向绥中36-1常压渣油中分别加入催化裂化油浆和减四线抽出油,研究了其对渣油胶体稳定性的影响.结果表明,加入两种油品后,体系的稳定性均呈下降趋势;不同油品对渣油胶体稳定性的影响程度不同,加入减四线抽出油后体系的稳定性比加入催化裂化油浆时高.从SARA组成、极性两方面考察了不同性质油品对混合体系胶体稳定性的影响.结果表明,SARA组分的变化对混合体系的胶体稳定性有影响,但不是影响其稳定性的主要因素,组分极性上的差距是造成混合体系稳定性变化的主要原因.

FCC slurry oil and HVGO were added to Suizhong atmospheric residue,respectively.The effect of various heavy oil fractions on the colloidal stability of residue system was studied by mass fraction normalized conductivity method.Results indicated that the addition of these two fractions in atmospheric residue exhibited negative effect on the colloidal stability of residue system,and the negative effect of adding FCC slurry oil was stronger.By analyzing the SARA compositions and polarities of these heavy fractions and atmospheric residue,it was found that both the composition variation and polarity variation affected the colloidal stability of residue system,yet the later was the main factor.The disparity in polarity between heavy fraction and residue was the main cause of altering the colloidal stability of residue system.
