Activation and regeneration method of deactivated catalyst in catalytic combustion process of chlorine-containing VOCs (Volatile Organic Compounds)

The invention provides an activation and regeneration method of a deactivated catalyst in a catalytic combustion process of chlorine-containing VOCs (Volatile Organic Compounds), and relates to the technical field of air pollution control. The activation and regeneration method provided by the invention comprises the following steps: performing surface water activation on a deactivated catalyst to obtain a preliminarily activated catalyst, wherein the deactivated catalyst is a composite metal oxide catalytic material taking solid acid HZSM-5 as a carrier; and mixing the preliminarily activated catalyst with a regeneration solution to obtain an activated regenerated catalyst, wherein the solute in the regeneration solution comprises composite metal salt. According to the method, the rebuilding of the acid site on the surface of the deactivated catalyst and the regeneration of the metal oxide can be realized in two steps, and the activation and reutilization of the catalyst are realized. 本发明提供了一种含氯VOCs催化燃烧过程中失活
