Abstract
A catalyst comprising at least one alkali metal and at least one metallic or semimetallic promoter selected from the group consisting of Ca, Sr, Ba, Ag, Au, Zn, Cd, Hg, In, Tl, Sn, As, Sb and Bi, on a support which may be doped with one or more compounds of an alkali metal and/or alkaline earth metal, where the alkali metal/support ratio by weight is from 0.01 to 5, the promoter/alkali metal ratio by weight is from 0.0001 to 5 and, when a dopant is present, the dopant/support ratio by weight is from 0.01 to 5.
Claims4
A catalyst comprising at least (1) one alkali metal and (2) at least one metallic or semimetallic promoter selected from the group consisting of Ca, Sr, Ba, Ag, Au, Zn, Cd, Hg, In, Tl, Sn, As, Sb and Bi, on (3) a support which is optionally doped with (4) one or more alkali metal and/or alkaline earth metal compounds, where the alkali metal (1)/support (3) ratio by weight is from 0.01 to 5, the promoter (2)/alkali metal (1) ratio by weight is from 0.0001 to 5 and, when a dopant is present, the dopant (4)/support (3) ratio by weight is from 0.1 to 5, and wherein the alkali metal (1) is finely dispersed in metallic form on the support.
