A Φ3 to 4 spherical H0.5Cs2.5PW12O40/SiO2 catalyst (obtained by: H0.5Cs2.5PW12O40 powder and wide hole silica gel powder having a particle size of less than 200 mesh were on a mixer thoroughly mixed, and then, ball-formed on a coating machine by using silica sol as the binder, and then dried, calcinated) was sandwiched between titanium wire mesh corrugated plates, and produced into a cylindrical structured packing having a diameter of 50 mm and a height of 50 mm. The packing type catalyst L was loaded into the middle part of a model reaction tower (with a height of 1 m, corresponding to a theoretical plate number of 12), above and below which there was each loaded 1950 mL of a glass spring packing having a diameter of 4 mm and a height of 4 mm (with a loading height of 1 m, corresponding to a theoretical plate number of 15). Cyclohexene and benzene via a dosing pump were pumped respectively into a preheater and preheated and then introduced into the reaction tower, adjusting the heating at the bottom and the reflux rate at the tower top to continuously conduct the reaction, the steady-state reaction conditions and reaction results were listed in Table 3.
