Electric arc gasification of pyrolysis oil with the production of hydrogen-enriched synthesis gas and carbon nanomaterial

Environmentally friendly conversion of waste and energy carriers into useful and energy-efficient products is one of the forefront areas worldwide. In this paper, we propose a new method for obtaining carbon nanomaterial and hydrogen-enriched synthesis gas by electric arc gasification of pyrolysis oil in an open-air environment without pollutant emissions. As initial samples, we used petroleum (as reference sample) and pyrolysis oil - liquid py-rolysis products of wood waste (pine sawdust), waste tires and oil sludge recycling. The choice of materials was caused by the search for new approaches to waste conversion, which will allow to obtain environmentally friendly energy and to reduce carbon footprint of various production cycles. The synthesis gas formed by electric arc gasification contained hydrogen in an amount exceeding 50 vol%. The carbon material was represented by nanosized objects with a graphite-like structure and characteristics similar to carbon black, which acted as a solid-phase product.

Automated summary

This paper proposes a new method for obtaining carbon nanomaterial and hydrogen-enriched synthesis gas through electric arc gasification of pyrolysis oil in an open-air environment without pollutant emissions. The choice of materials and the formation of synthesis gas with high hydrogen content contribute to environmentally friendly energy production and reduction of carbon footprint.
