Embodiment 2~13
[0050] The composition of indene-enriched fraction A is as follows: cyclopentadiene 1.0wt%, methylcyclopentadiene 1.0wt%, styrene 4.0wt%, methylstyrene 8.0wt%, dicyclopentadiene (DCPD) 4.0wt% , indene (Indene) 45wt%, CPD-MCPD dimer, methylcyclopentadiene dimer (DMCPD) 8.0wt%, naphthalene 1.0wt%, and the rest are C8-C12 hydrocarbons.
[0051] Put the above-mentioned fraction A after dehydration into the reactor, and add boron trifluoride diethyl ether BF accounting for 0.4-1.5wt% of the total material mass under the condition of -10°C to 25°C (reaction initiation temperature) 3 ·Et 2 O or gaseous boron trifluoride accounting for 0.1-0.8wt% of the total material mass, polymerized at 10-45°C (reaction temperature) for 0.5-3h to obtain an indene resin polymer solution, which was washed with 5% sodium hydroxide solution The catalyst was removed, and then washed with water until neutral to obtain a light yellow resin solution.
[0052] According to the above reaction steps, exampl...

[0058] Firstly, the solvent is removed by vacuum distillation at -0.085MPa to 110°C, and then free fluoride ions and trace water are removed through an electric desalination device, and then the high-efficiency dehalogenation agent spherical Al 2 o 3 (Particle size 0.3cm, pore volume 0.5ml / g, bulk density 900kg / m 3 ) to remove trace fluorine at high temperature, and finally modify zinc oxide (ZnO content 95wt%, MgO content 3wt%, SiO 2 Content 2wt%, specification is Φ4×4-15, bulk density 1.25kg / L) the petroleum resin liquid to be hydrogenated is obtained after removing trace sulfur in packed bed;
[0059] The above-mentioned petroleum resin liquid is dissolved in hydrocracked aviation kerosene with a boiling range of 200-240° C. at a mass ratio of 1:3, and a hydrogenation reaction experiment is carried out under the action of a hydrogenation catalyst with a limited composition. Mass percentage of each component in hydrogenation catalyst: carrier γ-Al 2 o 3 96.5%, main catal...
