摘要在加氢中试试验装置上，以环烷基减压蜡油为原料，考寨了反应温度、氢分压等工艺条件对环保橡胶油CA值、8种多环芳烃(PAHs)等性能的影响。结果表明，在氢分压为10～15MPa，体积空种PAHs质量浓度满足欧盟环保要求的橡胶油。氢分压越高，体积空速越小，加氢工艺生产环保橡胶油的操作空间(反应温度区间)越宽，且偏向低温区间，环保橡胶油的收率越大。

Abstract: In this article, effects of reaction temperature, hydrogen partial pressure and other process conditions on C value, 8 kinds of polycyclic aromatic hydrocarbons (PAHs), etc. of green rubber oil were studied in a pilot trickle-bed reactor by naphthenic vacuum gas oil, The results showed that under the condition of hydrogen partial pressure lo15 MPa, volumetric space velocity between reference to reference + o. 5 h, and reaction temperature between t to t + 6o 'C, it was appropriate for hydrofining process to produce green rubber oil, in which the Ca value was over 12% and mass concentration of benzo(a)pyrene and other PAHs met the EU environmental requirements. There would be a wider operating space (reaction temperature range) for production of green rubber oil by hydrofining process at a higher hydrogen partial pressure, lower volumetric space velocity. What's more, the operating tcmperature range led to lower temperature area, so there would be a higher yield of green rubber oil.

随着对环境保护的日益重视和国内轮胎工业的迅速发展，环保高芳烃含量轮胎用橡胶填充油（以下简称环保橡胶油)的需求呈现快速增长态势。由于轮胎和橡胶行业所使用芳烃油的多环芳烃（(PCA)含量较高，而多环芳烃对生物体具有致癌、致畸作用和生殖毒性，

很多国家的法规中均公认芳烃油是一种具有潜在毒性和致癌性的物质。为了实现化学工业可持续发展的战略目标，欧洲橡胶工业联合协会(BLIC)和国际合成橡胶生产者学会(IISCP)共同宣布：自2010年1月1日起，在轮胎中使用无毒性橡胶油。
