摘要
Abstract
Magnified preparation of the catalyst was studied in this paper .Activity and stabili-ty of the catalyst were evaluated through long period ,and deactivation mechanism of the catalyst was studied .The study result showed that average conversion of CO and H2 reached 99 .9% and 99 .8% respectively ,average selectivity of CH4 attained 98 .5% ,and the activity of application catalyst was stable after continuous running of 1 000 hours .Deactivation mechanism study of the catalyst showed that the causes of catalyst deactivation with long period operation were carbon deposition and sintering ,in w hich sintering is the main factor resulting in the decrease of catalyst activity .关键词
