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...
