Adsorption of Methane on the Pt/Al2O3 Catalyst. Studying of Reactionary Activity of the Adsorbed Methane Forms in Reaction of Joint Transformation with N Pentane

It is shown in the work that in the presence of the preadsorbed hydrogen forms on the catalyst 1%Pt/Al2O3 the maximum size of adsorption of methane at 823K makes 1,1 CH4/Pt of mol/mol. Existence on the surface of the preadsorbed oxygen leads to emergence in the reactionary environment 0,6mol. CO, an...

Description
Summary:It is shown in the work that in the presence of the preadsorbed hydrogen forms on the catalyst 1%Pt/Al2O3 the maximum size of adsorption of methane at 823K makes 1,1 CH4/Pt of mol/mol. Existence on the surface of the preadsorbed oxygen leads to emergence in the reactionary environment 0,6mol. CO, and the total of the turned methane makes 1,3 CH4/Pt of mol/mol. On the catalyst surface (in lack of the preadsorbed forms of hydrogen and oxygen) the amount of the adsorbed methane decreases to 0,8 CH4/Pt mol/mol. Studying of reactionary ability of the adsorbed methane forms in reaction of joint transformation with N pentane shows quite high catalytic activity of alkanes in the formation of aromatic hydrocarbons.
