The invention belongs to the technical field of preparation of ethyl benzene through catalytic dry gas, and discloses a preparation method of ethyl benzene by adopting alkylation exhaust gas generated in the process of preparing styrene by adopting catalytic dry gas. The method comprises the following steps: separating ethane, demethanizing, deethanizing, performing oxidative dehydrogenation, dehydrating and depickling, performing hydrocarbylation reaction, and separating ethyl benzene. A preferred adsorbent and the cyclic utilization technology of ethane and the adsorbent can minimize the preparation cost of ethyl benzene, the technology is simple and the recyclability is high. Under appropriate technological conditions, the total conversion rate of ethane can reach above 88%, the overall selectivity of ethylene generating ethyl benzene can reach above 80%, the purity of ethyl benzene can reach above 83%, and the recovery rate of the adsorbent can reach above 99%.
