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 as attached figure 1 The solid acid alkylation reaction was performed on the moving bed experimental setup 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 reactions from top to bottom. The outer dimensions of the reactor and the regenerator are basically the same, and they are arranged at intervals. The regenerated material discharge port at 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 reaction is a mixture of iso...

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 particularly, to a liquid-solid moving bed reaction and hydrogen regeneration for the solid acid alkylation reaction process Device and a solid acid alkylation reaction and regeneration method. Background technique [0002] At present, one of the main 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 the increasingly strict environmental protection standards, how to solve the problem of clean gasoline production has become the focus 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 form alkylated oils dominate...
