Coiled and twisted nanofiber yarns for electrochemically harvesting electrical energy from mechanical deformation
Yarn energy harvesters containing conducing nanomaterials (such as carbon nanotube (CNT) yarn harvesters) that electrochemically convert tensile or torsional mechanical energy into electrical energy. Stretched coiled yarns can generate 250 W/kg of peak electrical power when cycled up to 24 Hz, and can generate up to 41.2 J/kg of electrical energy per mechanical cycle. Unlike for other harvesters, torsional rotation produces both tensile and torsional energy harvesting and no bias voltage is required, even when electrochemically operating in salt water. Since homochiral and heterochiral coiled harvester yarns provide oppositely directed potential changes when stretched, both contribute to output power in a dual-electrode yarn. These energy harvesters were used in the ocean to harvest wave energy, combined with thermally-driven artificial muscles to convert temperature fluctuations to electrical energy, sewn into textiles for use as self-powered respiration sensors, and used to power a light emitting diode and to charge a storage capacitor. |

Maximizing octane savings in a catalytic distillation unit via a dual reactor polishing system
Low sulfur gasoline blend stock is produced by a hydrodesulfurization process including at least two hydrodesulfurization reactors with hydrogen feeds and two finishing reactors arranged where the first polishing reactor converts both thiophenic compounds and mercaptans to hydrogen sulfide and hydrocarbons and the second polishing reactor uses a catalyst that has much less thiophenic conversion activity but is operated at a higher temperature to more substantially reduce the sulfur content of the gasoline present in the form of mercaptans. As the conversion of thiophenes to hydrogen sulfide is correlated to reducing octane number, using a second polishing reactor that has little activity for thiophene conversion also protects the high-octane species in the gasoline thereby minimizing octane loss while reducing total sulfur content to acceptable levels. The sulfur left in the gasoline is biased toward higher thiophene content and away from mercaptan content. |
