Abstract: A process for hydrogenating a hydrogenatable organic compound in a reactor including a fixed catalyst bed. The fixed catalyst bed includes monolithic shaped catalyst bodies having pores and/or channels. The catalyst bodies include at least one element selected from Ni, Fe, Co, Cu, Cr, Pt, Ag, Au, Pd, Mn, Re, Ru, Rh and Ir. The CO content in the gas phase within the reactor during hydrogenation is within a range from 0.1 to 10,000 ppm by volume. In any section in the normal plane to flow direction through the fixed catalyst bed, at least 90% of the pores and channels have an area of not more than 3 mm2.
