Abstract

M_{0.5(1 +x)}Fe_xZr_{2 –x}(PO₄)₃ (M = Ni, Cu, Mn; 0 ≤ x ≤ 0.5) phosphates have been studied as catalysts for methanol conversion in the temperature range 200–450°C. The results demonstrate that the most active and selective catalysts among these materials are Ni_0.5Zr₂(PO₄)₃ and Cu_0.65Fe_0.3Zr_1.7(PO₄)₃. The dimethyl ether yield on the synthesized materials is comparable to that on available commercial catalysts.

摘要

中号_{0.5（1 + X）}的Fe _X的Zr _{2 - X}（PO ₄）₃（M =镍，铜，锰，0≤ X ≤0.5）的磷酸盐已被研究作为催化剂用于在所述温度范围200-450甲醇转化° C。结果表明，在这些材料中，最具活性和选择性的催化剂是Ni _0.5 Zr ₂（PO ₄）₃和Cu _0.65 Fe _0.3 Zr _1.7（PO ₄）₃。合成材料上的二甲醚产率与市售催化剂上的相当。
