Preparation method for Carbon 5/Carbon 9 hydrogenated petroleum resin
The invention discloses a preparation method for Carbon 5 / Carbon 9 hydrogenated petroleum resin. In the existing preparation methods, certain methods have extremely high requirements on devices and high cost, and catalysts used by certain methods are not ideal for aromatic ring hydrogenation effect or easily cause intoxication. The preparation method comprises the following steps: firstly dissolving Carbon 5 / Carbon 9 petroleum resin by a dissolvent, then carrying out centrifugal sedimentation on the carbon 5 / Carbon 9 petroleum resin so as to remove most insoluble gel and asphaltenes, filtering the carbon 5 / Carbon 9 petroleum resin in an absorption tower filled with fillers so as to remove remained insoluble gel, asphaltenes and heavy metals; carrying out medium pressure hydrogenation reaction on liquid obtained through filtration in a static bed filled with secondary hydrogenation catalyst; and finally, carrying out flash evaporation and steam stripping so as to remove solvent in the product. The preparation method adopts a macroporous catalyst carrier; fluids are not easily blocked in holes, thereby greatly reducing fluid pressure drop and increasing effective catalytic area; and secondary hydrogenation can be completed in medium pressure, thereby greatly reducing requirements on devices and investment cost of the devices and obtaining hydrogenated petroleum resin with high quality.
