment at 40° C. to 100° C. for 1 hour to 24 hours using a mineral acid.
7. The manufacturing method according to claim 4 ,
wherein a MSE-type zeolite having a Si/Al ratio of 5 or more is obtained.
