The invention discloses a sectional feed alkylation reactor and an alkylation reaction method. The reactor comprises a reactor cylinder, a sealing head, a partition plate, an upper bed layer, a rotating bed, a composite bed layer, a feed pipe, a feed distribution pipe, a rotating shaft, a material supply inlet, a discharge outlet, a circulating cooling gas inlet and a circulating cooling gas outlet. The invention further provides an alkylation reaction method, which comprises the following steps: by adopting the sectional feed alkylation reactor, iso-butane and concentrated sulfuric acid are firstly mixed to form acid hydrocarbon emulsion in the upper bed layer, then the hydrocarbon emulsion and mixed hydrocarbon, entering from the material supply inlet, enter the rotating bed for performing alkylation reaction, and the reacted material can realize the demulsification process of the emulsion in the composite bed layer.
