Abstract: A process for producing olefins from oxygenates includes the following steps: (i) heterogeneously catalyzed conversion of at least one oxygenate to a stream containing propylene, aromatics and cyclic olefins, (ii) at least partial hydrogenation of the aromatics and cyclic olefins to naphthenes, and (iii) at least partial recirculation of the naphthenes into the heterogeneously catalyzed conversion.

Abstract: A process for producing olefins from oxygenates comprises the following steps: (i) heterogeneously catalyzed conversion of at least one oxygenate to an entire stream containing propylene, aromatics and cyclic olefins; (ii) olefin interconversion of at least a part of the entire stream; (iii) separation of a stream rich in aromatics from the reaction product of the olefin interconversion; and (iv) hydrogenation of the stream rich in aromatics.

The enclosed track receives and permits sliding of at least one of the first and second members.

Abstract: A process for producing short-chain olefins by conversion of oxygenates in a multi-stage fixed-bed reactor, in which the individual stages for reaction zones are covered with beds of a granular, form-selective zeolite catalyst and the feed mixture containing oxygenates is added distributed over the reaction stages. An increase of the availability of the fixed-bed reactor for the olefin production with the same or an increased yield of short-chain olefins is achieved in that one or more reaction zones are charged with a distinctly reduced mass flow of the feed mixture containing oxygenates, wherein the reduced mass flow fraction is distributed over other reaction zones.

Abstract: A process and a plant for producing an olefin stream from a hydrocarbon mixture feed stream, wherein the olefin stream is depleted as regards its content of oxygen-containing organic compounds (oxygenates) as compared to the feed stream. The hydrocarbon mixture feed stream is charged to a separation column operated by a thermal separation process, for example to a distillation column, wherein a material stream enriched in oxygenates is withdrawn via a side outlet and removed from the process. The process according to the invention is particularly useful for processing the product streams obtained in the olefin synthesis by an OTO process.

Abstract: A dispensing system has a central longitudinal axis and includes a shroud adapted to receive a container. The shroud includes a gripping portion adapted to be gripped by a hand of a user. The dispensing system also includes an actuation member adapted to rotate about a rotation point on a rotation axis toward an interior of the shroud in response to a force applied to the actuation member by the user. The actuation member is configured such that a rotation distance is at least about 6 centimeters. The rotation distance is measured in a direction parallel to the central longitudinal axis between a location where the user can apply the force to the actuation member and the rotation point of the actuation member.

Abstract: Mechanical inversion of direction of a rotating control component of a landscape sprinkler device. Such a device, having a switching member with end stops associated therewith in both pivoting directions the control component, against said stops the switching member stops and is actuated, wherein at least one end stop can be adjusted coaxially with respect to a pivoting axis of the control component. The switching member is configured in an elastically resilient manner on the contact region thereof that is positioned at the height of the end stops such that the contact region retreats back from the adjusting path of the end stop in case of an overload, and devices are provided in order to re-establish the contact region at a defined position in the rotation angle region between the two end slops from the retreated position.

Abstract: A thermoplastic bottle has a crimped valve cup and a method of manufacturing a thermoplastic bottle includes crimping a valve cup to such a bottle. The thermoplastic bottle and valve cup may be used in a system to dispense aerosol products. At least one protrusion extends from a flange of the bottle to which the valve cup is crimped. Prior to being crimped to the bottle, the valve cup is set to the bottle with an interference fit between a crimping portion of the valve cup and the protrusion. The interference fit prevents shifting of the valve cup from its set position on the bottle prior before the valve cup is crimped.
