“…This result agrees with the findings of a study by Grieco and Baldi (2012) With respect to the effect of the presence of oxygen at high temperature, light hydrocarbons 217 yield decreased with the increase of λ (as shown in the last row in Table 1). In this way, emitted 218 hydrocarbons in the CWP series, when comparing λ=0 with λ=0.7, are reduced by more than 219 99.5%.…”

Combustion and pyrolysis runs at 850 ºC were carried out in a laboratory scale horizontal 10 reactor with different materials combining biomass and waste electrical and electronic 11 equipment (WEEE). Analyses are presented of the carbon oxides, light hydrocarbons, 12 polycyclic aromatic hydrocarbons (PAHs), polychlorinated benzenes (ClBzs), polychlorinated 13 phenols (ClPhs), polybrominated phenols (BrPhs), polychlorinated dibenzo-p-dioxins and 14 dibenzofurans (PCDD/Fs). Results showed that gas emissions were mainly composed of CO 15 and CO 2 ; the high level of CO found in the pyrolytic runs was easily transformed into CO 2 by 16 reaction with oxygen. The total amount of light hydrocarbons emitted was somewhat higher in 17 the samples containing WEEE, methane being the most abundant light hydrocarbon in all the 18 runs. However, the presence of WEEE reduced the emission of PAHs which clearly decreased 19 with the increase of the oxygen. The total amount of BrPhs increased in the decomposition of 20 the samples containing WEEE, reaching its maximum in pyrolysis runs. Emission of PCDD/Fs 21 was enhanced in pyrolytic conditions and they were easily destroyed in the presence of oxygen. 22 23

“…In term of char formation, the MSW pyrolysis produced more char, again caused by the paper and biomass (vegetable) in MSW. The same observation was made in other studies [35,123].…”

“…Another alternative for BSG reuse is thermochemical conversion, since the chemical composition of BSG indicates high energy potential to be exploited by recovery techniques [17]. Conventional gasification [18][19][20][21][22][23] and plasma gasification [24,25] are some of these thermochemical techniques with high potential to produce alternative fuels from both efficiency and economic perspectives [26]. It is considered an important route to convert biomass and waste materials to useful gas products that can be converted into energy via several technological options [27].…”

Experimental Analysis of Brewers’ Spent Grains Steam Gasification in an Allothermal Batch Reactor

In this work, brewers’ spent grains (BSG) were evaluated and studied in order to obtain a combustible gas by means of allothermal steam gasification. BSG were preprocessed in a rotary dryer and a pelletizer prior to gasification in an indirectly heated batch reactor. BSG characterization was conducted by means of proximate, ultimate, and thermogravimetric analysis, allowing us to conclude that BSG have characteristics comparable to those of regular lignocellulosic biomasses. Gasification tests were performed in an allothermal bench-scale batch reactor in order to determine the effect of temperature and steam-to-biomass ratio (S/B) in the produced gas. The produced gas was mainly composed of 22.8–30.2% H2, 15.1–22.3% CO, and 7.2–11.1% CH4, contributing to a heating value of 8.11–9.0 MJ/Nm3 with the higher values found for a low S/B ratio and for high temperatures. The performance of the process was assessed by evaluating the cold gas and carbon conversion efficiencies. These indicators were found to be in the ranges 47.0%–52.1% and 57.0%–62.7%, respectively. The main conclusion of this work is that the produced gas obtained from BSG steam gasification has sufficient quality to open other options to beer producers to use their own brewing wastes to satisfy their energy needs, allowing them to progress toward the circular economy concept.
