Supported Nonmetallocene Olefin Polymerization Catalyst, Preparation Method and Use Thereof

The present invention provides a method for supporting a nonmetallocene olefin polymerization catalyst, comprising the following steps: a carrier reacts with a chemical activator to obtain a modified carrier; a magnesium compound is dissolved in a tetrahydrofuran-alcohol mixed solvent to form a solution, then the modified carrier is added to the solution to perform a reaction, then filtered and washed, dried and suction dried to prepare a composite carrier; a nonmetallocene olefin polymerization catalyst is dissolved in a solvent, and then reacts with said composite carrier, then is washed and filtered, dried and suction dried, to prepare a supported nonmetallocene olefin polymerization catalyst. The present invention further relates to a supported nonmetallocene olefin polymerization catalyst as prepared by this method. The present invention further relates to the use of the supported nonmetallocene olefin polymerization catalyst in an olefin polymerization and an olefin copolymerization between two or more different olefins. In one specific embodiment, the present invention relates to the use of the supported nonmetallocene olefin polymerization catalyst in a slurry ethylene polymerization. The present invention provides a new type of catalyst that improves the polymer morphology, increases polymer bulk density and enhances polymerization activity.

Multi-Channel Time Slice Groups

ActiveUS20130152093A1Increase overall throughput and performanceIncurring costMemory systemsProgram saving/restoringContextual informationParallel processing
A time slice group (TSG) is a grouping of different streams of work (referred to herein as “channels”) that share the same context information. The set of channels belonging to a TSG are processed in a pre-determined order. However, when a channel stalls while processing, the next channel with independent work can be switched to fully load the parallel processing unit. Importantly, because each channel in the TSG shares the same context information, a context switch operation is not needed when the processing of a particular channel in the TSG stops and the processing of a next channel in the TSG begins. Therefore, multiple independent streams of work are allowed to run concurrently within a single context increasing utilization of parallel processing units.

Process for the desulphurization of feed streams

The invention relates to: a process for the desulphurization of feed streams comprising: supplying a hot process stream to a lead catalyst bed (8) comprising a first sulphur-removing catalyst and a second sulphur-removing catalyst under conditions whereby sulphur is removed from the process stream by the first sulphur-removing catalyst and said second sulphur-removing catalyst does not effectively remove sulphur from the stream at the operating temperature of the lead catalyst bed for the duration of the bed's life; collecting a hot partially sulphur-depleted stream from the lead catalyst bed and cooling said stream; passing said cooled stream through a lag catalyst bed (11) comprising the first sulphur-removing catalyst and the second sulphur-removing catalyst under conditions whereby sulphur is removed from the process stream by the second sulphur-removing catalyst and said first sulphur-removing catalyst removes sulphur less efficiently from the stream at the operating temperature of the lag catalyst bed; and recovering said sulphur-depleted stream from the second catalyst bed. In addition it relates to, apparatus for the desulphurization of feed streams which comprises: a lead catalyst bed (8) comprising a first sulphur-removing catalyst and a second sulphur-removing catalyst capable of operating under conditions whereby sulphur is removed from the process stream by the first sulphur-removing catalyst and said second sulphur-removing catalyst does not effectively remove sulphur from the stream at the operating temperature of the lead catalyst bed (8) throughout the lead bed's operating life; means (9) for collecting a hot partially sulphur-depleted stream from the lead catalyst bed (8) and cooling said stream; a lag catalyst bed (11) comprising the first sulphur-removing catalyst and the second sulphur-removing catalyst capable of operating under conditions whereby sulphur is removed from the process stream by the second sulphur-removing catalyst and said first sulphur-removing catalyst does not efficiently remove sulphur from the stream at the operating temperature of the lag catalyst bed(11).

Systems and methods for fuel level estimation

Methods and systems are provided for estimating fuel levels in a fuel tank. In one example, a method may comprise adjusting estimates of a fuel level in a fuel tank based on an amount of fuel added to the fuel tank during a refueling event. The amount of fuel added to the fuel tank may be provided by a vehicle operator via one or more of a dashboard user interface, a wireless device user interface, and a digital camera included within a user device.

Backup battery charger

A backup battery charger charges a backup battery of a handheld electronic device. The handheld electronic device comprises a power supply unit and an electronic component. The power supply unit supplies a power to the electronic component. The backup battery charger is connected to the electronic component, such that the backup battery charger shares with the electronic component the power, uses the power as a charging power, and controllably determines via a control module whether to supply the charging power to the backup battery.

Vertical bipolar transistor formed using CMOS processes

A vertical bipolar transistor is described which utilizes ion implantation steps which are used to form an nMOS field effect device and a pMOS field effect device. The implantation steps form an n-well, a channel stop p-well region and emitter region which are vertically oriented within a semiconductor substrate. The resulting bipolar device is junction isolated from other circuits formed on the substrate by a p-well region.
