Hydrogen-assisted adsorption of sulphur compounds from olefin mixtures

The invention relates to a process for purifying hydrocarbon mixtures, in which a contaminated hydrocarbon mixture comprising olefins having three to eight carbon atoms is at least partly freed of sulphur-containing contaminants by contacting it with a solid sorbent, the hydrocarbon mixture being exclusively in the liquid state during the contact with the sorbent. The problem that it addressed was that of virtually completely removing sulphur compounds present in the mixture without forming new sulphur compounds again at the same time. At the same time, 1-butene present therein was not to be lost in the purification of the mixture. Finally, the sorbent used was to have a high sorption capacity, be very substantially free of carcinogenic constituents and be readily available. This problem is solved by using a sorbent based on copper oxide, zinc oxide and aluminium oxide in a particular composition, and by conducting the purification in the presence of a small amount of hydrogen.

Combined preparation of butene and octene from ethene

The heterogeneously catalysed, combined preparation of butene and octene from ethene comprises simultaneously carrying out two reactions, namely a first reaction of C2 to form C4 and a second reaction of C2 and C6 to form C8. The two reactions are carried out physically separately from one another and in the presence of an inert solvent whose boiling point is between that of the butenes and that of the octenes. The hexene formed as by- product in the first synthesis is used as starting material for the second synthesis. There, it is reacted with ethene to form octene. The solvent is continually circulated. This makes it possible to carry out both syntheses in the liquid phase and to control their selectivity. Since the boiling point of the solvent corresponds essentially to that of the by-product hexene, the by-product can be separated off together with the solvent as intermediate boiler from the first reaction mixture and transferred to the second reaction.

Vehicular headlight providing high-beam and depressed-beam illumination, and light source therefor

To provide for improved light distribution of a vehicular headlight furnishing both depressed-beam and high-beam illumination, a shadow cap (9, 25) partly surrounds a main light source located in a reflector (2) which has two segments ( 14, 15 ) of different contours. The first one (14) of the reflector segments is optically associated with the main light source furnishing depressed-beam illumination, and this segment has a free-formed surface reflection contour. A second segment of the reflector is optically associated with an auxiliary light source (8, 18) which is shaded by a shadow cap. The shadow cap (9, 25 ) provides a shadow angle of between 100° and 140° with respect to light emitted from the main light source (7) to define a shadow zone (12) and a light zone (13) on the reflector. The shadow cap is shaped and positioned with respect to the auxiliary light source such that the auxiliary light source is located within the shadow zone (12). The auxiliary light source is located by an offset of between 0.25 and 2 tunes below the optical axis (A) of the reflector, and the spatial distribution of the segments is such that the reflector is associated with a light zone and a shadow zone, respectively, as formed by the shadow cap. For high-beam illumination, both the auxiliary light source and the main light source, typically filaments of a halogen incandescent lamp, are energized, so that the respective illuminations are superposed, providing spread-out illumination from the main light source (7) and somewhat diffused spread illumination as well as a concentrated beam from the auxiliary light source (8, 18).

Process for the flexible preparation of aldehydes

Der Erfindung liegt die Aufgabe zu Grunde ein Verfahren anzugeben, mit welchem sich sowohl C 5 - als auch C 9 -Aldehyde wirtschaftlich produzieren lassen. Dabei soll das Verfahren mit möglichst geringer Abhängigkeit von Rohstofflieferanten versorgt werden können und zudem flexibel auf Nachfrageschwankungen hinsichtlich C 5 - und C 9 - Aldehyde reagieren können. Außerdem ist der Ressourceneinsatz zu optimieren. Das vorgeschlagene Verfahren nutzt LPG bzw. NGL als Rohstoff. Von bekannten, LPG basierten Verfahren unterscheidet sich das erfindungsgemäße Verfahren im Wesentlichen dadurch, dass das nach Dehydrierung und Abtrennung der Nebenprodukte erhaltene Intermediat in zwei Portionen aufgeteilt wird. Aus der ersten Portion wird über Oligomerisierung und Hydroformylierung C9-Aldehyd hergestellt, währenddessen der C 5 -Aldehyd durch Hydroformylierung der zweiten Portion erhalten wird. Dies hat den entscheidenden Vorteil, dass das Intermediat flexibel in die beiden Portionen aufgeteilt werden kann, sodass wahlweise mehr C 5 oder mehr C 9 - Aldehyde herstellbar sind, abhängig von der jeweiligen Nachfrage.

