Gasification characteristics of waste plastics (SRF) in a bubbling fluidized bed: Use of activated carbon and olivine for tar removal and the effect of steam/carbon ratio

Hydrogen-rich gas production from disposable COVID-19 mask by steam gasification

“…Dolomite and AC substantially increased the concentration of H 2 in the product gas. Han et al [27] , [28] conducted steam gasification experiments for solid refuse fuel (SRF) in various S/C ratio ranges using the same apparatus as used in this study, and air gasification was studied using various temperature ranges. It was found that the steam/carbon(S/C) ratio is the most effective in terms of hydrogen generation and tar removal at 1.5, and the calorific value of product gas and CCE were the highest at 800 ℃ between 600-800 ℃.…”

“…In this study, a 1 kg/h lab-scale (diameter: 0.114 m, height: 1 m) externally heated bubbling fluidized bed gasifier was used to investigate the characteristics of waste mask steam gasification. Steam gasification experiments were carried out at a steam/carbon ratio (S/C) of 1.5, temperature of 800 °C, and a feeding rate of 4.09-4.66 g/min based on previous study [27] .…”

Physico‐chemical characterization of Residual Household Waste for energy recovery in insular territories: Case study of Reunion Island

“…These analyses were carried out on the undried raw samples (raw basis) as well as on the dried samples (dry basis). The Exhibit 6 gives the parameters of some local RHW (ILEVA, 2015) and SRF (Vonk et al., 2018; Han et al., 2022) found in the literature.…”

“…Current R&D work on waste-to-energy is mainly focused on processes using biomass (Hatik and Gatina, 2017) or "mono-waste" such as tires, wood, plastics, or even rigorously prepared waste such as SRF (Vonk et al, 2018;Han et al, 2022) , 2015). In France, the regulation currently concerns only four pollutants on SRF (ADEME, 2015): chlorine content must be less than 15,000 mg/kg on dry product, bromine content must be less than 15,000 mg/kg, the total halogen content must be less than 20,000 mg/kg and the mercury content must be less than 3 mg/kg on dry product.…”

SRF is mainly composed of wood, plastic, and cardboard/paper in variable quantities and is used in furnaces and incineration plants.…”
