The invention provides a preparation method of pseudo-boehmite with centralized pore size distribution. The preparation method comprises the following steps: neutralizing and gelatinizing an aluminum source compound under normal pressure, adding obtained slurry into a reaction kettle, and performing hydro-thermal treatment at the temperature of 100 to 200 DEG C for 0.5 to 24h; after the reaction is finished, performing solid-liquid separation and washing to obtained slurry to obtain an impurity-removed product namely a filter cake; drying and crushing the filter cake to obtain the pseudo-boehmite with the centralized pore size distribution. A preparation process is simple, and the method is low in cost and suitable for industrial production; by controlling hydro-thermal reaction conditions, a series of high-performance pseudo-boehmite products with the centralized pore size distribution can be prepared, and are suitable for serving as multiple types of catalyst carriers and have a wide application prospect.