In addition, the use of resources must be optimized. The proposed method uses LPG or NGL as raw material. The process according to the invention differs from known, LPG-based processes essentially in that the intermediate obtained after dehydrogenation and separation of the by-products is divided into two portions. From the first portion, C9 aldehyde is prepared via oligomerization and hydroformylation, while the C5 aldehyde is obtained by hydroformylation of the second portion. This has the decisive advantage that the intermediate can be flexibly divided into ...

Ethylene oligomerisation under supercritical conditions

Die Erfindung befasst sich mit der Oligomerisierung von überkritischem Ethen. Ein Wesentlicher Aspekt der Erfindung ist, dass Ethen mit einem Inertmedium zu vermischen und die Bedingungen bei der Reaktion so einzustellen, dass sowohl Ethen als auch Inertmedium überkritisch sind. Im überkritischen Zustand ist nämlich die Löslichkeit für Ethen in dem Inertmedium größer, sodass mehr Ethen in dem überkritischen Inertmedium gelöst werden als in einem flüssigen Lösemittel. Die Prozessführung im überkritischen Zustand ermöglicht es daher, einen deutlich höheren Anteil Ethen in einer homogenen Mischung aus Ethen und Inertmedium einzusetzen, als es aufgrund der thermodynamischen Löslichkeitsbeschränkung in einem rein flüssigen Kohlenwasserstoffstrom möglich ist. Auf diese Weise wird die Raum-Zeit-Ausbeute deutlich gesteigert. Da eine größere Menge Ethen in den Reaktor geleitet werden kann, lässt sich im Ergebnis das Apparatevolumen verglichen mit einem Flüssigphasen-Verfahren besser auszunutzen. Als Inertmedium kann beispielsweise Isobutan verwendet werden. The invention is concerned with the oligomerization of supercritical ethene. An essential aspect of the invention is that of mixing ethene with an inert medium and adjusting the conditions in the reaction so that both ethene and inert medium are supercritical. Namely, in the supercritical state, the solubility for ethene in the inert medium is larger, so that more ethene is dissolved in the supercritical inert medium than in a liquid solvent. Process control in the supercritical state therefore makes it possible to use a significantly higher proportion of ethene in a homogeneous mixture of ethene and inert medium than is possible due to the thermodynamic solubility limitation in a purely liquid hydrocarbon stream. In this way, the space-time yield is significantly increased. As a result, since a larger amount of ethene can be fed into the reactor, the apparatus volume can be better utilized as compared with a liquid phase ...

Oligomerization of ethene in supercritical mode

The invention is concerned with the oligomerization of supercritical ethene. An essential aspect of the invention is that of mixing ethene with an inert medium and setting the conditions in the reaction such that both ethene and inert medium are supercritical. This is because the solubility for ethene in the inert medium is greater in the supercritical state, such that more ethene is dissolved in the supercritical inert medium than in a liquid solvent. The process regime in the supercritical state therefore enables the use of a much higher proportion of ethene in a homogeneous mixture of ethene and inert medium than is possible on the basis of the thermodynamic solubility restriction in a purely liquid hydrocarbon stream. In this way, the space-time yield is distinctly enhanced. Since a greater amount of ethene can be passed into the reactor, it is possible as a result to better exploit the apparatus volume compared to a liquid phase process. The inert medium used may, for example, be isobutane.
