Effect of Catalysts on Oxidation of Ruqigou Coal with NaOCl

Abstract:

The effect of molecular sieve, activated carbon, and nickel-based catalyst on oxidation of Ruqigou coal with NaOCl was investigated. The yields of diethyl ether-soluble fractions from reaction mixture are 67.3% for black test, 71.2% for molecular sieve, 68.6% for activated carbon and 70.3% for nickel-based catalyst, respectively. The results indicate that molecular sieve, nickel-based catalyst and activated carbon can all improve the oxidation reactivity of coal in aqueous NaOCl solution. Molecular sieve and nickel-based catalyst can convert most of the organic matters contained in coal into solvent-soluble species. The catalysis of molecular sieve is the highest, followed by nickel-based catalyst, activated carbon is relatively small.
