Abstract: To produce high-graded naphthene-base white rubber oil, the three-stage high-pressure hydrogenation process was adopted in the efforts for optimization of catalysts and matching proportions. Non-hydrocarbon compounds and unsaturated keys were deeply removed to maximize reservation of naphthene-base components in rubber oil products. As a result, products of the KNH series were developed on the basis of those efforts. The products have excellent compatibility between rubber and additives and excellent anti - yellowing, low - temperature, safety and environmental performance. The anti-yellowing level exceeded 4. 5 grades. The product becomes a market leader in the naphthene white rubber oil both at home and abroad and helps China establish its presence in the international market in this area.

Key words: high-pressure hydrogenation, rubber oil, anti-yellowing, evaluation of performance

摘要： 为生产高档环烷基白色橡胶油, 采用三段高压加氢工艺, 通过催化剂优选和配比优化, 深度脱除非烃化 合物和不饱和键, 尽可能保留橡胶油产品中环烷烃组分, 研发了KNH 系列产品。该产品具有与橡胶、添加剂优异相容 性, 以及优异的耐黄变、低温和安全环保性能, 耐黄变水平达到4. 5 级以上。产品在国内外市场白色环烷基橡胶油领 域处于领先地位, 为我国该领域走向国际市场提供了有力保障。
