9.3 Appendix 3— Summary of Attached Papers Y. Chen, P. Lundqvist, P. Platell, “Theoretical Research of Carbon Dioxide Power Cycle Application in Automobile Industry to Reduce Vehicle’s Fuel Consumption”, Applied Thermal Engineering 25 (2005), pp 2041–2053 This work discusses means to utilize low‐grade energy in vehicle exhaust gases, to reduce the vehicle’s fuel consumption and to make it run in a more environmentally friendly way. To utilize the energy in the exhaust gas, a CO2 bottoming system in the vehicle’s engine is proposed. Several basic cycles— according to the different design concepts—are presented, and the efficiencies are calculated using Engineering Equation Solver (EES). Several thermodynamic models in EES show that after system optimization, in a CO2 transcritical power cycle with a gas heater pressure of 130 bar and 200°C expansion inlet temperature, about 20% of the energy in the exhaust gas can be converted into useful work. Increasing the pressure in the gas heater to 300 bar and with the same expansion inlet temperature, about 12% of the exhaust gas energy can be converted. When the pressure is raised both in the gas cooler and in the gas heater, the cycle runs completely above the critical point, and the efficiency is about 19%. In addition, in the CO2 combined cycle, the system COP is 2.32 and about 5% of the exhaust gas energy can be converted. Y. Chen, P. Lundqvist, A. Johansson, P.

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
