Abstract
A CATALYST CONSISTING OF THE OXIDES OF SILICON, ALUMINIUM AND TITANIUM, CHARACTERISED IN THAT THE CATALYST PARTICLES ARE BUILT UP FROM A CORE WITH THE COMPOSITION (8IO2) Y (ALO2) A, WHERE X/Y = 10 - 00 AND M = H, NA, K, NH4, NR4, WHEREIN R = CL-8-ALKYL, AND A SHEJL WITH THE COMPOSITION (8IO2)N(TIO2)M'' WHERE N/M = 12 -1000, AND BOTH THE CORE AND THE SHELL HAVE A CRYSTAL STRUCTURE OF THE MFI OR MEL TYPE. IT CAN BE PREPARED BY PREPARING A SYNTHESIS GEL FOR THE PREPARATION OF A TITANIUM SILICALITE IN A KNOWN MANNER, INTRODUCING AN ALUMINOSILICATE OF THE MFI OR MEL STRUCTURAL TYPE INTO THIS SYNTHESIS GEL AND WORKING UP THE SYNTHESIS GEL IN A KNOWN MANNER.
