This study deals with the synthesis and characterization of low-silica zeolite X, from calcined Kalabsha kaolin, for adsorption of Zn(II) ions from aqueous solution. The synthesis processes is performed under hydrothermal treatment in alkaline solutions.

Kaolinite - Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 4.It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.

CiteSeerX — Preparation of Zeolite Y Catalyst for ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract — Zeolite Y with SiO2/Al2O3 molar ratio of 3.53 was synthesized from kaolin (clay mineral locally found) under hydrothermal condition at atmospheric pressure. The effects of various factors (the amount of water volume added, ageing and crystallization condition) on the structure of the samples were ...

Removal of lead from solution by combination of natural ...

Nov 01, 2011· The porosity of rings prepared with 62.5 wt.% zeolite, 25.0 wt.% bentonite and 12.5 wt.% kaolin, M5, is very low which is due to compaction during extrusion. The variation of data is similar at two calcination temperatures. A sharp increase in porosity of M5 and M10 may be due to formation pores at high temperature.

The curious case of zeolite–clay/binder interactions and ...

The curious case of zeolite–clay/binder ... kaolin and attapulgite) as a binder with zeolites, high-temperatures are used in the pelletization process in order to eliminate the activity of the clay and destroy the surface area, whilst creating meso- and/or macro-porosity.26 However, it has

Preparation of nano pore hydroxysodalite zeolite membranes ...

In this paper, our approach to membrane synthesis is based on hydrothermally converting films of layered aluminosilicates into zeolite films. Preparation method of the Nano pore HS zeolite membranes using by kaolin on mullite support is reported. The pore size of HS zeolite is 0.3 nm, i.e., smaller than that of the MFI zeolite (0.55 nm).

Optimal synthesis of micro/mesoporous beta zeolite from ...

In this work, a micro/mesoporous zeolite beta was synthesized by in situ hydrothermal crystallization method using kaolin clay, an abundant and cheap resource of silicon substrate in the world, as the unique sources of silica and alumina, and the affecting factors of the preparation process, i.e., the ratios of H 2 O/SiO 2, the optimal ...

Kaolin | Al2H4O9Si2 - PubChem

Kaolin is used in paper production, in paints, rubber, plastic, ceramic, chemical, pharmaceutical and cosmetic industries. HUMAN EXPOSURE: Kaolin is a natural component in soil and found in ambient air. Kaolin mining and refining involve considerable exposure and significant exposure is expected in paper, rubber and plastics production.

Synthesis and characterization of zeolite Y and ZSM-5 from ...

Metakaolin was obtained after 6 min of exposure at 600 °C. The metakaolin produced was then used to synthesis zeolite Y and ZSM-5 using conventional hydrothermal treatment and the shortened thermal treatment cycle was shown to be effective for commercial kaolin as demonstrated by the synthesis of zeolite A.
