Abstract

The invention discloses a preparing method of hydrogenated C5 / C9 copolymerized oil resin, which comprises the following steps: dissolving C5 / C9 copolymer oil resin in the hydrogenation solvent; decoloring through adsorbing agent to proceed catalytic hydrogenating reaction with hydrogen in the fixed bed reactor at 220-270 Deg C under 2.0-8.0Mpa; setting the bulk air-speed at 0.1-1.0h-1 and hydrogen and oil rate at 300-3000:1; allocating the catalyst as load-patterned nickel catalyst with 35-50% Ni; adopting gamma-Al2O3 as carrier with specific area at 150-300m2 / g and hole conpacitance at 0.2-0.4ml / g; decompressing hydrogenated product; distilling to recycle solvent to obtain the product.

Description

technical field

[0001] The present invention relates to a kind of preparation method of hydrogenated petroleum resin, particularly relate to a kind of hydrogenated C 5 / C 9 Preparation method of copolymerized petroleum resin. Background technique

[0002] Petroleum resin is a by-product of petroleum cracking C 5 、C 9 Distillation is a kind of polymer obtained by catalytic polymerization. Since the first successful development of petroleum resin in the United States in 1945, there have been more and more varieties. According to the different raw materials used for polymerization, it can be divided into five categories (1) C 5 Aliphatic hydrocarbon resins, from C 5 Distillate obtained; (2)C 9 Aromatic hydrocarbon petroleum resins, composed of C 9 Distillate obtained; (3) aromatic hydrocarbon - aliphatic hydrocarbon copolymer resin, also known as C 5 / C 9 Copolymerized petroleum resin; (4) Dicyclopentadiene resin, also known as DCPD resin made from dicyclopentadiene or...
