Claim 5:
6. The preparation method according to claim 5, comprising:
heating a first mixture comprising the carbon material and the ferric salt to 600-1000° C. at a temperature raising rate of 5° C./min-10° C./min in an inert atmosphere to be roasted for 1-4 h to obtain a zero-valent iron modified carbon material; and
heating a second mixture comprising the zero-valent iron modified carbon material and the organic phosphorus to 600-1000° C. in the inert atmosphere to be roasted for 1-4 h to obtain the catalyst for continuous production of the 1,1,1,3-tetrachloropropane through the gas-solid reaction.
