| titleOfInvention | A kind of gangue-based briquette sulfur fixative |
| abstract | The invention discloses a gangue-based briquette sulfur fixative, which comprises the following raw materials in parts by weight: 50-60 parts of calcium carbonate, 20-30 parts of calcium hydroxide, and 5-10 parts of modified ceramic powder; the modified The active ceramic powder is a ceramic powder loaded with zero-valent iron. The preparation method of the modified ceramic powder is as follows: waste ceramics are pulverized and sieved, soaked in acid or alkaline solution, cleaned with deionized water and dried to obtain ceramic powder after ultrasonic dispersion treatment; the ceramic powder and FeSO 4 7H 2 O was placed in the ethanol solution and stirred under the protection of nitrogen; then NaBH 4 solution was added dropwise, and the stirring was continued under the protection of nitrogen to obtain a dispersion liquid. After the dispersion liquid was filtered, the solid obtained was washed and dried to obtain a ceramic powder loaded with zero-valent iron. The high temperature sulfur fixation rate (1100 DEG C) of the invention can reach more than 75%, and the effect is remarkable; at the same time, the cold mechanical strength and cohesiveness of the molded coal can be improved. |
