“…MSW can be converted into higher value gaseous or liquid fuels such as syngas or alcohols [11] and the RDF through three routes, which is described by Figures 2 and 3. These include gasification to produce syngas, pyrolysis to produce bio-oil, or biomass liquefaction and hydrolysis to produce sugars [5].…”

“…Beyond syngas, biofuels and high value chemicals derived from biomass are also of significant interest to scientists, engineers, and policymakers [15]. Among liquid fuels, ethanol production from cellulosic biomass is the most developed technology [11] with new fuel molecules including methanol [17,18], butanol [19,20], longer-chain alcohols [21,22], furan-based molecules [23,24], and bio-derived synthetic hydrocarbons [11] being investigated.…”

“…The typical Ni-based catalysts used in methane reforming have good conversion performance, but they degrade via several paths including sintering, coke formation, and poisoning. Therefore, there is ongoing research focused on designing and developing new, more durable catalysts including for example nanomaterials/nanocomposites that have high activity, durability, and are economical, which are necessary to overcome the disadvantages of waste-derived biofuels via DR using Ni-based catalysts [11].…”

“…Reheating the exhaust is economically prohibitive. Furthermore, other poisons exist in the MSW flue gas that can inhibit V-based SCR catalyst performance such as alkali metals [11,12]. Therefore, current challenges would be developing lower-temperature SCR catalysts and/or catalysts that are insensitive to SO2 or alkali metal poisoning.…”

Abstract:The present review paper highlights recent progress in the processing of potential municipal solid waste (MSW) derived fuels. These wastes come from the sieved fraction (∅ < 40 mm), which, after sorting, can differ in biodegradable fraction content ranging from 5-60%. The fuels obtained from these wastes possess volumetric energy densities in the range of 15.6-26.8 MJL −1 and are composed mainly of methanol, ethanol, butanol, and carboxylic acids. Although these waste streams are a cheap and abundant source (and decrease the fraction going to landfills), syngas produced from MSW contains various impurities such as organic compounds, nitrogen oxides, sulfur, and chlorine components. These limit its use for advanced electricity generation especially for heat and power generation units based on high temperature fuel cells such as solid oxide fuel cells (SOFC) or molten carbonate fuel cells (MCFC). In this paper, we review recent research developments in the continuous MSW processing for syngas production specifically concentrating on dry reforming and the catalytic sorbent effects on effluent and process efficiency. A particular emphasis is placed on waste derived biofuels, which are currently a primary candidate for a sustainable biofuel of tomorrow, catalysts/catalytic sorbents with decreased amounts of noble metals, their long term activity, and poison resistance, and novel nano-sorbent materials. In this review, future prospects for waste to fuels or chemicals and the needed research to further process technologies are discussed.

The performance of direct carbon solid oxide fuel cells (DC‐SOFCs) is limited by the slow carbon gasification kinetics at operating temperatures. To address this limitation, a carbon fuel loaded with Ba catalyst is developed for DC‐SOFCs to improve the electrochemical performance in this study. Ba is loaded on activated carbon in the form of BaCO3 by the wet agglomeration technique. The effect of the Ba catalyst with various contents on the electrochemical performance in single cells and fuel utilization of DC‐SOFCs are examined. Experimental results show that the optimized Ba content is 5 wt% and the DC‐SOFC with this Ba‐loaded activated carbon fuel gives the best output with a maximum power density of 328.4 mW cm−2 at 850 °C. Furthermore, the DC‐SOFC fueled by 5 wt% Ba‐loaded activated carbon operates steadily for 28.76 h with the fuel utilization of 16.0%, which is also superior to many other cells. The enhancement of cell performance suggests that Ba is an effective catalyst to the Boudouard reaction, and the catalytic mechanism is also discussed in detail.

Blending biomass feedstock is a promising approach to mitigate supply chain risks that are common challenges for large‐scale biomass utilization. Understanding the potential environmental benefits of biofuels produced from blended biomass and identifying driving parameters are critical for the supply chain design. Herein, a cradle‐to‐gate life cycle analysis model for fast pyrolysis biorefineries converting blended feedstocks (pine residues and switchgrass) with traditional centralized and alternative decentralized preprocessing sites, so‐called depots, is explained. Different scenarios are developed to investigate the impacts of parameters such as feedstock blending ratios, biorefinery and depot capacities, preprocessing technologies, and allocation methods. The life‐cycle energy consumption and global warming potential (GWP) of biofuel production with depots vary between 0.7–1.1 MJ MJ−1 and 43.2–76.6 g CO2 eq. MJ−1, respectively. The results are driven by biorefinery processes and depot preprocesses. A decentralized design reduces the energy consumption of the biorefinery but increases the overall life‐cycle energy and GWP. Such increases can be significantly mitigated by increasing switchgrass content as the energy consumption at the depot is driven largely by the higher moisture content of pine feedstocks. Allocation methods also have a large impact on the results but do not change the major trends and overall conclusions.
