<p>A process is for the reductive deoxygenation of oxo gp.-contg. organic cpds. (I) by reaction with heterogeneous redox catalysts (II) in their reduced or partly reduced form, in the gas phase at elevated temp. comprises (a) continuous deoxygenation alternating (in time or space) with reductive regeneration of (II) under non-steady state conditions, i.e. cpds. (I) are contacted with (II) in such a way that catalyst which still retains its deoxygenating action is present at the outlet from the deoxygenation zone, and (b) regeneration of the used (II) by redn. at elevated temp. with hydrogen, CO, hydrocarbons, ammonia NO and SO2, (c) using a redox catalyst (II) which, in its oxidised form, contains oxide(s) of Bi, V, Cr, Mn, Ti, U, Fe, Co, Pb, Mo, Ce, Sn, Sb and/or Cu.</p> |
