Process for epoxidation and catalyst to be used therein
First Claim
1. A process for treating a solid material or a shaped body comprising at least one zeolite, and being at least partly crystalline, wherein said solid material or the shaped body is brought in contact with a composition comprising waters after at least one of the following steps of an integrated process for producing a solid material or a shaped body:
- (i) after step (II) of separating the at least partly crystalline solid material from its mother liquors or (ii) after step (S) of shaping said solid material into a shaped body, or (iii) after a step (C) of calcining said solid material or said shaped body.

Abstract
The present invention relates to a process for treating a solid material containing at least one zeolite and being at least partly crystalline or treating a shaped body obtained from said solid material wherein said solid material or shaped body is brought in contact with a composition containing water after at least one of the following steps of an integrated process for producing a solid material or a shaped body containing at least one zeolite: (i) after step (II) of separating the at least partly crystalline solid material from its mother liquor or (ii) after step (S) of shaping said solid material into a shaped body or (iii) after a step (C) of calcining said solid material or said shaped body. The present invention furthermore relates to the solid material obtainable by the inventive process and the shaped body obtainable by the inventive process. The present invention finally relates to the use of the solid material or the shaped body as mentioned above as a catalyst in chemical reactions, in particular in reactions of compounds containing at least one C—C double bond with at least one hydroperoxide.

7. An integrated process for the production of a solid material, comprising at least one zeolite, said process comprising at least the following steps:
-
(I) crystallizing, at least partially, at least one solid material comprising at least one zeolite, out of a synthesis mixture, resulting in mixture (I) comprising at least said solid material and a mother liquor;
(II) separating and/or concentrating the solid material in mixture (I);
(W) contacting the solid material from step (II) with a composition comprising water;
(III) agglomerating or granulating or agglomerating and granulating the solid material from step (W);
wherein step (III) is optional. - View Dependent Claims (8, 9, 13, 14, 27, 28)

10. The integrated process for the production of a shaped body comprising at least one zeolite, said process comprising at least the following steps:
-
(I) crystallizing at least partially, at least one solid material comprising at least one zeolite, out of a synthesis mixture, resulting in mixture (I) comprising at least said solid material and a mother liquor;
(II) separating and/or concentrating the solid material in mixture (I);
(W) contacting the solid material from step (II) with a composition comprising water, (III) agglomerating or granulating or agglomerating and granulating the solid material from step (W);
wherein step (III) is optional, and wherein, after step (W), or after step (III), at least one step (S) of shaping the solid material into a shaped body is performed. - View Dependent Claims (11, 12, 29, 30, 31)

34. A shaped body comprising a solid material comprising at least one zeolite, and being at least partly crystalline, obtained by a process comprising the steps of:
-
(I) crystallizing, at least partially, the at least one solid material comprising at least one zeolite, out of a synthesis mixture, to form a mixture (I) comprising at least the solid material and a mother liquor;
(II) separating and/or concentrating the solid material in mixture (I);
(S) shaping the solid material into a shaped body;
(C) calcining the shaped body at temperatures higher than 400°
C., to form a calcined shape body;
(W) contacting the calcined shaped body with a composition comprising water; and
wherein the separation and/or concentration in step (II) is carried out by a method selected from the group consisting of;
filtration, ultrafiltration, diafiltration, centrifuge methods, spray drying and spray granulating; and
wherein the shaping of the solid material in step (S) is carried out by a method selected from the group consisting of;
pelletizing, pressing, extruding, sintering, roasting and briquetting. - View Dependent Claims (35, 36, 37, 38)
