International ClassC01B 035/10AbstractThis invention relates to a synthetic porous zeolite, identified as ZSM-57, a method for its preparation. This crystalline material may have a ratio of XO2 :Y2 O3 of at least 4, wherein X represents silicon and/or germanium and Y represents aluminum, boron, chromium, iron and/or gallium. The silica/alumina form of this crystalline material has a silica to alumina ratio of at least 4 and may be prepared with directing agents which are N,N,N,N',N',N'-hexaethylpentane-diammonium compounds. The crystalline material exhibits a characteristic X-ray diffraction pattern.Other References
