Abstract:
The present invention relates generally to methods for producing renewable detergent compounds. More specifically, the invention relates to methods for producing detergent intermediates, including bio-linear alkylbenzene (LAB), bio-alcohols, and long chain bio-paraffins, from natural oils.
Abstract:
Integrated systems are provided for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compositions, from methane using an oxidative coupling of methane system to convert methane to ethylene, followed by conversion of ethylene to selectable higher hydrocarbon products. Integrated systems and processes are provided that process methane through to these higher hydrocarbon products.
Abstract:
Es wird ein Verfahren zur kombinierten Erzeugung von mechanischer Leistung und Herstellung von Reaktionsprodukten vorgeschlagen, bei dem zur Erzeugung der mechanischen Leistung wenigstens eine Verbrennungskraftmaschine (1) unter Erhalt eines Verbrennungsabgases (c) befeuert und zur Herstellung der Kohlenwasserstoffe wenigstens ein Reaktor (2) unter Verwendung eines Brennstoffs (e) und eines Verbrennungsunterstützungsgases (d) beheizt wird. Es ist dabei vorgesehen, dass zumindest ein Teil des Verbrennungsunterstützungsgases (d) durch indirekten Wärmetausch mit zumindest einem Teil des Verbrennungsabgases (c) der Verbrennungskraftmaschine (1) erwärmt wird. Eine entsprechende Anlage (100, 200) ist ebenfalls Gegenstand der vorliegenden Erfindung.
Abstract:
The invention relates to mixtures comprising molecular hydrogen, hydrocarbons, and nitrogen oxides; to processes for removing at least a portion of the nitrogen oxides therefrom; to equipment useful in such processes; and to the use of such hydrocarbons for, e.g., chemical manufacturing.
Abstract:
Processes are provided for the production of butadiene from C 4 containing feed stocks that contain isobutene and/or isobutane in addition to n-butcne(s) and/or n-butane. The processes of the present invention generally comprise feeding the feed stock to a combination butenes isomerization reaction and distillation tower for conversion of I -butene to 2-butenes and separation from isobutene and isobutane, followed by an oxydchydrogenation unit to convert n-butenes to butadiene. The processes may also include additional isomerization and/or dehydrogenation steps for the tower overhead and bottoms streams to create additional isobutene and/or n-bulenes for valued uses, which may include additional production of butadiene. The feed to the system may comprise any mixture or separate feeding of C 4 olefins and C 4 paraffins, at least one of which contains isobutene and/or isobutane.
Abstract:
The present invention relates to a process for obtaining a highly soluble linear alkylbenzene sulfonate with an adjustable 2-phenyl isomer content and an extremely low sulfonation color, in which a catalytic system based on highly stable solid catalysts and with a high selectivity for linear monoalkylated compounds is used.
Abstract:
The invention concerns a method for dehydrogenating C2-C30 alkanes, which consist in: (i) in a first process, dehydrogenating ethyl benzene into styrene, generating a hydrogen-containing gas stream, and (ii) in a second process, dehydrogenating one or several C2-C30 alkanes heterogeneously catalyzed in one or several reaction zones into corresponding olefins, a hydrogen-containing gas stream being mixed in at least one reaction zone with the dehydrogenation reaction gas stream. The invention is characterized in that at least part of the hydrogen-containing gaseous effluents derived from ethyl benzene dehydrogenation is added to the alkane dehydrogenation reaction gas mixture.
