LIQUID CATALYST COMPOSITIONS FOR DESULFURIZATION

摘要

PURPOSE: A liquid catalyst compositions for desulfurization is provided to improve the continuance of the desulfurizing performance by improving the stability of liquefied desulfurizing catalyst. CONSTITUTION: EDTA(Ethylenediamine Tetraacetate) chelate catalyst solution Fe(NO3)3·9H2O(404.44g/mol, 98%) 5.15g is melted in 500mL distilled water. The Na-4-EDTA·4H2O(452.24, 99%) 6.85g is dissolved in the mixed solution. Na2CO3 powder is added to the mixture. The pH of mixture is controlled by 8.5. The distilled water is added to mixture. The EDTA chelate catalyst solution is manufactured. The pH of the chelate catalyst solution is controlled with the mixture of dihydrogen phosphate sodium, potassium phosphate dibasic, and monobasic potassium phosphate.
