Bleaching clays consist mainly of clay minerals (montmorillonite, beidellite, and saponite) with admixtures of quartz, feldspar, biotite, pyroxene, and other mineral fragments. The predominant particle size is less than 0.01 mm. The clays are distinguished by a high content of water, two-thirds of which is evaporated at 110°C, and by highly ...

 · All clays showed some bleaching ability in the natural state, but activation increased the bleaching power. These clays seemingly are suitable for commercial and industrial uses. Introduction Industrial use of montmorillonitic clay has increased during the last decade (Gunsallus and Brett, 1958, fig. 2).

 · The various clays and synthetic silica mixes removed 20–50% of the carotenoids in the degummed oil, depending on clay concentration and activity. For the two activated clays, pigment adsorption increased with clay amount. Steam refining totally destroyed carotenoids in the clay- treated oils by heat bleaching.

Hydroxyl ions are driven off by heating clay minerals to temperatures of 400°–700° C. The rate of loss of the hydroxyls and the energy required for their removal are specific properties characteristic of the various clay …

Physical Properties Of Clays Plasticity, tensile strength, texture, shrinkage, porosity, fusibility and colour after burning are the physical properties which are the most important in determining the value of clay. Knowledge of these properties is of more benefit in judging the quality of the raw material than a chemical analysis.

 · Sulfuric acid is effective at modifying and improving the textural properties of clays. Therefore, it was selected as the clay modifier in this study. The process was as follows: 30 g samples (USBC or SSBC) were added to a solution of water (54 mL) and concentrated sulfuric acid (9 mL) and mixed at room temperature for 6 h.

 · It might be ascribed to the more complete removal of the moisture, impurities, and dirt by direct heating than by solvent extraction. Moreover, the direct heated-regenerated spent bleaching...

Physical Properties Of Clays . Plasticity, tensile strength, texture, shrinkage, porosity, fusibility and colour after burning are the physical properties which are the most important in determining the value of clay. Knowledge of these properties is of more benefit in judging the quality of the raw material than a chemical analysis.

Bleaching clay plays an important role in refining, bleaching, and decolorizing edible oil. It is also used for removal of phospholipids, sulfuric acid, sludge, sulfonic acid, free fatty acids, and traces of metal in oils. Besides these applications, it is used in effluent treatment plants and as an ingredient in cosmetic products.
