[0035] use as figure 1 The reactor of the shown structure uses sulfuric acid as a catalyst to carry out the alkylation reaction.
[0036] The molar ratio of isobutane to olefin is 3~10:1; the volume ratio of acid to hydrocarbon is 0.5~2:1; the residence time of the reaction material in the reactor is 1~30 min. The pressure at the bottom of the reactor is 0~0.05 MPa, and the pressure drop of the reactor is 0~0.4 MPa. The reaction temperature was maintained at -3~3°C.
[0037] The reactor structure is as follows: the diameter of the reactor is 50-300 mm, the height is 250-2500 mm, the height of the fiber bed is 10-120 mm, and the height of the silicon carbide bed is 100-1500 mm.
[0038] The specific reaction conditions are shown in Table 1, and the reaction results are shown in Table 2.
