The intrinsic dependency between energy−water−food (EWF) resources is becoming more obvious with the growing demand for these resources. As such, it is necessary to develop assessment tools that adequately quantify the interlinkages between EWF systems and the surrounding environment and identify synergies and trade-offs that may exist. Meanwhile, biomass can be regarded as a potential replacement capable of lowering ecological footprint and resource scarcity in a variety of applications. Gasification is a favored method for biomass valorization, where the produced gas mixture is used to run power plants and generate clean energy. Furthermore, it can also be utilized in chemical industries to replace natural gas in the generation of ammonia and methanol. Assessing the strategy of various biomass utilization represents a rich research subject that can be tackled from an EWF Nexus standpoint, enabling quantifying the biomass utilization implications on the EWF systems. The economic feasibility of using biomass gasification feedstock for poly-generation of various products is examined in this study. Aspen Plus software is used to simulate three alternative gasification processes to generate the best characteristics for each application route. Furthermore, a sustainability index is used to assess the impact of each application route on EWF systems and to support financial decisions. The simulation results are incorporated into a linear programming optimization model to determine the best biomass utilization approaches considering economic feasibility and resource preservation. The optimization results demonstrate that steam gasification with syngas end-use for methanol production (95%) and power production (5%) are the most feasible biomass utilization routes, with an overall collective objective function of 997%, net water generation of 4.39, net food of zero, and net energy production of 1.78 × 10 −15 .

“…A portion of the syngas can be converted to hydrogen through steam reforming reactions, which can be used in fuel cells and other hydrogen-based energy technologies (Mann 1995 ). Additionally, syngas can also serve as a raw material for chemical production, including the synthesis of methanol, ammonia, ethylene, and other chemicals, which are widely used in the chemical industry (Alnouss et al 2021 ; Singh et al 2022 ; Zheng et al 2022 ). However, during pyrolysis/gasification, chlorine-containing products like plastic, fabric, and rubber products are predominantly converted to HCl with concentrations ranging from several to hundreds even thousand mg/m 3 (Pan et al 2021 ; Truc and Lee 2019 ) in syngas.…”

Unlocking high-performance HCl adsorption at elevated temperatures: the synthesis and characterization of robust Ca–Mg–Al mixed oxides

The presence of HCl and SO2 gas imposes limitations on syngas utilization obtained from household waste in a wide range of applications. The hydrotalcite-like compounds (HTLs) have been proved that could remove HCl efficiency. However, the research on impact of synthesis conditions of HTLs and SO2 on HCl removal was limited. In this study, a range of Ca–Mg–Al mixed oxide sorbents was synthesized by calcining HTLs, with variations in crystallization temperature, solution pH, and the Ca/Mg molar ratio. These sorbents were examined for their effectiveness in removing HCl at medium–high temperatures under diverse conditions. The adsorption performance of selected sorbents for the removal of HCl, SO2, and HCl-SO2 mixed gas at temperature of 350 °C, 450 °C, and 550 °C, respectively, was evaluated using thermogravimetric analysis (TGA). It was observed that the HTL synthesis parameters significantly influenced the HCl adsorption capacity of Ca–Mg–Al mixed oxides. Notably, HTLs synthesized at 60 °C, a solution pH of 10–11, and a Ca/Mg ratio of 4 exhibited superior crystallinity and optimal adsorption characteristics. For individual HCl and SO2 removal, temperature had a minor effect on HCl adsorption but significantly impacted SO2 adsorption rates. At temperatures above 550 °C, SO2 removal efficiency substantially decreased. When exposed to a mixed gas, the Ca–Mg–Al mixed oxides could efficiently remove both HCl and SO2 at temperatures below 550 °C, with HCl dominating the adsorption process at higher temperatures. This dual-action capability is attributed to several mechanisms through which HTL sorbents interacted with HCl, including pore filling, ion exchange, and cation exchange. Initially, HCl absorbed onto specific sites created by water and CO2 removal due to the surface’s polarity. Subsequently, HCl reacted with CaCO3 and CaO formed during HTL decomposition.
