The invention relates to a mesoporous chloride scavenging agent and a preparation method of the mesoporous chloride scavenging agent. The mesoporous chloride scavenging agent provided by the invention is sphere-like granules and the diameter of the granules is 1mm to 5mm, wherein 70 percent to 80 percent of pore channels is mesopores of 10nm to 50nm, and a pore volume of the mesopores is 0.2mL/g to 0.44mL/g; the mesoporous chloride scavenging agent is obtained by mixing active aluminum oxide powder and an alkali metal solution to prepare granules, ageing and drying the granules, dipping the obtained granules into an alkaline ammonium salt solution, and activating at a high temperature. Compared with the prior art, when the mesoporous chloride scavenging agent provided by the invention is applied to dechloridation of reformed hydrogen or a reformed generated oil product containing an olefin component, the mesoporous chloride scavenging agent has a service life which is longer than that of an existing dechlorin
