PURIFICATION OF LIQUID SUBSTANCES, PARTICULARLY PETROLEUM AND FRACTIONS OF PETROLEUM FROM METALS, ORGANIC COMPLEXES AND OTHER IMPURITIES

摘要

Method for purification of liquid substances, especially petroleum and petroleum fractions from impurities of different kind, such as metals, metallic compounds, organic complexes etc. The purpose is to provide a method by which in a simple and inexpensive manner is obtained a purification of liquid substance, especially petroleum and petroleum fractions from impurities of different kind, such as metals, metallic compounds, organic complexes. This is obtained by bringing said substance in contact with a porous calcium silicate material in crushed form under such conditions with regard to contact time, temperature etc. that an adsorption/absorption of the impurities in question to said calcium silicate hydrate material takes place, and that then the purified substance is separated from the solid calcium silicate hydrate material.
