“…One of the concerns associated with gasification is the continuous build‐up of condensable (high‐molecular‐weight) organic compounds (tar), that, besides their environmental impact, can cause problems to the process equipment and to the devices for end‐use applications (such as gas engines and turbines). The production of tar, strictly correlated to the fuel structure and composition, and to the gasifier process conditions, is unavoidably associated with an increase of operating and maintenance plant costs, together with process efficiency loss 22,23 …”

“…The production of tar, strictly correlated to the fuel structure and composition, and to the gasifier process conditions, is unavoidably associated with an increase of operating and maintenance plant costs, together with process efficiency loss. 22,23 The main tar compounds usually found in syn-gas are (apart from benzene) toluene, naphthalene, phenolic compounds and a plethora of other polycyclic aromatic hydrocarbons with or without heteroatoms such as S, N, O. 24 Therefore, tar compounds are not inert.…”

The sustainable fulfilment of world energy demand should be based on the diversification of the energetic portfolio and, at the same time, on the decrease of the use of fossil fuels in favour of renewable energy sources. This perspective review article focuses its attention on a particular source of renewable energy, i.e. biomass. As non‐fossil materials of natural origin, biomasses are formed by storing, in the noble and stable form of chemical bonds, solar energy. Gasification has been here chosen as biomass thermoconversion route: general concepts and history, chemical reactions and uses of syn‐gas, and the role of tar, are addressed. Fluidised beds are discussed as reactors to carry out biomass gasification, also considering that a new approach based on dual interconnected fluidised bed schemes can realise the concept of sorption‐enhanced gasification (to increase H2 productivity). Syn‐gas and tar characteristics are presented and, finally, an original case study concerning the fluidised bed gasification of civil and industrial sludges is presented. © 2023 The Authors.
