    • After a cyclopentadiene compound and a vinyl aromatic compound are thermally polymerized, the obtained copolymer is subjected to a hydrogenation reaction to form a hydrogenated product. After most of the hydrogenation solvent is separated by a solvent evaporation tank from the hydrogenated product, an additive separately prepared by dissolving an antioxidant is added to the hydrogenated product to form a mixture. While the hydrogenation solvent is a naphthenic solvent, the additive is prepared by dissolving the antioxidant in an aromatic additive solvent having the same carbon atoms as those of the hydrogenation solvent. Then, the low-molecular-weight component as well as the remaining hydrogenation solution and the additive solvent are separated by a thin-film evaporator from the mixture. The obtained molten resin is pelletized to produce hydrogenated petroleum resin pellets. The time for uniformly blending the antioxidant can be shortened.
    • 在环戊二烯化合物和乙烯基芳族化合物热聚合之后,将所得共聚物进行氢化反应以形成氢化产物。 在通过溶剂蒸发槽从氢化产物中分离大部分氢化溶剂后,将通过溶解抗氧化剂分开制备的添加剂加入到氢化产物中以形成混合物。 虽然氢化溶剂是环烷溶剂,但是通过将抗氧化剂溶解在与氢化溶剂的碳原子相同的芳族添加剂溶剂中来制备添加剂。 然后,通过薄膜蒸发器从混合物中分离低分子量组分以及剩余的氢化溶液和添加剂溶剂。 将得到的熔融树脂造粒,生成氢化石油树脂颗粒。 可以缩短均匀混合抗氧化剂的时间。

    • High strength presulfided catalyst for hydrogenating hydrocarbon resins without an in situ sulfiding step. The catalyst particles have a supported metal catalyst structure with presulfided interstitial surfaces with about 20 weight percent of a low molecular weight hydrocarbon resin, based on the weight of the porous supported metal catalyst structure, filling from 90 to 95 percent of the pore volume to improve a crush strength of the catalyst particles. The presulfided catalyst can be stored and/or shipped in an airtight container with an inert atmosphere. The catalyst particles are made by preparing the oxidized catalyst, presulfiding the catalyst, contacting the catalyst with the low molecular weight hydrocarbon resin in an inert atmosphere, sealing the catalyst in a storage/shipping container, loading the reactor with the presulfided, filled catalyst, and contacting the catalyst with an unsaturated hydrocarbon resin under hydrogenation conditions.
    • 用于氢化烃树脂而没有原位硫化步骤的高强度预硫化催化剂。 催化剂颗粒具有支撑的金属催化剂结构,具有预硫化的间隙表面,基于多孔载体金属催化剂结构的重量,约20重量%的低分子量烃树脂,填充孔体积的90至95%以改善 催化剂颗粒的压碎强度。 预硫化的催化剂可以在具有惰性气氛的气密容器中储存和/或运输。 催化剂颗粒通过制备氧化催化剂,预硫化催化剂,在惰性气氛中使催化剂与低分子量烃树脂接触,将催化剂密封在储存/运输容器中,将反应器装载在预硫化的填充催化剂中, 并在氢化条件下使催化剂与不饱和烃树脂接触。
