Clay Adsorption Perspective on Petroleum Refining
Bentonite clays promote the highest adsorption capacity to remove sulfur and a high bleaching potential. Attapulgite clay is effective in decolorization and neutralization any In this study, three bleaching clay samples, bentonite clay, kaolinite and Fuller's earth were selected to investigate their ability to remove chlorophyll from Performance of bleaching clays in dechlorophyllisation of

Regeneration of spent bleaching clay by ultrasonic
An effective method that combines solvent extraction with ultrasonic irradiation was developed to recycle spent bleaching clay (SBC) from modern oil refinery The present work addresses the problem of improving the percolation properties of heap leaching piles of clay, slime-oxidised and mixed ores. These ores are Percolation leaching of clay mixed copper ores

如何表征复合导体的渗滤现象（percolation
这种随着导电填料的填充分数增加到某一临界值，导电复合材料的电阻率急遽下降的现象，被称为”渗滤（ percolation ）”，而 填充分数 的这一临界值被称为”渗滤阈值（ percolation threshold ）”。. 研究导电 The present review summarizes the using of clay as adsorbent in several petroleum refining processes such as desulphurization, deasphalting, waste oil recovery, bleaching, corrosion reduction, heavy metals removal and other. One of the simplest, easiest and efficient separation processes used in different industries is adsorption.Clay Adsorption Perspective on Petroleum Refining Industry

Influences of Illumination Pretreatment on Soybean Oil Activated Clay
Visible light has been widely studied for possible applications in food industry as being a kind of clean energy. Presently, the influences of illumination pretreatment on soybean oil quality followed by conventional activated clay bleaching, including the oil color, fatty acid composition, oxidation stability, and micronutrient used clay from the tower periodically and burnt it under controlled conditions so as not to sinter the clay. Clay percolation treatment was broadly used for lubricating oils, but clay contacting has been largely replaced [1]. Several types of clay are obtainable and applied in adsorption to treat the petroleum fractions [2, 6, 9-14].Clay Adsorption Perspective on Petroleum Refining

Microwave-assisted pyrolysis spent bleaching clay for
Spent bleaching clay (SBC) is a waste generated from the refining process of edible oils. SBC contains some residual oils, with excellent potential to produce aromatic bio-oil. For the first time, microwave-assisted pyrolysis was used to treat SBC, which has unique microwave response characteristics.Step-by-step solvent extraction was used to regenerate spent clay by recovering the adsorbed oil in lubricating oil refining clay. Several polar and nonpolar solvents were tested, and petroleum ether (90–120°C) and ethanol (95 v%) were selected as the nonpolar and polar solvents, respectively. The spent clay was first extracted using petroleum ether Regeneration of Spent Lubricant Refining Clays by Solvent

Acid Activation of Clay Minerals ScienceDirect
One of the most common chemical modifications of clay minerals, used for both industrial and scientific purposes, is their acid activation. This consists of the reaction of clay minerals with a mineral acid solution, usually HCl or H 2 SO 4.The main task is to obtain partly dissolved material of increased specific surface area (SSA), porosity and surface In this work, spent bleaching clay (SBC) was treated with ethyl acetate and impregnation with 3-amino-5-hydroxypyrazole (AHIBC) that utilized as economical sorbent material. The uptake of yttrium ions from aqueous solution using AHIBC was studied under batch process as a function of pH of the solution, contact time, adsorbent dosage, Applied Sciences Free Full-Text Adsorption of Yttrium Ions
