| description | The invention discloses a method for preparing a mercury-free catalyst by adding dichloroethane. The method for preparing the mercury-free catalyst by adding dichloroethane comprises the following steps: 1, soaking mercuric chloride to obtain a mercuric chloride solution; 2, performing acid pickling and water washing treatment on the activated carbon; 3, dipping the activated carbon in a mercuric chloride solution; 4, preparing an auxiliary agent solution, and putting the auxiliary agent solution into the soaking tank to form a semi-finished catalyst; and 5, drying the semi-finished catalyst to form a finished product, in the step (1), adding mercuric chloride into a dissolving tank according to the demand, arranging a corresponding mechanical stirring structure and a steam heating structure in the dissolving tank, then adding a certain amount of industrial hydrochloric acid and a certain amount of clear water into the dissolving tank, stirring mercuric chloride through the stirring structure, and then adding |
