Abstract: A process for preparing an amine by reacting an aldehyde and/or ketone with a nitrogen compound selected from the group consisting of ammonia and primary and secondary amines, and subsequent hydrogenation of the resulting reaction product in the liquid phase and in the presence of hydrogen and a heterogeneous copper oxide hydrogenation catalyst at a temperature of 20 to 230° C., wherein the aldehyde and/or ketone is reacted with the nitrogen compound either together with the hydrogenation in the liquid phase and in the presence of the hydrogen and of the catalyst (alternative 1) or in a step preceding the hydrogenation (alternative 2), and wherein the catalytically active composition of the catalyst, prior to reduction thereof with hydrogen, comprises at least 24% by weight of oxygen compounds of copper, calculated as Cu.

Abstract: The present invention relates to a process for purifying a crude nitrogen-containing, sulfur-containing, halogen-containing pyrolysis oil originating from the pyrolysis of plastic waste, comprising (i) subjecting the crude pyrolysis oil to a treatment with a trapping agent selected from (a) an elemental metal of group 1, 2, 6, 7, 8, 9, 10, 11, 12, 13 of the IUPAC periodic table, a mixture or an alloy thereof; (b) an oxide of metals of group 1, 2, 6, 7, 8, 9, 10, 11, 12, 13 of the IUPAC periodic table or a mixture thereof; (c) an alkoxide of metals of group 1, 2 of the IUPAC periodic table or a mixture thereof; (d) a solid sorption agent as defined in the claims; or a combination of at least two trapping agents (a), (b), (c) or (d); (ii) separating the product obtained into a purified pyrolysis oil fraction having a reduced nitrogen, sulfur and halogen content in relation to the crude pyrolysis oil and a fraction comprising the trapping agent which has bound at least a part of the sulfur, nitrogen, halogen present in the crude pyrolysis oil
