133 RESULTS AND DISCUSSION 134 Optimizing the reaction temperature 135 Figure 2 shows the XRD patterns of the LDH sorbents with nominal Li:Al = 1:3 synthesized at 136 various temperatures. Almost all peaks in each pattern can be indexed with a hexagonal 137 P63/mcm model. The data indicates a nearly single phase of layered LDH with a very small 138 amount of unreacted gibbsite -Al(OH)3. Furthermore, sharper peaks can be clearly observed for 139 the 90 C sample compared to those for samples synthesized at lower temperatures, which 140 indicate that the 90 C sorbent is of best crystallinity. This can be readily explained, from the 141 previous study of time-resolved in-situ X-ray diffraction experiments involving LiCl and 142 gibbsite.16 The temperature dependence of the intercalation reaction data of LiCl and Gibbsite 143 was fitted into Avrami-Erofe’s ev equation. By assuming Avrami-Erofe’ev kinetics, a two 144 dimensional diffusion-controlled growth model following instantaneous nucleation was 145 proposed. Hence, Avrami-Erofe’ev equation becomes 146 147 α = 1 - exp(-kt) (1) 148 149 The validity of this equation for the whole process was confirmed by a Sharp-Hancock analysis 150 and the plot of ln k versus 1/T yielded Ea, activation energy of 27 kJ mol-1.16 This value is in 151 agreement with the activation energy for lithium intercalation in TiS2 giving Li0.2TiS2. Hence, a 152 highly crystalline sample is expected to be superior in that the well-defined layered structure 153 would allow for more efficient insertion/extraction of the LiCl ions. 7PDF Image | Recovery of Lithium from Geothermal Brine Li AL

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
