Synthesis and structure of synthetic zeolite ZSM-11
Abstract
ZSM-5 (refs 1, 2) is a member of a new class of shape selective catalysts which have unique channel structures with 10-membered ring openings. These catalysts have unusual properties. They can selectively convert methanol to high quality gasoline3-6 and are used in commercially significant processes, such as distillate dewaxing, ethylbenzene synthesis, xylene isomerisation and toluene disproportionation5,7 The framework of ZSM-5 (ref. 2) contains a novel configuration of linked tetrahedra consisting of eight five-membered rings. These configurational units may be linked through edges to form chains and the chains to form a three-dimensional framework which describes an intersecting channel system with openings intermediate between those in zeolite Linde type A and faujasite. We report here the synthesis and structure of another member of this family, ZSM-11.
