Claim 16:
17. A method for continuous production of the 1,1,1,3-tetrachloropropane through a gas-solid reaction, comprising:
encapsulating the catalyst for continuous production of the 1,1,1,3-tetrachloropropane through the gas-solid reaction according to claim 1 in a gas-solid fixed bed reactor to form a catalyst bed layer; and
continuously introducing a reaction raw material gas comprising carbon tetrachloride and ethylene into the catalyst bed layer, wherein an inlet pressure of the reaction raw material gas is increased to 0.8-1.2 MPa and a temperature of heating the catalyst bed layer is increased to 80-120° C., and then catalyzing oligomerization to obtain the 1,1,1,3-tetrachloropropane; a volume ratio of the carbon tetrachloride to the ethylene is 1:2-2:1.
