is any process of activation yet discovered more effective than mild acid leaching. Synthetic bleaching media, treated slag, and activated alumina will serve other purposes but are not good bleaching agents. The study of bleaching power here recorded included a study of the vapor p1·ess1ue of hydrous clays and of their thermal dehydration. These properties bear directly on their adsorbing ...Get Price
Surface Active Sites and Textural Features of Bleaching Clays
· Essentially, the process of bleaching is aimed at removing contaminants and undesired components from raw oils to preserve taste and impart quality to the oil. As such, clays have been extensively used in bleaching of vegetable oils and fats. The performance of natural clay mineral is dependent on their physical and chemical processing including steps like grinding, screening, acid .Get Price

This process requires approximately lb of clay per gallon of oil. After clay is filtered from the oil, the final steps are neutralization and distillation of the oil. Acid clay treatment was the predominant technology in the past. According to the US DOE study, there were 150 rerefiners using Acid/Clay in 1960 processing 300 million gallons per year. In 1976, it dropped to 25 active re ...Get Price
