%X 为提高沸腾床渣油加氢装置的稳定性，实现渣油高转化率下，装置的长周期稳定运行，本文考察了催化剂孔结构及酸性质的变化对生成油稳定性的影响。催化剂的高压釜活性评价结果表明：1) 在酸含量不变的情况下随着催化剂的比表面积的增大，渣油转化率逐渐提高，生成油稳定性逐渐降低；2) 提高催化剂酸含量，渣油转化率也会逐渐提高，但生成油稳定性先升高后降低；3) 催化剂的比表面积增大的同时提高酸含量，渣油转化率由76.7%提高到83.9%，生成油稳定性也有所提高。综上，催化剂的孔结构与酸性质合理匹配，相互协同下可以实现渣油高转化的同时，具有较高的生成油稳定性。
In order to improve the stability of the ebullated-bed residue hydrotreating unit and realize the long-term stable operation with high residue conversion rate, the effects of pore structure and acidic properties of the catalyst on the stability of the hydrogenated oil were investigated. The results of evaluation used autoclave showed that: 1) With the increase of the specific surface area of the catalyst, the residue conversion rate increases gradually, and the stability of the hydrogenated oil decreases gradually; 2) With the increase of acid content of catalyst, the conversion rate of residual oil will gradually increase, but the stability of the hydrogenated oil will increase and then decrease; 3) With the increase of the specific surface area of catalyst, the acid content was increased, the conversion rate of residual oil was increased from 76.7% to 83.9%, and the stability of the hydrogenated oil was also improved. In summary, the pore structure and acidic properties of the catalyst match reasonably, which can achieve high residue conversion ratel and high stability of the hydrogenated oil.
