  • OPTIMIZATION METHOD FOR DIRECTIONAL PREPARATION TECHNIQUE AND EFFICIENT USE OF SEMI-COKE FOR BLAST FURNACE INJECTION
    Publication number: 20260062620
    Abstract: An optimization method for a directional preparation technique and efficient use of semi-coke for blast furnace injection. Firstly, the volatile and the ash content of target semi-coke are preset, and then the volatile and the ash removal percentages of a raw coal are calculated; after ash removal, several sets of dry distillation carbonization temperatures and carbonization times are obtained according to the volatile removal percentage, and the relationships between a combustion rate, abrasiveness, explosiveness and jet flow property and the carbonization temperature are respectively established to obtain the optimal actual carbonization temperature; and semi-coke for blast furnace injection is obtained at an actual carbonization temperature.

  • METHOD FOR DETECTING ASIATICOSIDE AND MADECASSOSIDE IN COSMETICS
    Publication number: 20250290902
    Abstract: Provided is a method for detecting asiaticoside and madecassoside in cosmetics. Asiaticoside and madecassoside are extracted from cosmetics using a mixed extraction solvent of methanol and acetonitrile, and the asiaticoside and the madecassoside are detected by high performance liquid chromatography (HPLC). By controlling chromatographic conditions and selecting a mobile phase with a specific composition, the asiaticoside and the madecassoside in cosmetics can be assayed.
