摘要：

A series of bimetallic ruthenium and cobalt catalysts on a zeolite NaY support have been prepared and tested in carbon monoxide hydrogenation reaction. In all cases, C1-C6 hydrocarbons were formed. Selectivity shifted towards lower molecular weights (<C4) with increasing cobalt content. The presence of cobalt caused a decrease in overall catalytic activity but enhanced stability with time-on-stream. Increased methane rates at intermediate metal compositions may be the result of modified adsorbate coverages due to ruthenium-cobalt interactions.
