“…In the first stage, the air was injected into the pyrolysis zone using six nozzles. The air in this pyrolysis zone initiated the oxidation reaction between the air and carbon, called oxidative pyrolysis [20,[32][33][34][35]. The oxidation reaction released heat so that the pyrolysis properties changed from endothermal to exothermal.…”

The utilization of new and renewable energy sources explicitly based on biomass needs to be increased to reduce dependence on fossil fuels. One of the potential biomasses of plantation waste in Indonesia that can be utilized is oil palm plantation waste in the form of fronds and trunks that are converted with multi-stage downdraft gasification technology. This study aimed to conduct a technical analysis, economic analysis, investment risk analysis, social analysis, and an environmental impact assessment of power plants fueled by oil palm plantation waste. The method used was the upscaling of a prototype of a 10 kW power plant to 100 kW. The results showed that it was technically and economically feasible to apply. The economic indicators were a positive NPV of USD 48.846 with an IRR of 9.72% and a B/C ratio of 1.16. The risk analysis predicted a probability of an NPV 49.94% above the base case. The study of the social aspects suggested that the construction of power plants has a positive impact in the form of increased community income and the growth of new economic sectors that utilize electricity as a primary source. An analysis of the environmental effects is critical so that the impacts can be minimized. Overall, the construction of small-scale power plants in oil palm plantations is worth considering as long as it is carried out following the applicable regulations.

“…Several studies to evaluate the pyrolysis in BFB reactors were conducted [39][40][41][42][43][44][45]. These studies were performed with different materials, such as Amazon tucumã, grape, Quercus Acutissimain, PVC, PVC-wood, PVC-coal mixtures, Geodae-Uksae 1 (tetraploid M. sacchariflorus), kraft lignin and Laminaria japonica (brown algae).…”

The products obtained through thermal conversion of tyres can represent a solution for its disposal which has been considered an environmental problem. In the foundry industry two types of sand are generated: core sand (CS) and green sand (GS); CS is classified as hazardous waste. In this paper two kinds of industrial wastes were approached, in order to propose a solution through co-pyrolysis. The experiments were performed in a bubbling fluidized bed reactor. The oil, fuel gas and char obtained were characterized. The main components present in the oil were naphthalene and anthracene. Char morphology was assessed by Scanning Electron Microscopy, confirming the resin absence on its surface. Isothermal adsorption and desorption indicated that the char obtained from tyre pyrolysis with lower particles has higher superficial area (higher than 200 m2·g−1). The main compounds identified in fuel gas were hydrogen, carbon monoxide, carbon dioxide and hydrocarbons up to 5 carbons.

“…Kim investigated effects of oxygen (ER = 0.034 -0.539) on red oak bubbling fluidized bed pyrolysis (and a further study on combining alkaline and alkaline earth metal (AAEM)-passivation with autothermal pyrolysis to achieve 67% hydrolysable sugar yield [56]), suggesting vinylphenols and methoxyphenols are oxidized to aldehyde and ketone-containing compounds. Li et al, also investigating bubbling fluidized bed oxidative pyrolysis, achieved autothermal operation at 0.08g-O2/g-biomass, and similarly to Kim et al [71], observed high reactivity of acetic acid, hydroxylpropanone, LG, and methoxy/vinylphenols [66]. Additionally, Li quantified a ¼ -1 ⁄3 reduction in bio-oil energy density, possibly due to the high oxygen concentrations used (here, autothermal was defined as inclusive of parasitic heat loss from bed to surrounding environment) [66].…”

“…The existing oxidative pyrolysis studies provide a number of product composition references as a function of oxygen/air concentration for which the mechanistic framework can be compared with. When comparing findings of these studies, variability in experimental apparatus and definitions of terminology, autothermal operation for example, must be considered [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66]. Findings from this body of literature are summarized below.…”
