“…An average composition extracted from plasmix commodity related sheets drawn by household plastics recovery facility was reported and discussed in a previous work [33]. These sheets related to commodity were worked out together with product analysis data taken by literature [6,34] and the four most representative polymers were selected for the thermochemical and kinetic analysis. To understand the behavior of plastic waste during the pyrolysis and whether different compositions can lead to different thermal and kinetic behaviors three simulated and predefined quaternary sample mixtures were also tested.…”

“…Since plastics are mainly composed of hydrocarbons, thermal recycling of waste plastics to produce a synthesis gas (syngas) composed of a mixture of hydrogen and carbon monoxide represents a low cost feedstock for syngas production. There have been many reports on the production of hydrogen and synthesis gases from waste plastics by pyrolysis and gasification processes [4][5][6]. The addition of steam, catalyst and partial oxidation enhancing the production of gases through a catalytic steam reforming type process [7,8].…”

Abstract:Catalytic dry (CO2) reforming of waste plastics was carried out in a two stage, pyrolysis-catalytic reforming fixed bed reactor to optimise the production of syngas (H2 + CO). The effects of changing the process parameters of, catalyst preparation conditions, catalyst temperature, CO2 input rate and catalyst:plastic ratio were investigated. The plastics used was a mixture of plastics simulating that found in municipal solid waste and the catalyst used was Ni-Co-Al2O3. The results showed that changing each of the process conditions investigated, all significantly influenced syngas production. An increase of 17 % of syngas production was achieved from the experiment with the catalyst prepared by rising-pH technique compared to preparation via the impregnation method. The optimum syngas production of 148.6 mmolsyngas g -1 swp was attained at the catalytic dry reforming temperature of 800 °C and catalyst:plastic ratio of 0.5. The increase of CO2 input rate promoted a higher yield of syngas.

“…Pyrolysis and gasification of waste plastics is a promising route to produce high yields of a hydrogen-rich syngas. Pyrolysis of plastics produces low yields of hydrogen [6,7]. However, two-stage processing of waste plastics which combines thermal degradation of the plastic in a first stage pyrolysis step followed by gasification/reforming in a second stage, usually in the presence of catalysts generates high yields of hydrogen [8][9][10].…”

A range of process conditions, including the type of reactor, the reacting atmosphere and the presence of catalyst, and their influence on the production of syngas i.e. hydrogen and carbon monoxide, from the thermal processing of waste high density polyethylene (HDPE) has been investigated. Pyrolysis in the presence of nitrogen and in the presence of carbon dioxide, two-stage pyrolysis-steam reforming and carbon dioxide/catalysis process conditions were investigated in relation to gas composition and particularly hydrogen and carbon monoxide yield. The influence of addition of a Ni-Mg-Al catalyst in the second reactor was also investigated. It was found that a two-stage pyrolysis at 500 °C, followed by second stage reaction at 800 °C resulted in a significant increase in hydrogen production. With the addition of carbon dioxide, the two stage process also increased carbon monoxide yield in addition to hydrogen. Addition of steam into the second stage reactor with the carbon dioxide produced a further increase in hydrogen production. Also, the presence of a Ni-Mg-Al catalyst in the second reactor increased the amount of hydrogen and carbon monoxide produced.
