description Provided are an apparatus for preparing vinyl chloride including: a pyrolysis reactor in which 1,2-dichloroethane and inert solid particles are mixed to generate vinyl chloride and hydrochloric acid; a first separator receiving the vinyl chloride, hydrochloric acid, and inert solid particles from the pyrolysis reactor and separating the vinyl chloride and hydrochloric acid from the inert solid particles; and a regeneration reactor receiving the separated inert solid particles from the first separator and regenerating the inert solid particles by burning the inert solid particles in a high temperature to remove coke deposited on the inert solid particles, wherein the restoration reactor is connected to the pyrolysis reactor to resupply the restored inert solid particles to the pyrolysis reactor, and a method of preparing vinyl chloride using the same. According to the apparatus and the method, the conversion rate can be improved, the productivity can be improved by effectively preventing interruption due to coke deposition, and the thermal efficiency can be enhanced by reusing thermal energy of sold particles heat treated at a high temperature in the regeneration reactor in the pyrolysis.
