Optimization of Bleaching Process - American Oil Chemists
Bleaching clay base minerals. Bentonite minerals have limited sorptive properties in the natural state and require chemical treatment by acids to create the surface area and porosity needed for bleaching vegetable oils. Bleaching clays of this nature are commonly referred to as “acid” or “acid-activated” clays.
Bleaching of Vegetable Oil using Organic Acid Activated
Bleaching of Vegetable Oil using Organic Acid Activated Fuller’s Earth (Bentonite Clay) By Atif Khan University of Engineering and Technology, Pakistan Abstract - Vegetable oil is one of the basic food items which is consumed by almost every human being in this universe.
Bleaching Process, Oil Bleaching Process, Crude Oil Bleaching
The purpose of Bleaching is to remove the color pigments contained inside Vegetable Oils. The neutralized oil is heated at additional temperature through thermic boilers to ultimately raise the temperature of oil upto 120 C to 130 C. The oil is then treated with Bleaching Clays that adsorb the color pigments.
Assessing the bleaching capacity of some Cameroonian clays
Kinetic studies show that the best temperature and contact time for optimum bleaching of vegetable oil varied with the type of oil; these are: 95 °C and 2.5 h for palm oil, 85 °C and 0.25 h for cottonseed oil, and 85 °C and 0.5 h for maize germ oil.
Bleaching Clay Industry Trends & Opportunities
Crude oil refining includes degumming, neutralization, bleaching, deodorization, and further refining. Bleaching clay is widely used in the edible oil and fat industry in the decolorizing and refining process. Crude oil is bleached with natural or acid-activated clay minerals to absorb coloring components and to decompose hydro-peroxides.

Solvent efficiency for oil extraction from spent bleaching clay
In purifying vegetable oil, the quantity of used bleaching clay is 0.5-1% of the oil weight, with its exact amount depending on the type of the purification process and the used raw oil .
Vegetable oil refining, bleaching and deodorizing process
2. The vegetable oil bleaching process. Vegetable oil bleaching process is also called decolorization process. It is using activated white clay to absorb the pigments of crude oil, and make the color of oil become lighter. The waste white clay will be filtered out by leaf filter.
Method of recovering residual vegetable oil contained
This invention relates to a method of extracting residual vegetable oil from spent bleaching clay used in processing of such oil and in processing of the spent bleaching clay with the oil removed for reuse in the form of an activated carbon/clay mixture. 2. Prior Art Related to the Disclosure

Removal of phosphorus from vegetable oil by acid-activated
Among them bleaching clay or bleaching earth, known also as fuller’s earth, is unique to the bleaching of fats or oils. Apart from the colour, which is the important indicator of bleaching effectiveness, the changes in concentrations of the residual soaps, phosphorus, peroxide and anisidine are associated directly with the bleaching process.
Regeneration of Spent Bleaching Clay
Spent clay resulting from bleaching degummed American corn oil was obtained from Best Food Inc. at Yanbu and Saudi Vegetable Oil and Ghee Company (SAVOLA) in Jeddah. The bleaching clay consists mainly of alumino-silicate minerals. All the solvents used in this study were 99+% purity. 2.2 Spent Clay Regeneration by Solvent Extraction
