溶剂化金属原子浸渍法制备AlPO_4-5载铁等金属催化剂的表征和催化性质

CHARACTERIZATION AND CATALYTIC FEATURE OF AIPO_4-5 SUPPORTING IRON AND OTHER METALS CATALYSTS PREPARED VIA SOLVATED METAL ATOM IMPREGNATION

用金属蒸气合成制备了A1PO_4-5负载铁等金属催化剂。用原子吸收、XRD、磁测定和XPS对催化剂进行了表征。催化CO+H_2反应生成的烃类的碳原子数小于5。K、La可提高烯烃生成的选择性。

AlPO_4-5 supporting iron and other metals catalysts were prepared by Metal Vapor Synthesis (MVS). The catalysts were characterized with atomic absorption spectrometry, XRD, magnetic measurement and XPS. The carbon number of products in catalytic reduction of CO by H_2 to hydrocarbons is less than five. Potassium and lanthanum increase the selectivity of olefin formation.
