TL;DR: In this article, a review of the main waste plastics valorization routes to produce syngas and H2 is presented, covering different gasification strategies and other novel alternative processes, such as pyrolysis and in-line catalytic steam reforming.

TL;DR: In this paper, a review of the progress in gasification techniques and key generation pathways for biofuel production, process design and integration and socio-environmental impacts of biofuel generation are discussed, with the goal of investigating gasification-to-biofuels credentials as a sustainable and eco-friendly technology.

TL;DR: In this paper, a review of catalytic steam reforming of tar derived from biomass, tar formation, tar properties and catalytic reaction mechanism are also introduced, and prospects and challenges are summarized.

TL;DR: A critical review about the fates of main chemical elements (C, H, O, N, P, Cl, S, and metals) in biomass during its pyrolysis is provided and the research advances about the emission, transformation, and distribution are overviewed.

TL;DR: In this paper, the authors reviewed the literatures pertaining to tar reduction or destruction methods during biomass gasification/pyrolysis and classified them into five main groups: mechanism methods, self-modification, thermal cracking, catalyst cracking and plasma methods.

TL;DR: The pyrolytic properties of biomass are controlled by the chemical composition of its major components, namely cellulose, hemicelluloses and lignin and their minor components including extractives and inorganic materials as mentioned in this paper.

TL;DR: In this paper, a review of the recent studies in tar treatment from biomass gasification is presented, where the new technologies with their strengths and weaknesses in term of tar reduction are discussed.

TL;DR: In this article, a detailed overview on tar chemical and physical properties, reforming mechanism and reaction kinetic model are summarized in a detail overview on coal-to-tar conversion process is presented.
