摘要:The invention relates to a catalytically active body for the synthesis of dimethyl ether from synthesis gas. In particular, the invention relates to an improved catalytically active body for the synthesis of dimethyl ether, whereby the components of the active body comprise a methanol active component and an acid component comprising a zeolitic material being crystallized by means of one or more alkenyltrialkylammonium cation R 1 R 2 R 3 R 4 N + -containing compounds as structure directing agent. Furthermore, the present invention concerns a method for the preparation of a catalytically active body, the use of the catalytically active body and a method for the preparation of dimethyl ether from synthesis gas.

摘要:Provided herein is a method for the preparation of ionizable, cationic amino lipids using a doubly alkylated nucleophilic intermediate to produce a ketone. The ketone, or a corresponding alcohol, is subjected to one or more synthesis steps to add an ionizable moiety thereto. The method can be advantageously employed for the synthesis of unsymmetrical analogues of the above lipids that would be considerably more difficult to make by alternative strategies. The method can also be used to prepare symmetrical ionizable, cationic amino lipids with fewer steps and/or with the use of fewer hazardous chemicals than known synthesis methods.

摘要:Synthesis of aromatic hydrocarbons from synthesis gas in a fixed bed or a moving bed reactor loaded with a composite catalyst comprising Catalyst Component A and Catalyst Component B mixed via a mechanical mixing mode, wherein the active ingredient of the Catalyst Component A is active metal oxides; and the Catalyst Component B is one or both of ZSM-5 zeolite and metal modified ZSM-5; the pressure of the synthesis gas is 0.1-6 MPa; the reaction temperature is 300-600° C.; and the space velocity is 500-8000 h −1 . The reaction process has a high product yield and selectivity, with the selectivity of aromatics reaching 50-85%, while the selectivity of the methane byproduct is less than 15%.

摘要:This invention relates to bifunctional catalyst formulation for synthesis of dimethyl-ether (DME) from waste carbon dioxide (CO₂) and hydrogen (H₂) and the preparation method of this catalyst formulation. In the preparation method, aluminum oxide-silicon dioxide-copper oxide (Al₂O₃-SiO₂-CuO) catalyst mixture formulation is obtained by using the sol-gel method. The catalysts that are the subject of the invention are bifunctional and perform the synthesis of DME from CO₂ and H₂ in a single-step without forming unwanted byproduct of CH₄, and thus, the synthesis of DME can be done much simply and economically. In addition to this, the sol-gel method in the current invention yields the controlled crystallite size of the active component in the catalysts; thus, the active site loss problem due to uncontrolled growth of crystal sizes that occurs in traditional preparation methods is prevented. The catalyst mixture formulation weight percentages are 10%-90% Al2O₃, 10%-90% SiO₂ and 10%-90% CuO.

摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.
