Production of high quality syngas from argon/water plasma gasification of biomass and waste

Net emission coefficient for CO–H2 thermal plasmas with the consideration of molecular systems

“…Indeed, for the regions with low temperature (approximately o4 kK), the composition is dominated by the polyatomic species, mainly CO 2 , CH 4 and H 2 O in the current case. The total radiation power emitted locally could be in such cases fully caused by the rovibrational lines of the polyatomic molecules and therefore, they must be taken into account.…”

“…Plasma gasification stars to be an industrial process for syngas production but a lot of research works are still in development to improve the process. For instance, the plasma process can be based on alcohol or wood treatment [1], biomass gasification [2][3][4] or waste valorization [5]. In general an electric arc creating a thermal plasma at rather high temperature (around 10,000 K or more) is used in a first step of the process (non-equilibrium discharges can also be used [1]) but the final chemical reactions should occur in a plasma at intermediate temperature (lower than 5000 K) where the molecules are produced.…”

A review on plasma gasification for solid waste disposal

“…Hlina et al [11] investigated the gasification of woody biomass, plastics and oils by a 110 kW power plasma system. The gasification of wood had the best efficiency.…”

A critical review on biomass gasification, co-gasification, and their environmental assessments

“…The results showed that, assuming zero cost for waste refuse feedstock, the products (i.e., F-T diesel and kerosene) would be cost-competitive with similar products obtained from a petroleum process. Hlina et al (2014) experimentally studied a plasma torch with DC electric for high temperature (18000 °C) plasma gasification of wood, waste plastics, and pyrolysis oil. The ratio of net arc power to the mass flow rate of plasma was drastically higher than standard regime of arc, although …”
