Explaining the mechanism of electrochemical processing of some organic wastes

Abstract

The process of electrochemical treatment of acid tars -wastes from sulfuric-acid treatment of white oils -was theoretically substantiated. Its commonality with processing wastes in the form of unsaturated hydrocarbons in electric ionization of π-bonds and their chemical saturation was noted.The orientation toward zero-waste technologies, especially in closed production cycles, has become the basis for development primarily of the chemical industry.A method for electrochemical processing of wastes from sulfuric-acid treatment of white oils, so-called acid tars, was experimentally found [1] and technology [2] for production of asphalt that on the whole corresponds to GOST 6617-76 was experimentally elaborated.A brief theoretical explanation* (substantiation) of the mechanism of the reactions in electrochemical processing of these wastes is given below.Acid tar is an emulsion of a relatively high-molecular-weight organic substance with an important proportion of double bonds between the carbon atoms in the molecules in an aqueous solution of sulfuric acid. I n t h e normal state, sulfuric acid in solution does not react with the organic part of a mixture. The ionization potential of the C=C π-bond, which is less strong than the σ-bond [3, pp. 38-39], is approximately 11 eV [4, pp. 67-69].

Characterization and utilization of acid tar waste from crude benzol processing for environmental sustainability

“…The processing of fresh acid tar was said to be more difficult than that of acid tar from lagoon due to the high percentages of sulphuric acid [3]. In normal state sulphuric acid mixed with organics does not react with the organic part of the mixture [24]. This then makes the mixture difficult to deal with when fresh and yet once in lagoons reaction with air and water can take place thus reducing the acidity of the mixture.…”
