A process for producing high-purity hydrotalcites by reacting alcohols or alcohol mixtures with at least one or more divalent metal(s) and at least one or more trivalent metal(s) and hydrolysing the resultant alcoholate mixture with water. The corresponding metal oxides can be produced by calcinatio

The method of claim 1 wherein the inlet temperature is controlled such that the reactor maximum temperature is approximately equal to the adiabatic temperature, the reactor maximum temperature occurring proximate to the reactor exit. 3. The method of selectively oxidizing carbon monoxide in a gas stream comprising carbon monoxide, hydrogen and oxygen, the gas stream having an inlet temperature and an adiabatic temperature, within an adiabatically-operated, fixed-bed catalytic reactor having a catalyst suitable for promoting oxidation of carbon monoxide and an exit, the reactor capable of cooperating with the gas stream to achieve a space velocity, the method comprising: adjusting the inlet temperature as a function of the space velocity. 4. The method of claim 3 wherein the inlet temperature is controlled such that the reactor maximum temperature is approximately equal to the adiabatic temperature, and the reactor maximum temperature occurs proximate to the reactor exit.
