The pore size of the chabazite structure is exceptionally suitable for methanol to olefins (MTO) reaction. reaction has an induction period required formation a hydrocarbon pool (HP), usually composed aromatic compounds different sizes. HP alkylated by and afterward cracked, leading olefins. Despite importance HP, its growth in are exceedingly dependent on porosity catalyst. ideal that formed r...

In order to improve the sustainability and productivity of modern agriculture, it is mandatory enhance efficiency Nitrogen (N) fertilizers with low-impact natural strategies, without impairing crop yield plant health. To achieve these goals, ZeOliva project conducted an experiment using a zeolite-rich tuff as soil amendment N allow reduction their inputs. The results three years experimentation...

The capture of low concentration CO2 presents numerous challenges. Here, we report that zinc containing chabazite (CHA) zeolites can realize high capacity, fast adsorption kinetics, and desorption energy when capturing ca. 400 ppm CO2. Control the state location ions in CHA cage is critical to performance. Zn2+ loaded onto paired anionic sites six-membered rings (6MRs) are primary adsorb 0.51 m...

The Italian zeolitic tuffs have been intensely exploited by family companies and are used, mainly, as building, insulation decorative stone, whereas the fine powder resulted during cutting of blocks is used for feedstock soil amendment. XRD, XRF SEM/EDS techniques applied to study samples collected from quarries Naples, Bolsena Sorano areas. Two different types chabazite, identified; a Ca-rich ...

Construction waste, produced from building projects, was utilized to prepare chabazite by alkali fusion hydrothermal synthesis method. The synthesized used as an adsorbent for the removal of methylene blue (MB). XRD, FTIR, and N2 adsorption/desorption curves were adopted describe physical chemical properties samples. results show that possesses crystalline structure, typical functional groups, ...

Phillipsite has formecl from volcanic glass in saline, alkaline lakes both saturated and undersaturated with respect to gaylussite and trona. It has also formed from volcanic glass in saiine, alkaline soils of Olduvai Gorge, Tanganyika. Phillipsite occurs both as lath,shaped and as equant crystals, which are commonly zoned lvith refractive indices ranging between 1.438 and 1.490. Molecular SiOz...

This paper compares the alkali-activated fly ash (AAFA) manufactured with thermal oven curing and pulsed microwave curing methods. Fly ash activated by 8M NaOH solution at a liquid to solid ratio of 0.3 was cured by thermal oven at 85°C and domestic microwave oven, respectively. Apart from compressive strength test, the temperature profiles of AAFA samples were captured by thermal camera. React...
