摘要： The invention relates to a process (100) for deriving polymerizable aromatic compounds having nine carbon atoms (S) in which a component mixture (B) is formed at least partially by steam cracking, in which the component mixture (B) is subjected to a workup (2, 3, 4, 5) comprising a gasoline removal (5) and thereafter is a compression (8) and a fractionation (10), and wherein one or more pyrolysis gasoline fractions (H, L) is or are formed in the gasoline removal (5) and/or the compression (8). The invention provides that a separation feed is formed which comprises predominantly exclusively pyrolysis gasoline from the or at least one of the pyrolysis gasoline fractions (H, L) and that the separation feed is subjected to a separation (7), wherein in the separation (7) at least one fraction (P) enriched in aromatic compounds having nine carbon atoms compared to the separation feed is formed. A corresponding plant likewise forms part of the subject matter of the invention.

摘要： A process (100) is proposed for the production of one or more olefins, in which a reaction feed containing oxygen and one or more paraffins is formed and in which a part of the oxygen in the reaction feed is reacted with a part of the one or more paraffins to form the one or more olefins by an oxidative process, to obtain a process gas, the process gas containing at least the unreacted part of the one or more paraffins and oxygen, the one or more olefins, one or more acetylenes, carbon dioxide and water. The process comprises subjecting the process gas or a gas mixture formed using at least a part of the process gas partially or completely to a condensate separation (2), a compression (3), an at least partial removal (4) of the oxygen and acetylene(s) and to one or more stages of a carbon dioxide removal (5) in the order given herein, wherein the at least partial removal (4) of the oxygen and of the acetylene(s) is performed at the same time and by a catalytic conversion using a catalyst comprising copper oxide or ruthenium, and wherein the catalytic conversion is performed at least in part in the form of a hydrogenation. A corresponding plant is also the subject of the present invention.
