Oil absorbant CynerSorb®

CynerSorb diatomite is a versatile treatment for reducing impurities or replacing silica gels and magnesium silicates in biodiesel refining, simplifying your process and reducing oil loss. Diatomaceous earth adsorbent for biofuel filtration Oil and animal fat-based feedstocks used for the production of biofuels often contain a variety of contaminants that need to be removed as part of the refining process. For producers in the transportation market faced with the challenge of turning used cooking oils and waste fats into biodiesel, we’ve developed a surface-engineered diatomite to replace silica gels and magnesium silicates in biofuel refining, simplifying the process, increasing refining capacity and reducing spent filter cake and oil loss. The increasing use of used cooking oils and waste animal fats as feedstocks pose challenges in terms of higher levels of soaps or phospholipids, glycerol and trace metals that need to be removed as part of the refining process. Typically, this is done during a filtration stage via the addition of a synthetic amorphous silica gel or a magnesium silicate. These products have excellent adsorption characteristics but are poor filter aids, causing premature filter blockage and reduced refining capacity. Often, a diatomite filter aid is added to compensate and to keep the filter bed “open”. While this achieves the required increase in filtration capacity, it also adds process complexity and results in additionally spent filter cake and associated oil loss. With these challenges in mind, Imerys has developed CynerSorb® a range of filterable adsorbents to replace silica gels and magnesium silicates in the refining process.
