Abstract
Abstract A synthetic zeolite material, designated zeolite Nu-13, is a member of the ZSM-12 family of zeolites and is prepared from an aqueous reaction mixture containing the oxide X0 2 , the oxide Y 2 0 3 and a piperazine compound where X is silicon or germanium and Y is aluminium, gallium, boron, iron, chromium, vanadium, molybdenum, arsenic, antimony or manganese.
