METHOD FOR PREPARING LIQUID PETROLEUM PRODUCTS BY DEMETALLIZATION OF HEAVY PETROLEUM RAW

摘要

FIELD: petroleum industry. ^ SUBSTANCE: invention relates to methods for processing petroleum residues in aim for preparing refined raw used in different processes in petroleum processing and to methods for isolating and concentrating heavy metals representing the industrial profit by using adsorbent adding to the reaction mass as a powdered form. For preparing liquid petroleum products a synthetic material is used as adsorbent based on hydroxyapatite of the formula Ca10(PO4)6(OH)2 adding to the reaction mass as a suspension. Demetallization of heavy petroleum raw is carried out in the presence of adsorbent, and process is carried out at temperature 200-250°C. Invention provides enhancing effectiveness, decreasing cost and expanding assortment of contact materials used in processes for adsorption demetallization of heavy petroleum raw. ^ EFFECT: improved preparing method. ^ 6 tbl, 9 ex
