Provided in the invention are a catalyst for preparing phosgene and a preparation method therefor, and a method for the preparation of phosgene and the comprehensive utilization of energy thereof. The preparation method comprises the following steps: 1) stirring and soaking activated carbon in a modifying solution, then adding dimethyltin dichloride and chromium oxide powders and carrying out a reaction, and then adding a nickel oxide fine powder and ultrasonically oscillating same to prepare a pre-modified activated carbon; 2) drying the pre-modified activated carbon; and 3) heating and calcinating the dried pre-modified activated carbon from step 2) to prepare the catalyst. Based on the preparation method, thin layers are formed on the surface of the catalyst by bonding chromium tin phosphate and chromium tin silicate with Ni by means of —O—Ni—O—, respectively, which can improve the high-temperature resistance and oxidation resistance of the activated carbon, and improve the safe and stable operation level of a device. The aim of integrated comprehensive utilization of energy is achieved by coupling phosgene production with an evaporation and concentration process of brine and using steam as a heat source for evaporation and concentration of the brine.

The present invention provides a nanocarbon-iron composite system which is a composite structure formed by interaction of acid-treated nanocarbon serving as a carrier, with and ferrous ions and/or ferric ions in an iron salt.

Accordingly, the present invention further provides a preparation method of the nanocarbon-iron composite system, use of the nanocarbon-iron composite system in preparation of a drug for treating solid tumors, and a suspension for injection based on the nanocarbon-iron composite system.

Methods for treating an industrial byproduct, such as spent, granular, activated carbon, dredge spoils, or contaminated soils involve integrated steps to clean, concentrate, separate and/or otherwise collect hazardous and/or desired materials from such industrial byproducts. The cleaned, concentrated, separated, or collected materials may involve sufficient quantities to be useful to subsequent processors, raw materials, additives, and the like. Other treatment methods involve retaining the clean material stream at sufficient temperatures for sufficient time to separate and concentrate desired material for recovery therefrom, such as precious metals and rare earth elements.
