Table 11: Main requirements for adsorbent-adsorbate pairs. Adsorbate Adsorbent • high latent heat • non-corrosive • non-toxicity • thermal stability • chemical stability • High adsorption capacity • high thermal conductivity • low cost • thermal stability Table 12: Thermo-physical properties of adsorbents (Srivastava and Eames, 1998) Adsorbent Adsorbate Heat of adsorption, Remarks kJ/kg Activated alumina H2O 3000 Silica gel CH3OH H2O 1000-1500 2800 Not suitable for above 200oC Cooling Zeolite (various grades) H2O NH3 CO2 CH3OH 3300-4200 4000-6000 800-1000 2300-2600 Natural zeolites have lower values than synthetic zeolites Charcoal C2H4 NH3 H2O CH3OH C2H5OH 1000-1200 2000-2700 2300-2600 1800-2000 1200-1400 Reacts at about 100oC Zeolite–water, active carbon–methanol, silica gel—water, and carbon–ammonia are some of the common adsorbent–adsorbate pairs used in adsorption heat pump systems (Srivastava and Eames, 1998; Cerkvenik et al, 2001; Wang et al, 2005-c). 4.3.2 Metal hydride storage Metal hydride heating and cooling systems operate similar to conventional solid sorption systems, employing, for example, activated carbon/ammonia, silica gel/water, as working pairs. The potentially most useful complex metal hydrides are aluminium hydride and composite metal hydrides. Na(AlH4) and Na(BH4) are reported as promising alternatives especially as hydrogen storage materials for mobile applications such as for use in fuel cells. Their use for thermodynamic devices has, however, not been considered so far (Muthukumar and Groll, 2010). 39PDF Image | EPSRC Thermal Management of Industrial Processes

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
