A process for the production of a zeolitic material having an LEV-type framework structure comprising YO2 and optionally comprising X203, wherein said process comprises preparing a mixture comprising one or more sources for YO2, one or more solvents, and optionally comprising seed crystals; and crystallizing the mixture; wherein Y is a tetravalent element, and X is a trivalent element, and wherein the crystallized mixture contains 0.1 wt.-% or less, more preferably 0.01 wt.-% or less of one or more metals M based on 100 wt.-% of YO2, wherein even more preferably the crystallized mixture contains no metal M, wherein M stands for sodium and/or potassium, wherein preferably M stands for the group of alkali and alkaline earth metals.

Alkali-free synthesis of zeolitic materials of the LEV-type structure

The present invention relates to a process for the preparation of a zeolitic material having a CHA framework structure, said zeolitic material comprising zeolite crystals having a core-shell structure, wherein said process comprises the steps of

The present invention relates to a process for the alkylation of an organic compound comprising: (a) providing a catalyst comprising one or more zeolitic materials having a BEA framework structure, wherein the BEA framework structure comprises YOand optionally comprises XO, wherein Y is a tetravalent element, and X is a trivalent element, (b) contacting the catalyst with one or more alkylatable organic compounds in the presence of one or more alkylating agents in one or more reactors for obtaining one or more alkylated organic compounds, wherein the one or more zeolitic materials is obtainable from a synthetic process which does not employ an organotemplate as structure directing agent.

Process for the alkylation of organic compounds

The present invention relates to a process for the preparation of a zeolitic material having a BEA framework structure comprising the steps of: (i) providing one or more zeolitic materials having a BEA framework structure, wherein the BEA framework structure comprises YOand XO, wherein Y is a tetravalent element, and X is a trivalent element; (ii) subjecting the one or more zeolitic materials provided in step (i) to a procedure for removing at least a portion of X, preferably tetrahedrally coordinated X, from the BEA framework structure; wherein the Y:X molar ratios of the one or more zeolitic materials provided in step (i) are respectively comprised in the range of from 1 to 50.
