摘要:A mixed-bed catalytic system and its activation for direct synthesis of dimethyl ether from synthesis gas are described, comprising a catalyst for methanol synthesis and the zeolite ferrierite in its acid form as the methanol dehydrating component, the two being mixed physically in the form of powder of defined granulometry or as pellets. Another object of the present invention is a process for production of the acid form of the zeolite ferrierite. Another object of the present invention is a process for direct synthesis of dimethyl ether from a synthesis gas, using the catalytic system of the present invention.

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.
