摘要
Synergism of hydrogen and composition of oils in noncatalytic upgrading of different petroleum residues were analyzed. Residues were upgraded under temperature of 400°C and initial pressure of 4 MPa for 20 min in the presence of hydrogen or nitrogen, respectively. In addition, anthracene was used as chemical probe to quantify the hydrogen-donating ability of the three feedstocks and the contribution of hydrogen gas. Results show that hydrogen has better synergism with the residue that contains more naphthenic aromatic structure, heteroatom, and metals. Moreover, hydrogen activation possibilities limit the effect of the hydrogen solubility of the oils on upgrading.
