摘要:
A process for the preparation of heterogeneous zirconium based catalyst for polymerization of alpha-olefins to super high molecular weight poly (alpha-olefins). The process comprises in mixing zirconium alcholate or phenolate with anhydrous magnesium chloride in the presence of a solvent. The mixture is heated, then cooled and an organoaluminum compound is added. Optionally, an electron donor compound is added and heated to obtain a black slurry, which is cooled and then washed with a hydrocarbon diluent.
摘要:
Disclosed herein is a single pot process for producing biodiesel and the product thereof, using non-edible oil sources containing free fatty acid. The process comprises esterification and transesterification of non-edible vegetable oil sources containing free fatty acids in a single pot employing a water scavenger or a water adsorbent or a mixture thereof.
摘要:
In a preferred embodiment, the present invention is a system for avoiding voltage emergencies. The system comprises a microprocessor, an actuator for throttling the microprocessor, a voltage emergency detector and a voltage emergency predictor. The voltage emergency detector may comprise, for example, a checkpoint recovery mechanism or a sensor. The voltage emergency predictor of a preferred embodiment comprises means for tracking control flow instructions and microarchitectural events, means for storing voltage emergency signatures that cause voltage emergencies, means for comparing current control flow and microarchitectural events with stored voltage emergency signatures to predict voltage emergencies, and means for actuating said actuator to throttle said microprocessor to avoid predicted voltage emergencies.
