Disclosed herein is a continuous process for preparing zeolitic material with a CHA-type framework structure comprising SiOand XOand the zeolitic material so-obtained. The processes comprises (i) preparing a mixture comprising one or more sources of SiO, one or more sources of XO, seed crystals, one or more tetraalkylammonium cation RRRRN-containing compounds as structure directing agent, and a liquid solvent system; (ii) continuously feeding the mixture prepared in (i) into a continuous flow reactor at a liquid hourly space velocity; and (iii) crystallizing the zeolitic material with a CHA-type framework structure from the mixture in the continuous flow reactor.

The present invention relates to a catalyst based on iron oxide for the dehydrogenation of hydrocarbons and also a process for producing it. The catalyst comprises at least one iron compound, at least one potassium compound and at least one cerium compound, wherein the at least one iron compound and the at least one potassium compound are at least partly present in the form of one or more K/Fe mixed oxide phases of the general formula KFeO, where x is from 1 to 17; y is from 1 to 22 and z is from 2 to 34, where the catalyst comprises at least 20% by weight, based on the total catalyst, of the K/Fe mixed oxide phases and comprises crystalline cerium dioxide having a crystallite size in the range from 10 nm to 30 nm.

Catalyst for dehydrogenating hydrocarbons

The present invention relates to a process for recovering oil from a subterranean formation by injecting both solid particles and water into the formation. An oil-in-water emulsion that is stabilized by solid particles is formed in the pores of the formation. This emulsion is recovered from the subterranean formation.

The invention relates to a nickel hexaaluminate-comprising catalyst for reforming hydrocarbons, preferably methane, in the presence of carbon dioxide, which comprises hexaaluminate in a proportion in the range from 65 to 95% by weight, preferably from 70 to 90% by weight, and a crystalline, oxidic secondary phase selected from the group consisting of LaAlO, SrAlOand BaAlOin the range from 5 to 35% by weight, preferably from 10 to 30% by weight. The BET surface area of the catalyst is &#x2267;5 m/g, preferably &#x2267;10 m/g. The molar nickel content of the catalyst is &#x2266;3 mol %, preferably &#x2266;2.5 mol % and more preferably &#x2266;2 mol %. The interlayer cations are preferably Ba and/or Sr. The process for producing the catalyst comprises the steps: (i) production of a mixture of metal salts, preferably nitrate salts of Ni and also Sr and/or La, and a nanoparticulate aluminum source, (ii) molding and (iii) calcination. The catalyst of the invention is brought into contact with hydrocarbons, preferably methane, and COin a reforming process, preferably at a temperature of &#x3e;800&#xb0; C. The catalyst is also distinguished by structural and preferred properties of the nickel, namely that the nickel particles mostly have a tetragonal form and the particles have a size of &#x2266;50 nm, preferably &#x2266;40 nm and particularly preferably &#x2266;30 nm, and are present finely dispersed as grown-on hexaaluminate particles. The catalyst has only a very low tendency for carbonaceous deposits to be formed.
