针对仪长管输原油渣油（简称仪长渣油）的性质特点，开发了新型渣油加氢降残炭催化剂，并考察了加氢工艺条件对仪长渣油加氢处理反应的影响。通过选用镍钼型活性金属体系，改进载体的制备方法、浸渍工艺过程及添加助剂等开发了新型渣油加氢降残炭催化剂，使用该催化剂的级配体系具有更强的加氢饱和活性及杂原子脱除活性。在相同的操作条件下，与现工业装置应用的催化剂级配体系相比，使用新型加氢降残炭催化剂的级配体系可以使仪长渣油的残炭降低率提高3.3百分点、加氢脱氮率提高7.9百分点，有效提升仪长渣油的加氢生成油品质。在渣油加氢常规操作范围内，通过提高反应温度和氢分压、降低体积空速可以提高仪长渣油残炭降低率，促进加氢脱硫、加氢脱氮等反应的进行，有利于加氢生成油品质的提高。

Based on the characterization and hydrotreating reactivity of Yichang residue,a new hy-drotreating catalyst for reduction of Conradson carbon residue (HDCCR)was developed by adopting Ni-Mo active metals and optimizing pore structure of the supports and adj usting the impregnation process,and adding promoter. The experimental results show that the residue hydrotreating layered catalyst system with the new HDCCR catalyst displays the higher HDCCR,HDS and HDN activities compared with the system with original HDCCR Co-Mo catalyst.Under the same reaction conditions, the carbon residue reduced rate increases by 3.3 percentage points,HDN rate increases by 7.9 percent-age points.It is found that high reaction temperature,high hydrogen partial pressure and low volume space velocity improves HDCCR,HDS and HDN activities and thus improves the hydrotreated residue quality.
