Production of syngas from agricultural wastes by plasma-chemical method

Abstract

A promising technology for utilization of agricultural waste is chemical plasma technology based on hightemperature plasma-chemical effects and the decomposition of hydrocarbon products to produce synthesis gas. Emulsified mixture of cow dung and water was placed into the reactor for producing synthesis gas. On entering the emulsion is exposed to flame of a gas burner with a combustion temperature of two thousand degrees. The plasma-chemical reactor was regularly tested in different modes to find the best mode for the production of synthesis gas and its composition. The stability of the voltage at the output of the electric generator was monitored at various loads. As a result, a stable operation of the gas generator was achieved. Chemical characteristics of syngas obtained appeared to be high: gas was pure and without dust, CO2 content was low, but content of hydrogen and CO was high, namely 31.62 % and 37.28, respectively. Gas quality was checked by visual observation of the burner flame and the temperature of the burning gas using an infrared pyrometer. The stability of the flame and the stability of the temperature of combustion characterize the quality of synthesis gas. It is shown experimentally that the plasma-chemical treatment of hydrocarbons and agricultural wastes is a highly effective method for producing synthesis gas.
