METHOD FOR THE PRODUCTION OF A TITANIUM-CONTAINING ZEOLITE

摘要

THE PRESENT INVNETION CONCERNS A METHOD FOR THE PRODUCTION OF A TITANIUM-CONTAINING ZEOLITE WHEREBY A SYNTHESIS GEL IS FORMED BY COMBINING AND HYDROLYSING A HYDROLYSABLE SILICON COMPOUND, A HYDROLYSABLE TITANIUM COMPOUND AND A BASIC QUATERNARY AMMONIUM COMPOUND IN AN AQUEOS MEDIUM, IN QUANTITIES SUCH THAT RELATIVE TO THE STARTING COMPOUNDS THE MOLAR RATIOO OF Si/TI IS GREATER THAN EQUAL TO 300 AND THAT OF N/Si IS 0.112 TO LESS THAN 0.20, NAD THE SYNTHESIS GELL IS THEN CRYT STALLISED AT A TEMPERATURE OF 150°C TO 220°C FOR A PERIOD OF LESS THAN 3 DAYS, AND A TITANIUM-CONTAINING ZEOOLITE OBTAINABLE BY THIS METHOD.
