Problems solved by technology

However, in the solid acid alkylation process, since the solid acid catalyst is easily deactivated, in order to maintain a certain reactivity, frequent regeneration operations are required. Therefore, it is necessary to develop a reactor technology that can realize the continuous reaction and regeneration process. It is very important to promote the development of solid acid alkylation technology

Embodiment 1

[0052] in the attached figure 1 The solid acid alkylation reaction is carried out on the moving bed experimental device shown. Among them, the inner diameter of the shell of the radial moving bed reactor 1 is 600mm, the height of the reaction bed is 3.5m, the height of the regenerator 2 is 600mm, and the height of the reaction bed is 3.5m; there are three reactors from top to bottom. A reactor and two regenerators, the reactor and the regenerator have basically the same dimensions, and are arranged at intervals in sequence. The regenerated material discharge port on the top of the catalyst regenerator is located at 85% of the straight pipe section of the catalyst regenerator from bottom to top, and the regenerated material inlet is located at 5% of the straight pipe section of the catalyst regenerator from bottom to top. The outlet of the plug-in pipe is located at 80% of the straight pipe section of the catalyst regenerator from bottom to top. The fresh raw material for the...

Abstract

The invention relates to a solid acid alkylation reaction and regeneration device and a solid acid alkylation reaction method. The solid acid alkylation reaction and regeneration device comprises at least two stages of moving bed reactors connected in series and at least two stages of catalyst regenerators connected in series, a spent catalyst guide pipe at the bottom of a first moving bed reactorcommunicates with the first catalyst regenerator; a regenerant conveying pipe at the bottom of a first catalyst regenerator communicates with a second moving bed reactor; and a regeneration medium inlet is formed in the bottom of each stage of catalyst regenerator, a regeneration medium outlet is formed in the top of each stage of catalyst regenerator, all stages of catalyst regenerators are connected in series or in parallel through a regeneration medium pipeline, each moving bed reactor is provided with a reaction material inlet and a reaction material outlet, and all stages of moving bed reactors communicate in series through a reaction material pipeline. The solid acid alkylation reaction method provided by the invention can be continuously and stably operated, and the operation flexibility of the device and the economic benefit of operation are improved.

Description

technical field [0001] The invention relates to a liquid-solid series moving bed reaction and regeneration device and a solid acid alkylation method, more specifically, to a liquid-solid moving bed reaction and hydrogen regeneration used in the solid acid alkylation reaction process A device and a solid acid alkylation reaction and regeneration method. Background technique [0002] At present, one of the most important tasks of the oil refining industry is to provide transportation fuel. As an important transportation fuel, gasoline is widely used in transportation and other industries. With the increase of gasoline consumption and increasingly stringent environmental protection standards, how to solve the problem of clean gasoline production has become a hot topic of research and discussion. [0003] Alkylate is a clean, high-octane gasoline blending component. Under the action of strong acid, isoparaffins (mainly isobutane) and olefins (C3-C5 olefins) react to produce al...
