“…However, metal sintering and oxidation in tar steam reforming should be considered. In recent years, char catalysts (i.e., coal char and biomass char) with carbon-neutral properties were widely investigated and showed excellent anti-coking activity in biomass tar reforming. − In this case, introducing char-derived catalyst may be helpful to resist coke formation, but there are few literatures detecting carbon deposition because of indistinguishable carbon carriers and coke.…”

Value-added chemicals originating from biomass gasification in the presence of advanced catalysts have proved to be promising for valuable chemical generation via deep processing. In the issues of biomass gasification, the deactivation of heterogeneous catalysts is a common problem during the reforming of biomass tar and derived model compounds. Herein, deactivation pathways and regeneration methods are crucial to understand the production of value-added chemicals and guide the design of heterogeneous catalysts during biomass gasification. Unfortunately, to the best of our knowledge, there still has been no review to conclude the recent advances in catalyst deactivation and regeneration. To address the issues mentioned above, in this perspective, common catalysts for biomass tar reforming are first discussed. Then, key features and considerations of catalyst deactivation especially catalyst poisoning and carbon deposition are comprehensively reviewed based on the latest literature reports. Finally, the possible methods of tar elimination, metallic site recovery, and catalyst optimization are reviewed. Meanwhile, the future perspectives toward catalyst design, deactivation, and regeneration in tar reforming are shared. Through this perspective, the existing challenges, solutions, and future strategies in tar reforming or other gas−solid reactions are expected to be made clearer for following research on practical applications on an industrial scale.

“…In a next step, naphthalene was used as a model tar molecule and Corona plasma-aided thermal cracking was demonstrated successfully for its removal at 800 • C [95]. This study was cited with respect to tar generation and conversion kinetics [96], regarding the required high temperatures of 1100 • C which represent a disadvantage compared to catalytic reforming [97], and as an example for thermal tar cracking [98]. Finally, two CaO-rich catalysts doped with Sr were synthesized from mussel shells and successfully tested for tar cracking in the syngas [99].…”

The EU Training Network for Resource Recovery through Enhanced Landfill Mining—A Review

2021

The “European Union Training Network for Resource Recovery Through Enhanced Landfill Mining (NEW-MINE)” was a European research project conducted between 2016 and 2020 to investigate the exploration of and resource recovery from landfills as well as the processing of the excavated waste and the valorization of the obtained waste fractions using thermochemical processes. This project yielded more than 40 publications ranging from geophysics via mechanical process engineering to ceramics, which have not yet been discussed coherently in a review publication. This article summarizes and links the NEW-MINE publications and discusses their practical applicability in waste management systems. Within the NEW-MINE project in a first step concentrates of specific materials (e.g., metals, combustibles, inert materials) were produced which might be used as secondary raw materials. In a second step, recycled products (e.g., inorganic polymers, functional glass-ceramics) were produced from these concentrates at the lab scale. However, even if secondary raw materials or recycled products could be produced at a large scale, it remains unclear if they can compete with primary raw materials or products from primary raw materials. Given the ambitions of transition towards a more circular economy, economic incentives are required to make secondary raw materials or recycled products from enhanced landfill mining (ELFM) competitive in the market.

“…However, other non-expensive heteroatoms could serve as catalytic promoters for carbon supports. In this sense, Lu et al studied tar model compounds for steam reforming using char-supported nickel catalysts [40]. The authors found that the addition of P into the catalyst resulted in a better catalytic performance, which was attributed to the presence of acid sites together with an enhancement in the Ni dispersion.…”
