专利号:EP-4353356-A1 优先权日:2022-10-14 标题:Bifunctional catalyst formulation for synthesis of dimethylether (dme) from waste carbon dioxide and hydrogen by one-step and the synthesis method thereof 发明人:SEKER EROL; ZAHIDOVA AYSEL; MUTLU VAHIDE NURAN; DELIISMAIL OZGUN; SARRAFI SAHIN; TUNCER BASAK 权利人:SOCAR TURKEY ARASTIRMA GELISTIRME VE INOVASYON A S; IZMIR YUKSEK TEKNOLOJI ENSTITUSU REKTORLUGU 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.
