“…Li et al [18] co-gasified polyethylene and pinewood under CO 2 atmosphere, in which a positive synergistic effect between polyethylene and pinewood was found with respect to energy yield. In addition to cogasification of biomass with plastics, a mixture of coal and plastics has been investigated [19][20][21] . In the real application scenario, it would be interesting to see how the replacement of woody biomass with a novel biomass waste stream, such as, potato peel, would affect the chemistry and the product of the gasification process.…”

“…The utilization of carbon dioxide as a gasifying medium is promising since tar and char could be converted into permanent gas, improving the gasification process performance [35][36][37]. However, the utilization of carbon dioxide establishes an intensive endothermic process, which requires a specific reactor design or the addition of oxygen to promote oxidation reactions that provide the necessary thermal energy to support the exothermic reactions of the gasification process.…”

In this study, the effect of gasifying agent and bed material on the performance of the co-gasification of a mixture of coal, plastic waste, and wood was investigated. The experimental runs were carried out in a lab-scale bubbling fluidized bed reactor utilizing air, oxygen-enriched air, a mixture of air and steam, and a mixture of oxygen and carbon dioxide as reactant gases, while silica sand, olivine, and a mixture of olivine and dolomite as bed materials were used. The results indicated that both gasifying agent and bed material strongly affect the gas composition and, as a consequence, the process performance. In particular, the test with oxygen-enriched air and silica sand provided a producer gas with the highest heating value (9.32 MJ/Nm3), while the best performance in terms of gas yield (2.98 Nm3/kg) and tar reduction (−94.5%) was obtained by utilizing the air/steam mixture and olivine. As regards tar composition, it was observed that the most abundant and recalcitrant tar substance groups are naphthalenes and PAHs. On the other hand, phenols and furans appear to be the most sensitive groups to the effect of gasifying agent and bed material.

In the present study, kitchen waste is chosen as a solid feed for producing high‐caloric valuable syngas using CO2 as a gasifying agent. Dried kitchen waste is gasified in a spouted fluidized bed reactor for syngas production. In the process, along with syngas, a significant quantity of oil (48 wt.%) and solid char residue is obtained during pyrolysis. Further, the spouted bed process is simulated in ASPEN PLUS using various reactor modules and the calculated results is validated with the experimental data. A model using the combination of continuous stirred tank reactor (CSTR) and plug flow reactor (PFR) with recycling of gas and char fits the behaviour of spouted bed. Further, the experimental investigation of fixed and spouted bed gasification of kitchen showed that the calorific value of syngas obtained during gasification is 10.45 MJ/nm3 with 30.00 vol.% CO and 24.00 vol.% H2. Further, the effect of process parameters such as pressure, temperature, spouting gas flow rate, and feed rate of kitchen waste on overall syngas composition is evaluated using ASPEN PLUS software.
