[0036] Examples 1 to 3

[0037] using as figure 1 In the reactor of the shown structure, the gap distance between the upper bed and the lower bed is 100 mm. The total width of the slot of the upper bed stationary component and the rotating component is 1 / 3 of its circumference. The rotating assembly and the stationary assembly are respectively set with three layers, the overlapping position of the stationary toothed ring assembly and the rotating toothed ring assembly is 1 / 2 of the total bed height, and the gap distance between the stationary toothed ring assembly and the reactor shell is 50mm. The gap distance between the stationary toothed ring assembly and the rotating toothed ring assembly is 50 mm, and the thickness of the stationary toothed ring assembly is 0.5 times the thickness of the rotating toothed ring assembly. The lower bed rotating bed is composed of stainless steel wire mesh packing, the bed void ratio of the stainless steel wire mesh packing is 0.95, and t...

Abstract

The invention discloses a sectional feeding type alkylation reactor and an alkylation reaction method. The reactor comprises a reactor barrel body, a seal head, a separating plate, an upper bed layer, a lower bed layer, a feeding pipe, a fed material distributing pipe, a rotating shaft, a supplementing material inlet, a discharging opening, a circulating cooling air inlet and a circulating cooling air outlet. The invention further provides the alkylation reaction method adopting the sectional feeding type alkylation reactor. The alkylation reaction method comprises the following steps: preparing acid hydrocarbon emulsion through iso-butane and concentrated sulfuric acid in the upper bed layer, and then entering a rotating bed at the lower bed layer together with mixed hydrocarbon which enters through a supplemented material inlet, so as to perform alkylation reaction.

Description

technical field [0001] The invention relates to an alkylation reactor and an alkylation reaction method, in particular to an alkylation reactor and an alkylation reaction that adopts isobutane and C3-C5 olefins to feed in stages to catalyze the alkylation reaction. chemical reaction method. Background technique [0002] With the development of the economy, especially the rapid development of the transportation industry, the emission of vehicle exhaust is one of the main sources of air pollution. Improving the quality of gasoline is the most important way to reduce the pollution of vehicle exhaust. The alkylated oil obtained by the alkylation reaction of isobutane and C3-C5 olefins has the characteristics of no sulfur, high octane number, small difference between the octane number of the research method and the octane number of the motor method, and is a high-quality An important blending component of clean gasoline. [0003] Alkylation reaction is a traditional technology ...
