    Abstract: The present invention relates to an integrated process for the synthesis of propylene oxide, which comprises at least the following steps: (i) dehydrogenation of propane to give a substream T( 0 ) comprising at least propane, propene and hydrogen; (ii) fractionation of the substream T( 0 ) to give at least one gaseous hydrogen-rich substream T( 2 ) and a substream T( 1 ) comprising at least propene and propane; (iii) synthesis of hydrogen peroxide using the substream T( 2 ), giving a substream T ( 4 ) which is rich in hydrogen peroxide and a gaseous substream T( 6 ); (iv) fractionation of the substream T( 1 ) to give at least one propane-rich substream T( 5 ) and at least one propene-rich substream T( 3 ); (v) reaction of the at least one substream T( 3 ) with substream T( 4 ) to give propylene oxide.

    Abstract: The present invention relates to the manufacture of solid materials or shape d bodies containing at least one zeolite and being at least partly crystalline . Furthermore, the present invention relates to the solid materials or shaped bodies as such and to the use of these materials for reactions of compounds having at least one C-C double bond with at least one hydroperoxide. Specifically, the present invention relates to a process for the manufacture of a solid material containing at least one zeolite and being at least partl y crystalline, wherein the synthesis of the said solid material involves at least one partial step of contacting at least one transition metal oxide source with at least one epoxide or hydrolysate thereof prior to or during t he at least partial crystallization of said solid material.

    Abstract: A process for regenerating a zeolite catalyst comprises the following stages: (I) Heating a partially or completely deactivated catalyst to 250-600° C. in an atmosphere which contains less than 2% by volume of oxygen, (II) treating the catalyst at from 250 to 800° C., preferably from 350 to 600° C., with a gas stream which contains from 0.1 to 4% by volume of an oxygen-donating substance or of oxygen or of a mixture of two or more thereof, and (III) treating the catalyst at from 250 to 800° C., preferably from 350 to 600° C., with a gas stream which contains from more than 4 to 100% by volume of an oxygen-donating substance or of oxygen or of a mixture of two or more thereof.
