| Abstract: | In this paper, flocculation and adsorption have been used as an efficient combination for the regeneration of used rolling oil. Polyethyleneimine (PEI) incorporated with polyacrylamide (PAM) as flocculant for treating used rolling oil was examined. The effect of dosages of PEI and PAM was investigated experimentally. The research of a percolation refined adsorption process using different adsorbent materials (silica gel, alumina, and activated carbon) was evaluated. The physical properties and hydrocarbon composition of regenerate oil become similar to the base rolling oil. In addition, the flocculation and adsorption mechanism was also explored. |
