Abstract
The present invention concerns a process for synthesising a zeolite with structure type MTT comprising at least one element X selected from silicon and germanium and at least one element T selected from aluminium, iron gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese, comprising reacting an aqueous mixture comprising at least one source of at least one element X, at least one source of at least one element T, and at least one precursor of an organic compound comprising at least one alkylated polymethylene &agr;-&ohgr; diammonium derivative, characterized in that at least one precursor is selected from monoamines. The present invention also concerns the use of the zeolite obtained as a catalyst in a process for converting hydrocarbon-containing feeds, as an adsorbent to control pollution and as a molecular sieve for separation.
