Embodiment 1
[0040] Such as Figure 1-4 As shown, the device for hydrogenation of modified rosin and C9 / C5 petroleum resin in the transcritical reaction system includes: dissolution kettle 1, hydrogenation reactor 2, expander 3, gas-liquid separator 4, absorption tower 5, permeation Flat compressor 6, solvent pump 7.
[0041] The discharge port of the dissolution tank 1 is connected with the feed port of the hydrogenation reactor 2, and the dissolution tank 1 is used for dissolving raw materials required for production. The hydrogenation reactor 2 is cylindrical. The upper part of the hydrogenation reactor is provided with a feed inlet 21, a gas outlet 22, and the bottom is provided with a discharge outlet 23. The hydrogenation reactor 2 includes a heating pipe 24, which is a heating coil. It is arranged inside the hydrogenation reactor; the gas distributor 25 includes an air inlet 251 and a plurality of nozzles 252 for exhaust; the expander 3 is connected to the gas outlet of the hydroge...
Embodiment 2
[0050] The reaction unit that uses is identical with embodiment 1, a kind of transcritical reaction system hydrogenation modified turpentine and C9 / C5 petroleum resin method, comprises the following steps:
[0051] (1) Prepare raw materials, use turpentine and C9 / C5 petroleum resin as raw materials, mix its hydrogenated turpentine and modified bentonite loaded nickel, add turpentine, C9 / C5 petroleum resin and solvent in a mass ratio of 1:3:1, The amount of nickel loaded on the modified bentonite is 10% of the total mass of turpentine and C9 / C5, put it into the dissolution kettle 1, and heat to dissolve;
[0052] (2) Hydrogenation reaction, put the mixture prepared in step (1) into the hydrogenation reactor 2, then heat the temperature up to 150°C, and fill the hydrogenation reactor with a molar ratio of H 2 :CO 2 = 1:1 mixed gas until the pressure is 10.0MPa, continue to heat up to 250°C;
[0053] (3) Maintain the pressure in the hydrogenation reactor 2 to be 10.0MPa, open t...
