The textile industry has experienced significant advances accompanied by the production of large volumes polluted water released into environment, which requires treatment that varies according to nature pollutants. present work aimed at testing 13X type zeolites synthesized from Djebel Debagh DD1, DD2, and DD3 kaolins in order remove dyes other pollutants effluent COTITEX (Batna, Algeria). Sev...

The determination of the thermo-physical properties (density, specific heat capacity, and thermal conductivity) hygroscopic reactive solid materials, as those applied in sorption thermochemical storage systems, is not trivial. Lack precision measurement contradictory results make it difficult to enter these parameters programs used for simulating functioning operating scenarios devices. For thi...

Chitosan was used to modify a 13X molecular sieve to improve its cadmium removal capability. After being modified with 2% chitosan-acetate for 2 h at 30 °C, significant uptake of Cd2+ could be achieved. The uptake of Cd2+ on the modified 13X molecular sieve followed the Langmuir isotherms with a capacity of 1 mg/g. The kinetics of Cd2+ removal by modified 13X molecular sieve followed a pseudo s...

The effect of the duration adsorption step and purge flowrate on performance a demand-driven pressure swing unit (PSA) was investigated. These two operating parameters were varied examined by simultaneously varying requested total productivities (demand) using model for biogas upgrading. considered PSA application uses FAU zeolite (13X) to separate CH4 CO2. is tracked three key indicators (KPIs...

Most of the solids used in adsorption processes are heterogeneous and most isotherm models are not derived to use information about the solid structure and energy heterogeneity. A possible alternative is to use molecular simulation techniques, which turn the thermodynamic model more microscopic. Then, starting from information on the solid structure, it is possible to develop appropriate solid ...

Metal organic frameworks (MOFs) built from a single small ligand typically have high stability, are rigid, and have syntheses that are often simple and easily scalable. However, they are normally ultra-microporous and do not have large surface areas amenable to gas separation applications. We report an ultra-microporous (3.5 and 4.8 Å pores) Ni-(4-pyridylcarboxylate)2 with a cubic framework tha...

Aluminophosphate monoliths with high CO 2-over-N 2 selectivity and CO 2 capture capacity. Access to the published version may require subscription. a Monoliths of microporous aluminophosphates (AlPO 4-17 and AlPO 4-53) were structured by binder-free pulsed current processing. Such monoliths could be important for carbon capture from flue gas. The AlPO 4-17 and AlPO 4-53 monoliths exhibited a te...
