Activity of Rhenium as a Methanation Catalyst
朴憲烈 중앙대학교 기술과학연구소 1981 기술과학연구소 논문집 Vol.8 No.-
Ultrahigh vacuum techniques have been employed to highly purify reactant gases and to prepare a clean Re filament for use of a methanation catalyst. The catalytic activity of CO-hydrogenation to produce methane have been investigated over a Re catalyst temperature range of 500-750k using 4H₂: 1CO at a total pressure of about 130 Torr(17KPa). The initial rate of CH₄synthesis over Re was lower than those of catalysta Ni and W. The observations of low catalytic activity over rhenium may have been due to inadequate surface cleaning procedures or due to the existence of impurities such as Fe and sulfur.
