abstract = {Considering the pressing challenges of supply security and
climate change, advanced processes to produce electricity
and biofuels from biomass have to be developed. Biomass
gasification is a very promising technology, but there is a
lack of comprehensive reviews, specifically on the
technologies for hydrogen chloride hot gas cleanup, which
are necessary in order to work at the same temperature and
respect the limits of advanced downstream components. In
this review, the Cl content of the main biomasses in Europe
is given, and data on syngas content and the tolerance of
downstream equipment are highlighted. Hot gas cleaning
technologies, which have the advantage of improved thermal
efficiency are reviewed, analyzing the thermodynamic and
primary and secondary methods. This review identifies NaAlO2
and Na2CO3 within 450–550 °C as the most effective
sorbents, which are able to reduce the concentration of HCl
below 1 ppm. Nevertheless, H2S cannot be simultaneously
removed and has to be removed first, because it reduces the
HCl adsorption sorbent capacity. V},
