| 1. An alcohol synthesis catalyst comprising:
(a) at least one catalytically active metal or metal compound, active in producing alcohols from synthesis gas, and selected
from the group consisting of rhodium, manganese, cobalt, copper, and mixtures thereof; and
(b) a support for the at least one catalytically active metal or metal compound, wherein the support is an anionic clay comprising
a hydrotalcite clay with an average spherical diameter of up to about 60 μm and having the formula:
[M2+(1-x)M3+x(OH)2]x+(An−x/n)·mH2O,
wherein M2+ is a metal ion having a valence of 2+, M3+ is a metal ion having a valence of 3+, x is a number of about 0.10 to about 0.50, An− is an anion having a negative charge of n, and m is 0 or a positive number, and wherein M2+ and M3+ are different from said at least one catalytically active metal or metal compound, with the at least one catalytically active
metal or metal compound being on the support.
