ACCELERATING THE PURIFICATION OF PARAFFIN IN POWDERY ADSORBENTS USING ULTRASOUND. METHODS OF EXTRACTING PARAFFIN AND CERESINS FROM OIL.
Abstract
Paraffins are refined to remove coloring and volatile matter, as well as odorous matter. Paraffin cleaning is carried out by acid-base method, using adsorbents (contact or percolation), as well as hydrocleaning. The dark color of paraffin before cleaning is explained by the presence of resinous, sulfurous, nitrogenous and other substances, as well as dark products formed from unsaturated and aromatic hydrocarbons.
