Description

The purpose of this research is the industrialization of hydrogen production using a commercial microwave oven by generating plasma in waste oil. N-dodecane, engine oil and cooking oil were used as a liquid. N-dodecane can be circulated in the experimental device to assume continuous production of hydrogen. The gas production rate was measured, the content of the produced gas was analyzed. The energy efficiency which was expressed as the ratio of the consumed power for the chemical reaction to the microwave power was calculated. The energy efficiency increased with decrease of the microwave power, and reached 14% at the maximum. To improve the energy efficiency the reaction vessel was decompressed. The gas production rate became approximately 2 times larger and the ratio of hydrogen in the produced gas.
