Stablization and partial deasphalting of thermal residues by chemical treatment. P. de Filippis, C. Giavarini and M. Scarsella. Energy and Fuels, January-February 1994, 8(1), 141--146.
Thermal residues and bitumens obtained from visbreaking and thermal cracking were stabilized by reaction with small amounts of phosphoric acid to flocculate the more unstable and heavy asphaltene, which is removed by settling or centrifugation. A flow chart of the proposed scheme is included. The bitumen products had the same or better rheological properties as the original material while the stability was much improved. 18 refs.
