Coatings 2021, 11, 854 3 of 13 production of Basolite A520 material, which proved the difficulty to manufacture MOF material with hydrothermal method in [40]. In this article, a novel method to generate MIL-121 was investigated. The developed method can be used to produce MOF material at ambient pressure and temperature below 100 ◦C. The MIL-121 obtained by the novel method has the same lithium adsorption performance as that obtained by hydrothermal method, but with lower energy consumption and is more environmentally friendly. Compared to hydrothermal method, this method is more potential to be industrialized. 2. Materials and Methods 2.1. Material and Device The parallel crystallizer (EasyMax 402 Basic, METTLER TOLEDO Group, Shanghai, China) produced by METTLER TOLEDO Group and the constant-speed program tempera- ture controlled by a thermostat produced by Nanjing Xianou Instrument Co., Ltd. were used to control the cooling and crystallization process. The crystal products obtained in the experiments were observed by the field emission high-resolution scanning electron mi- croscope SEM (FEI, Apreo, Japan). The powder X-ray diffractometer (Shimadzu XRD-6100, Shimadzu, Japan) and Fourier infrared spectrometer FTIR (BRUKER TENSOR 27, Bruker, Germany) provided by the Analysis Center of the School of Chemical Engineering and Materials were used for qualitative analysis of the products. The TG (Netzsch, Germany) was implemented to analyze the thermal stability of the crystal material in the temperature range of 50~800 ◦C under the protection of N2 atmosphere. The LabRAM HR800 micro- probe Raman system was used to analyze the Raman peak of the product. The particle size distribution of the crystals is also analyzed by the BECKMANCOULTER LS series laser particle size analyzer. In order to confirm the crystal form and polymorphic purity of the products, powder X-ray diffraction (PXRD) patterns were recorded on a Shimadzu PXRD-6100 diffractometer equipped with Cu Kα source at a scanning rate of 5◦ min−1. The crystal habit of MIL- 121 was determined by scanning electron microscope SEM (FEI, Apreo, Japan). The size of the crystals was characterized using a laser diffraction particle size analysis meter (Beckman Coulter LS, Beckman, CA, America) at a pump speed of 52 r/min and ultrasonic time 5 s. The Fourier transform-infrared (FT-IR) spectra (potassium bromide pellets) were obtained on a TENSOR27 (Bruker, Germany) FT-IR spectrometer instrument in the wavenumber range of 400–4000 cm−1. The Raman detection was carried out on a LabRAM HR800 microprobe Raman system (Horiba Jobin-Yvon, France) with excitation of 532 nm. The Raman band of a silicon wafer at 520 cm−1 was used as a reference to calibrate the spectrometer. The Raman shift range is 250–4000 cm−1 and the exposure time is 5 s. The thermogravimetric data were collected by SDT-Q600 differential of American TA Company performed in the temperature range of 40–50 ◦C, with a temperature scanning rate of 20 ◦C min−1 in 50 mL min−1 N2 gas flow. 2.2. Investigation of the Crystallization Process A parallel crystallizer (EasyMax 402 Basic) was used to investigate the cooling crys- tallization process. Al(NO3)3·9H2O 2.4 g, H4BTEC(pyromellitic acid) 0.8 g, and 10 mL deionized water were added to six identical 20 mL capped test tubes. The experiment adopts different holding time (3, 5, 10 h) and cooling method (cooling rate 0.3 ◦C/min and rapid cooling method). The reaction temperature was 80 and 100 ◦C, respectively. When the reaction temperature is 80 ◦C, as the reaction time increases, the output of MIL- 121 also increases. The reaction temperature is 3 h, the product of MIL-121 is 0.083 g, the reaction temperature is 5 h, the product of MIL-121 is 0.231 g, the reaction temperature is 10 h, and the product of MIL-121 is 0.486 g. The effects of holding time, cooling method, and reaction temperature on the grain size and yield of MIL-121 were investigated.PDF Image | Small Particles for Lithium Adsorption from Brine

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)
