| titleOfInvention | Iron-based catalyst for direct coal liquefaction and preparation method thereof |
| abstract | The invention discloses a direct coal liquefaction iron catalyst and a preparation method thereof. The preparation method comprises the following steps: preparing a ferric salt solution and an ammonia water solution; allowing a ferric salt solution and an ammonia water solution to enter a static mixer for precipitation reaction to form a slurry mixture containing iron precipitate; enabling the slurry mixture containing the iron precipitate to enter an absorption oxidation reactor and be atomized into fog drops, and enabling the coal powder to enter the absorption oxidation reactor, so that the fog drops are in contact with and mixed with the coal powder and are absorbed by the coal powder; subjecting the pulverized coal absorbed with the fog drops to rapid oxidation of first hot air in an absorption oxidation reactor to generate crystal phase transformation, and generating an iron oxide precursor; subjecting the iron oxide precursor to a first hot air to form a pre-dried catalyst; the pre-dried catalyst is passed into a ball mill dryer and subjected to attrition crushing while being subjected to secondary drying with a second hot air to form the catalyst. The method can obtain the coal direct liquefaction catalyst with higher activity with lower cost, water consumption and energy consumption. |
