最近开发的具有立方烧绿石结构的铜-稀土氧化物催化剂（Cu-La 2 Zr 2 O 7）可用于CO + H2和CO2 + H2原料合成醇和烃。通过添加氧化物，例如，ZnO或ZrO 2。在过渡金属助剂Co的存在下，生成C2+醇和C2+烃。最后，通过将Cu-La_2 Zr_2 O_7甲醇催化剂与HY沸石混合制备的复合催化剂主要产生C2+烃。
The recent development of a copper-rare earth oxid catalyst (Cu-La2Zr2O7) with cubic pyrochlore structure allows to synthesize alcohols and hydrocarbons from CO + H-2 and CO2 + H-2 feeds. A good activity in methanol synthesis is obtained by promoting the given catalysts by addition of oxides, e.g., ZnO or ZrO2. C2+ alcohols and C2+ hydrocarbons are formed in the presence of a transition metal promotor like Co. Finally, a composite catalyst prepared by mixing the Cu-La2Zr2O7 methanol catalyst with a HY zeolite yields mainly C2+ hydrocarbons.
