Examples
Embodiment 1
[0027] Fill the appropriate amount of resins I, II and III into four 100mL fixed-bed reactors connected in series. The filling scheme is as follows: 50 mL of resin I for the first reverse loading, with an average pore size of 0.15 nm, and an exchange equivalent of 3.2 mmol / g; 50 mL of resin I for the second reverse loading, with an average pore size of 0.15 nm, and an exchange equivalent of 3.2 mmol / g; The average pore diameter is 0.4nm, and the exchange equivalent is 4.5mmol / g; the four reverse packing resin III is 110mL, the average pore diameter is 5.0nm, and the exchange equivalent is 5.0mmol / g.
[0028] The inlet pressure is 1.2MPa, and the total mass space velocity of raw materials is 0.8h -1 .
Embodiment 2
[0039] Fill the appropriate amount of resins I, II and III into four 100mL fixed-bed reactors connected in series. The filling scheme is as follows: 30 mL of resin I for the first reverse loading, with an average pore size of 0.2 nm, and an exchange equivalent of 3.4 mmol / g; 60 mL of resin I for the second reverse loading, with an average pore size of 0.15 nm, and an exchange equivalent of 3.5 mmol / g; 90 mL of resin II for three reverse loading, The average pore diameter is 0.5nm, and the exchange equivalent is 4.2mmol / g; the four reverse packing resin III is 100mL, the average pore diameter is 7.0nm, and the exchange equivalent is 5.2mmol / g.

Embodiment 3
[0042] Three 100mL series fixed-bed reactors were loaded with appropriate amount of resins I, II and III respectively. The filling scheme is as follows: 110 mL of resin I for one-reverse loading, with an average pore size of 0.12 nm, and an exchange equivalent of 3.3 mmol / g; 100 mL of resin II for second-reverse loading, with an average pore size of 0.3 nm, and an exchange equivalent of 4.8 mmol / g; 120 mL of resin III for three-reverse loading, The average pore diameter is 6.0nm, and the exchange equivalent is 5.4mmol / g.
[0043] The inlet pressure is 1.3MPa, and the total mass space velocity of raw materials is 1.1h -1 .
[0044] Using mixed C4 as raw material, the composition is shown in Table 1. The loading scheme of each example was used to carry out the isobutene superimposition experiment. After the stable operation without inhibitors, the results of the inlet temperature of each reactor and the conversion rate of isobutene are listed in Table 2. . The comparative dat...
