Recent advances in the gasification of waste plastics. A critical overview

Coke formation and deactivation during catalytic reforming of biomass and waste pyrolysis products: A review

“…The valorization of solid waste hydrocarbon and oxygenate materials (such as plastics and biomass) for H2 production may be performed by a two-stage in-line pyrolysisreforming process, whose recent interest lies, among other reasons, on the higher versatility of having two separated stages. Figure 5 shows the main reactor configurations designed for biomass and plastic wastes, mainly studied in bench and laboratory scale units [26,147].…”

“…Reactor configurations for pyrolysis and in-line catalytic steam reforming of plastic wastes and biomass: (a) two-stage fixed bed reactor, (b) fluidizedfixed bed reactor, (c) screw-kilnfixed bed reactor, (d) fluidized bed, entrained flow gasification and fixed bed reactor, and (e) spouted bedfluidized bed reactor. Adapted from[26,147].…”

“…Pyrolyse bij hogere temperaturen leidt tot steeds kleinere productmoleculen, zodat vergassing abstract gezien als een variant van pyrolyse kan worden beschouwd [Lopez et al 2018]. Door de hogere temperaturen zijn er nog duurdere reactor-bekledingsmaterialen nodig om corrosie te beperken [Ragaert et al2017].…”

“…Door de hogere temperaturen zijn er nog duurdere reactor-bekledingsmaterialen nodig om corrosie te beperken [Ragaert et al2017]. Een belangrijk aandachtspunt van vergassing is het beperken van de teervorming [Lopez et al 2018].…”

Flowsheet Modeling and Simulation of Biomass Steam Gasification for Hydrogen Production

“…The obtained mixture of gas can be used for polygeneration purposes mainly as thermal heat, power generation, or to produce different chemicals [18,28]. Syngas as a result of biomass gasification contains carbon monoxide gas, hydrogen gas, carbon dioxide gas, methane gas, traces of higher hydrocarbons such as ethane and ethene, water vapor, nitrogen (if air is used as an oxidizing agent for gasification), and various contaminants like ash, tar, small char particles, and oil [29][30][31][32].…”
