Abstract (en)
[origin: US4309271A] Hydrocarbons are subjected to hydrogenation, pressure reduction and separation into liquid and gaseous fractions. The gaseous fractions are purified and desulfurized. Hydrogen-rich components of the gaseous fraction are returned to the hydrogenation stage. Hydrocarbon-rich components of the gaseous fraction and components of the liquid fraction are cracked and fractionated. Residue is partially oxidized with oxygen and steam. Gas produced by the partial oxidation is desulfurized and separated, and hydrogen is returned to the hydrogenation stage. A polymer free fraction of the residue is returned to the feed stock and to the hydrogenation stage, a heavy residue component of the initial liquid fraction is partially oxidized with the residue.
Abstract (de)
Das Vertahren zum Spalten von Kohlenwasserstoffen kann bei der thermischen Spaltung (9) schwerer Kohlenwasserstoffe, die einer hydrierenden Vorbehandlung (2) unterzogen werden, angewendet werden Der Pyrolyserückstand (14) der thermischen Spaltung (9) wird durch partielle Oxidation (15) vergast. Der dabei gebildete Wasserstoff wird abgetrennt (19, 21) und der hydrierenden Vorbehandlung (2) zugeführt. Bei einer Abtrennung polymerer Bestandteile des Pyrolyserückstandes (14) werden nur diese vergast, während die nicht polymeren Komponenten zur Hydrierung (2) zurückgeführt werden.
