摘要： The present invention relates to a support structure of a solid catalyst for preparing a linear alkyl aromatic compound, particularly linear alkylbenzene (LAB), and to a method of preparing an alkyl aromatic compound by alkylating an aromatic compound with an olefin using a solid alkylation catalyst, and of regenerating the deactivated solid alkylation catalyst. The present invention provides an integrated method of preparing an alkyl aromatic compound by alkylating an aromatic compound with an olefin using a filter structure as a solid catalyst carrier for alkylating an aromatic compound with an olefin, and of regenerating the deactivated solid alkylation catalyst, thereby realizing simpler and less expensive processing than conventional processes.
