<p>catalysts for the hydrogenolysis of org. S cpds. in refinery gases, are partially poisoned to inhibit methanation and sooting. This is achieved by pre-soaking in alkali-free solutions contg. 2.5-25% SO4" (pref. H2SO4, (NH4)2SO4, or NiSO4), followed by vacuum treatment and drying at 110 degrees C.</p> |
