Abstract

In this work, a low-temperature plasma initiated in liquid media between electrodes has been shown to be able to decompose hydrogen containing organic molecules resulting in obtaining gaseous products with volume part of hydrogen higher than 90%. As feedstocks, organic compounds (alcohols, esters) as well as direct water-hydrogen emulsions obtained by ultrasonic treatment were used. It was shown that hydrogen productivity from emulsions is not less than that from individual substances. Optical spectroscopy was used to confirm the formation of atomic hydrogen in the reactions of plasma decomposition of liquids. The measurement of the amount of the gas mixture formed during the decomposition of organic liquids shows that the output is highly dependent on the discharge current, and also on the volume of the discharge, which can vary depending on the distance between the electrodes in the reaction chamber.
