Aluminosilicate of utd-1 structure type

摘要

The invention provides a crystalline aluminosilicate and process for its preparation, a crystalline borosilicate intermediate and process for its preparation, a catalyst composition containing the aluminosilicate and process for converting a hydrocarbonaceous feedstock using the catalyst composition, the aluminosilicate having in its calcined form a silicon to aluminium bulk molar ratio in the range from 10 to 50 and an X-ray diffraction pattern including values substantially as set forth in the table (a).
