| 摘 要： | The influence of the type of alkali metal cations on the properties ofzeolite synthesized in a nonaqueous system was studied.The results indicatedthat different cations induced different topological structure of zeolite with thesame composition,and influenced the physicochemical and catalytic propertiesof zeolite in CO hydrogenation to light olefin.KNaZSM-48 and CsNaZSM-48supported iron catalysts had special activity for CO conversion and selectivity toC_2—C_4 olefins(64% and 61% respectively).
