The synthesis of olefins from dimethyl ether (DME) on a hydrothermally treated Mg-HZSM-5/Al2O3 catalyst in artificial synthesis gas atmospheres was studied. The study was carried out on a micropilot unit in a flow mode at 0.1 MPa and 320 °C. The use of synthesis gas with different hydrogen concentration as a diluent did not decrease selectivity for the formation of C2–C4 olefins. The formation of alkanes occurred only in H-transfer reactions without the participation of molecular hydrogen.

在合成气气氛中由二甲醚合成烯烃

研究了在人工合成气体气氛下,在水热处理的Mg-HZSM-5 / Al 2 O 3催化剂上由二甲醚(DME)合成烯烃的方法。该研究是在微型先导装置上以0.1 MPa和320°C的流动模式进行的。使用具有不同氢浓度的合成气作为稀释剂不会降低形成C 2 -C 4烯烃的选择性。烷烃的形成仅在氢转移反应中发生,而没有分子氢的参与。
