    • The invention relates to producing a silicate containing at least one type of silicium and oxygen consisting (1) in mixing silicium dioxide and/or silicium dioxide precursors with an aqueous solution, which comprises at least one type of R 1 R 2 R 3 R 4 N + compound containing a tetra-acryl ammonium compound and at least one type of base, wherein R 1 and R 2 represent methyl and, at the same time, R 3 and R 4 represent n-propyl; (2) in heating the colloidal solution thus obtained with a temperature greater than a boiling temperature at a selected colloidal solution pressure up to 180 °C at a normal pressure in such a way that at least one type of silicate-containing suspension is obtained. Said invention is characterised in that the silicium and oxygen-containing silicate is added in the form of a crystallisation-assisting agent.

    • The invention relates to a method for producing propene from propane. Said method comprises the following steps: A) a feed gas stream (a) containing propane is prepared; B) the feed gas stream (a) containing propane, is introduced with optionally water vapour and optionally, an oxygen-containing gas stream into a dehydrogenation zone and then the propane is dehydrogenated to form propene, and a product gas stream (b) containing propane, propene, methane, ethane, ethene, hydrogen, optionally carbon monoxide, carbon dioxide, water vapour and oxygen, is obtained; C) the product gas stream (b) is cooled, optionally compressed and then water vapour is separated by condensation and a product gas stream (c) depleted in water vapour is obtained; D) the product gas stream (c) is brought into contact with a selectively active adsorber which selectively adsorbs propene in the selected adsorption conditions, and an adsorber charged with propene and a gas stream (d2) depleted in propene and containing propane, methane, ethane, ethene and hydrogen, carbon monoxide and carbon dioxide are obtained; E) a gas stream (e1) containing propene is released from the adsorber charged with propene by reducing the pressure and/or heat of the adsorber.
