| titleOfInvention | Hydrogenation of petroleum resin processing method |
| abstract | A kind of hydrogenation of petroleum resin processing method, the following steps are included: (1) dissolved Petropols raw material enters the first segment hydrofining reactor of catalyst classification filling, in reaction pressure 8-17.0MPa, 230-270 DEG C of reaction temperature, air speed 0.3-0.7h ‑1 , react under conditions of hydrogen-oil ratio 300-800v/v；The top of the first segment hydrofining reactor loads protective agent, and major catalyst is that non-noble metal sulfided state is catalyst-loaded, and mercaptan-eliminating catalyst is loaded in bottom；(2) first segment reaction product after water washing, gas-liquid separation, be sent into stripper and stripped by liquid stream, further removes hydrogen sulfide；(3) liquid stream after stripping enters second segment hydrogenation dearomatization reactor, contacts with loaded Ni catalyst, in reaction pressure 4-10.0MPa, 230-260 DEG C of reaction temperature, air speed 0.5-0.7h ‑1 , react under conditions of hydrogen-oil ratio 300-800v/v；(4) reaction product obtained in second segment hydrogenation dearomatization reactor after gas-liquid separation, separates solvent and petroleum resin products, is recycled after solvent recovery.This method operating cost is low, high-value product high income. |
