Summary: This study reveals, for the first time, the technological valorization of abundant Amazon Brazilian kaolin mining waste to synthesize pure-phase zeolitic material with antibacterial application. By optimizing the synthesis conditions, crystalline Linde Type A (LTA) zeolite can be obtained using thermally treated or natural kaolin, with a rapid crystallization process of 6 hours without the need for commercial aluminum supplementation. The resulting zeolite materials, exchanged with zinc ions, exhibit antibacterial activity against both Gram-positive and Gram-negative bacteria, offering new opportunities for the management of waste in the kaolin mining industry.

Summary: The study successfully validated a model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) using a LTA zeolite hydrophilic membrane. Experimental runs showed that the model accurately predicted the molar fractions of compounds in the reaction medium and their evolution over time. The partial separation of H2O from the reaction medium in the PBMR led to higher DME yield, CO and CO2 conversions compared to systems without membrane.

Summary: The pilot plant extrusion was successfully used to convert clay-based solid waste from spent oil refinery landfill into rod-like zeolite with LTA structure. The addition of boehmite and sodium hydroxide compensated for the lack of aluminum in the waste. Proper aging and reaction periods resulted in a packed bed with suitable cation exchange capacity. Although the textural characteristics of zeolites were slightly affected by extrusion, the innovative technique showed potential in producing zeolite rods with proper CEC.

Summary: Changing synthetic parameters such as TMAOH/NaOH ratio, aging time, and hydrothermal conditions significantly influences the crystal size and uniformity of LTA zeolites. By adjusting the TMAOH/NaOH ratio, the average crystal size of LTA zeolite crystals can be tuned from less than 100 nm to 1 μm with a uniform distribution. Increasing aging time results in smaller and more uniform LTA zeolite crystals.

Summary: Air-gap membrane distillation (AGMD) is a novel method that can reduce heat requirements for water purification. However, AGMD faces challenges such as low water permeate flux and downstream performance reduction. A 2D comprehensive study using computational fluid dynamics (CFD) simulation was conducted to examine the effectiveness of solar absorbers and spacer filaments in addressing these challenges. The results demonstrated that solar absorbers slightly increased water flux and decreased temperature and concentration polarisation effects, while cylindrical detached spacers improved water flux compared to other types of spacers. The proposed spacer-filled module significantly enhanced AGMD performance and resulted in uniform water flux throughout the module.

Summary: This study examined the impact of solar absorbers and different spacer filaments on the performance of direct contact membrane distillation (DCMD). A computational fluid dynamics model was developed to simulate water flux in DCMD modules with different designs of solar absorbers and spacer filaments. The results showed that a module equipped with a solar absorber membrane enhanced the DCMD performance better than a module with a solar absorber plate. Moreover, a module with cylindrical detached spacer filaments improved DCMD performance more than a module with rectangular and semicircular attached spacers. Finally, a module equipped with an integrated developed spacer and solar absorber membrane significantly enhanced water flux and both concentration and temperature polarisations, particularly when the inlet velocity was increased.

Summary: This study evaluated the potential benefits of thermally integrating a membrane distillation heat exchanger (MDHX) with water electrolysis for thermal management of waste heat and simultaneous production of fresh water for hydrogen production. A MATLAB model was used to simulate a combined MDHX and water electrolysis stack, showing that the MDHX-EC system can regulate the temperature of an AEM electrolyser and produce fresh water at the same rate as water consumption. These results suggest that further experimental studies should be conducted to explore the performance and economic benefits of this integrated system.

Summary: This paper reviews non-thermal methods for concentrating juices, mainly focusing on the developments of forward osmosis (FO) membranes for juice processing, detailing the benefits and limitations of this technology. A laboratory FO membrane was used in this preliminary study to concentrate pure sucrose solutions and clarified juice using a calcium chloride draw solution. The study found that the non-sucrose substances in factory juices had little impact on flux performance, and by concentrating to a limit of 45% rds, detrimental concentration polarisation factors were not observed. Possible strategies were also explored for the integration into the sugar-manufacturing process.

Summary: Zeolite N exhibits high selectivity and capacity for ammonium ions, making it suitable for applications such as wastewater treatment. This study investigated various process factors related to zeolite N synthesis scale-up, including reactant solution agitation, mother liquor recycling, zeolite washing strategies, clay source, reactor geometry, and materials of construction. The results showed that agitation did not significantly affect zeolite N formation rate at 120 ?, but promoted it at 100 ?. Mother liquor recycling reduced the need for chemicals and improved product quality. Excessive quartz content in the clay feedstock inhibited zeolite N growth. Using specific materials and reactor types could significantly shorten reaction time.

It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
