We are experts in bleaching earths made from highly adsorptive clays
Over the years, we have developed a full range of bleaching earths. This range includes Natural Bleaching Earths (NABE), Surface Modified Bleaching Earths (SMBE) and High Activated Grades (HPBE).
We are experts in bleaching earths based on highly adsorptive clays (bentonite, sepiolite and attapulgite) formed by small particles with highly porous inner structure, which is very active in terms of interaction with other particles organic compounds.
It is essential to understand that depending on the ingredients incorporated in the Bleaching Earth formulas, some characteristics will vary, such as the level of absorption achieved or their capacity to absorb certain undesirable compounds in the oil refining process.
This may seem obvious, but on many occasions this is not taken into account when choosing a Bleaching Earth product. The different minerals used when developing our bleaching earths allow us to provide products with the different absorption rates and adsorption characteristics needed for each feedstock.
