Regenerating a Cobalt Acetate Catalyst
Quick Laboratory method:

$$\ce {CoCl2(aq) + 2NaOH(aq)-&gt;Co(OH)2(s) + 2NaCl(aq)}$$
$$\ce {Co(OH)2(s) + 2CH3CO2H(aq)-&gt;Co(CH3CO2)2(aq) + 2H2O(l)}$$
$$\ce {Co(CH3CO2)2(aq) + \Delta-&gt;Co(CH3CO2)2\cdot 4H2O (s)}$$

You should separate $\ce{Co(OH)2}$ by filteration and washed with water ($\pu {K_{sp} = 1.0 \times 10^{-15}}$) to remove all $\ce{NaCl}$ before subjected to react with $\ce{CH3CO2H}$.

This might work in industrial scale, if be careful. $\ce{Co(OH)2}$ is unstable to heat but no need to dry before react with $\ce{CH3CO2H}$.
