Prepn. of new titanium-beta zeolite cpd.

摘要

The prepn. of a new Ti-Beta zeolite comprises: (a) impregnation of a cogel, comprising at least one amorphous titano-silicate (TiO2-SiO2) with a soln. comprising at least one structuring and mobility agent; a trivalent element source is used either in the cogel or in the impregnating source; (b) heating of the reaction mixt. to the crystallisation point of the zeolite; and (c) recovery and calcination of the zeolite obtd. Also claimed is the prod. and its use as a selective oxidn. catalyst.
