Embodiment 1
[0048] according to figure 1 Shown flow process prepares C5 hydrogenated petroleum resin raw material, concrete steps are as follows:
[0049] (1) Lanzhou Petrochemical ethylene cracking C5 (see Table 1 for material composition) (flow rate: 400kg / hr) is sent to the de-C4 tower T101 to remove light hydrocarbon fractions below C4, and light hydrocarbon fractions below C4 are obtained at the top of the tower T101- OUT (see Table 1 for the composition of the material), the material R1-IN (see Table 1 for the composition of the material) obtained from the tower reactor to remove the light hydrocarbon fraction below C4, wherein the operating parameters in the tower are shown in Table 2;
[0050] (2) Send the material R1-IN obtained in step (1) to remove light hydrocarbon fractions below C4 into the dimerization reactor R1, and the material T102-IN after dimerization (see Table 1 for the material composition), wherein, the column Internal dimerization conditions are shown in Table 2...
Embodiment 2～3
[0057] The C5 hydrogenated petroleum resin raw material was prepared according to the method of Example 1, the difference is that the mixing ratio of the 5 stocks in step (7) has a certain change, as shown in Table 2, and the rest of the conditions are the same.
