Embodiment 1
[0039] By adopting the method of the present invention, three groups of alkylation reaction sections and three-phase separators at the bottom are set, wherein the alkylation reaction section is composed of a packing tube bundle area and a refrigerant microbubble area, and the packing tube bundle is only made of the packing tube bundle of the present invention In the way of internal packing, the refrigerant microbubbles are dispersed in the tube bundle by atomized refrigerant microbubbles, and the atomized refrigerant from the gas-liquid refrigerant aspirator is dispersed into microbubbles, which act on the filler tube bundle. A three-phase separator is connected to the bottom of the reactor to separate vaporized refrigerant, crude alkylate and mixed sulfuric acid. The reaction conditions and results are shown in Table 1 and Table 2, respectively.
Embodiment 2
[0041] By adopting the method of the present invention, three groups of alkylation reaction sections and three-phase separators at the bottom are arranged, wherein the alkylation reaction section is composed of a packing tube bundle area, a refrigerant vaporization area and a refrigerant microbubble area, and the packing tube bundle The structure is composed of a material pre-mixing section and an internal packing section (height ratio 1:12). A refrigerant vaporization section, refrigerant vaporization pipeline and corresponding pressure control system are arranged at the lower part of each group of alkylation reaction sections. The micro-bubbles of the agent adopt the atomized refrigerant micro-bubble dispersion tube bundle, and the atomized refrigerant from the gas-liquid refrigerant aspirator is dispersed into micro-bubbles, which act on the filler tube bundle. A three-phase separator is connected to the bottom of the reactor to separate vaporized refrigerant, crude alkylate...
