以十氢萘为溶剂，通过增加升温过程中的低温搅拌，强化十氢萘对沥青质的解聚和分散作用，提高沥青质加氢过程中在催化剂微孔中的扩散性能。研究表明：在373 K时恒温搅拌1 h，可以使沥青质加氢反应的转化率提高14．97百分点，焦炭产率降低2．68百分点；残渣油收率降低3．01百分点，四组分组成发生明显变化，饱和分、芳香分和胶质的含量均增加；硫、氮脱除率也有不同程度的提高。低温搅拌过程改变了沥青质的存在状态，有利于沥青质的加氢转化反应。

Asphaltene exists in residue in form of large molecular aggregates and it is difficult to dif-fuse and react in catalyst microporous. Tahe atmosphere residue was used as test material to see the effect of stirring on hydrotreatment results. It is found that by addition of a constant-temperature stir-ring process at 373 K for 1 h before the residue hydro-treatment,the diffusibility of asphaltene in cata-lyst microporous is improved due to the depolymerization and dispersion of decalin for asphaltene. Com-pared with the results without stirring,the stirring process can make asphaltene conversion increase by 14. 97 percentage points,the coke yield decrease by 2. 68 percentage points,and the hydrotreated resi-due amount also decreases. The four components of hydrotreated residue undergo a significant change:the saturate,aromatic,and resin are increased. The removal of sulfur and nitrogen is improved to dif-ferent degrees. It is demonstrated that the structure state of asphaltene is changed by stirring and that the addition of the stirring step is beneficial to hydroconversion of asphaltene.
