SYNTHETIC METHANOL CATALYSTS - COMPETITIVE CO(CO2)-H-2-OLEFIN REACTIONS

Systematic studies of the transformation of olefin/CO(CO//2)/H//2 mixtures on methanol catalysts (A: CuO/ZnO; Cr//2O//3/ZnO) have clearly shown that, even in the presence of CO (or CO//2), copper-based catalysts are active in the hydrogenation of olefins. This confirms that the proportion of olefins obtained by the direct transformation of CO/H//2 mixtures on composite catalysts, consisting of the association of a methanol catalyst (A) and a mordenite (B), is intimately related to the hydrogenative ability of the former (A).
