Systematic adsorption experiments were carried out to elucidate the effects of different process parameters such as adsorbent dose, initial fluoride concentration, pH of the solution and effect of other ions (usually present in groundwater). These studies were aimed to understand the adsorption behaviour of the PURAL (R) MG-20 adsorbents. Fluoride adsorption by PURAL (R) MG-20 sorbent was found pH dependent. Maximum fluoride removal efficiency was observed in the range of pH 5-7. Langmuir isotherm described the data better than Freundlich and Temkin isotherm models and the adsorption capacity was found to be 5.62 mg g(-1) at initial fluoride concentration of 5.13 mg L-1, pH 7 and contact time 24 h. The kinetic result shows that the fluoride sorption follows pseudo-second-order kinetics. Column breakthrough studies were performed to test the performance of the adsorbent media at continuous mode of operation. Thus, it can be concluded that PURAL (R) MG-20 adsorbent can be used directly for field applications since it shows high fluoride uptake capacity under simulated drinking water conditions and it is also commercially available.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">9</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">1.685

Understanding into the effect of operational parameters like type of solvent, extraction temperature, solid to solvent ratio and raw material size distribution as well as the equipment operating conditions as frequency and power on the extraction yield has been developed. Based on the results for extraction yield, the optimum conditions for UAE approach were 40 degrees C as temperature, 1:30 as solid to solvent ratio, 0.09 mm as the mean particle size, 240 W as ultrasonic power, 22 kHz as ultrasonic frequency and ethanol as the most suitable solvent. Under these optimum conditions, the highest extraction yield of 73.18% was achieved in 2 h whereas batch extraction for 14 h resulted in 52.31% yield clearly demonstrating the intensification due to ultrasound. Peleg's model was applied to explain the extraction kinetics of curcumin and the proposed model satisfactorily predicted the rates of extraction of cur cumin. Overall, UAE proved to be a better technique in terms of lesser time, lesser heating requirement and additional extraction yield.</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">4.237</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bagwan, Farahanaz M.</style></author><author><style face="normal" font="default" size="100%">Dongapure, Pavan</style></author><author><style face="normal" font="default" size="100%">Kulkarni, Amol A.</style></author><author><style face="normal" font="default" size="100%">Vasireddy, Satyam Naidu</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Experimental and kinetic modelling studies for the design of fixed bed methanol reactor over CuZA catalyst</style></title><secondary-title><style face="normal" font="default" size="100%">Chemical Engineering Research Design </style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">CO2 conversion</style></keyword><keyword><style  face="normal" font="default" size="100%">CuZA catalyst</style></keyword><keyword><style  face="normal" font="default" size="100%">H2 toCO2 molar ratio</style></keyword><keyword><style  face="normal" font="default" size="100%">Kinetic modelling</style></keyword><keyword><style  face="normal" font="default" size="100%">Methanol</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2024</style></year><pub-dates><date><style  face="normal" font="default" size="100%">MAY</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">205</style></volume><pages><style face="normal" font="default" size="100%">79-90</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;
	Direct conversion of CO 2 via hydrogenation to value-added chemicals is a vital approach for utilising CO 2 emitted into the atmosphere. In this paper, a critical analysis of reaction kinetic modelling studies is explored in a fixed bed reactor to improve methanol yield for different H 2 to CO 2 ratios by simulating a lab-scale reactor for adiabatic and isothermal conditions. The feed inlet temperature and pressure variations are applied to study the effect of both configurations on methanol production. The results show that the isothermal configuration yields 2.76% more methanol yield compared to the adiabatic reactor. The effect of H 2 to CO 2 molar ratios of 3, 6 and 9 on the performance of the catalyst and the influence of CO and CO 2 hydrogenation is investigated with model simulations. The overall methanol yield is increased from 19.03% to 36.41% with increase in H 2 to CO 2 molar ratio from 3 to 9. Experiments are performed using commercial copper-based catalyst for different temperatures of 210, 230 and 250 degrees C at a pressure of 40 bar for H 2 /CO 2 of 3 and GHSV of 720 h -1 as well as at optimal temperature of 250 degrees C and 50 bar with varying H 2 /CO 2 of 3, 6, 9 for 3 g and 6 g catalyst. The maximum methanol yield of 2.53% and space time yield of 13.59 mg/g cat .h is obtained at H 2 /CO 2 ratio of 9.&lt;/p&gt;

	The polycation-exchanged ETS-10 (Li-K-ETS-10) zeolite was employed as a sorbent in breakthrough experiments using a binary H2/CO2 (75/25%) gas mixture. The data compared with parent adsorbent (NaK)-ETS-10, and mono cation exchange of ETS-10 (K-ETS-10 and Li-ETS-10). Adsorbents underwent for various characterization including XRD, Raman, FTIR, EDS, CO2-TPD, BET surface area, and pore diameter of samples to understand the physicochemical properties. CO2-TPD shows that Li-K-ETS-10 has higher basicity than parent (NaK)-ETS-10. The process parameters were optimized to ensure a higher CO2 sorption capacity and better H2 purity including effects of flow rate, pressure, temperature, feed concentration, bed height, and recyclability. The adsorption capacities of CO2 and H2 were found to be 1.57 mmol g- 1 and 0.24 mmol g-1, respectively, at 1 bar and a flow rate of 200 mL min- 1. These values represent a 40% improvement over (NaK)-ETS-10 and a-10.4% improvement over Li-ETS-10. At 6 bar, the CO2 and H2 adsorption capacities reached 2.79 mmol g- 1 and 0.22 mmol g-1, respectively. The higher CO2 sorption over Li-K-ETS-10 leads due to improve in basic sites and physical properties of sample compare to studied adsorbent. The experimental data of binary gas mixture was used to evaluate the kinetic models including Thomas, and Yoon-Nelson. This results implies that Li-K-ETS-10 is the promising candidates for H2 separation from binary gas mixture.&lt;/p&gt;
