Synthesis of zeolite ZSM-48 from rice husk ash

Zeolite ZSM-48 with a very high crystallinity (99% +) can be synthesized from a reaction mixture containing a silica source from rice husk gasification ash. The difference in the cracking behavior of n-hexane for zeolites ZSM-5 and ZSM-48 may be attributed to the unique two-dimensional channel struc...

Description
Summary:Zeolite ZSM-48 with a very high crystallinity (99% +) can be synthesized from a reaction mixture containing a silica source from rice husk gasification ash. The difference in the cracking behavior of n-hexane for zeolites ZSM-5 and ZSM-48 may be attributed to the unique two-dimensional channel structure for the ZSM-48. The ammonia desorption data also indicate that the influence of the channel system of ZSM-48 could play an important role in the molecular traffic control.
