“…As already discussed in Section 2, signicant tar reduction can already be achieved through innovative gasier designs and operations. This is an active research area with low tar formation being reported from certain large capacity gasiers such as conventional uidized beds, [143][144][145] dual uidized beds, [146][147][148] plasma gasiers 24 and the novel fountain enhanced conical spouted gasier. 149 In some cases, the type of gasifying agent used during the gasication process can also inuence the formation and yield of tar.…”

“…Regenerations based on air, O 2 , O 3 , NO x , and H 2 are exothermic while regenerations based on CO 2 and H 2 O are endothermic. 148 Regeneration techniques are oxidation (air, ozone and oxynitride), gasification (carbon dioxide and water steam), and hydrogenation (hydrogen). Oxidation based on air or oxygen (O 2 and O 3 ) is the most common technique to regenerate catalysts.…”

“…Moreover, the large-scale demonstration of DFB plants [7] and studies on their implementation in existing industries [17] have been executed. Furthermore, the necessary gas cleaning steps following the gasification process have been successfully demonstrated [18,19]. The experimental validation and demonstration of the methanation unit [6,[20][21][22] and FT synthesis [23][24][25][26][27] have also been conducted.…”

The production of sustainable, biomass-based synthetic natural gas (SNG) and Fischer–Tropsch (FT) diesel can contribute significantly to climate neutrality. This work aims to determine the commercial-scale production costs and CO2 footprint of biomass-based SNG and FT diesel to find suitable integration scenarios for both products in the Austrian energy system. Based on the simulation results, either 65 MW SNG and 14.2 MW district heat, or 36.6 MW FT diesel, 17.6 MW FT naphtha, and 22.8 MW district heat can be produced from 100 MW biomass. The production costs with taxes for wood-based SNG are 70–91 EUR /MWh and for FT diesel they are 1.31–1.89 EUR /L, depending on whether pre-crisis or crisis times are considered, which are in the range of fossil market prices. The CO2 footprint of both products is 90% lower than that of their fossil counterparts. Finally, suitable integration scenarios for SNG and FT diesel in the Austrian energy system were determined. For SNG, use within the energy sector for covering electricity peak loads or use in the industry sector for providing high-temperature heat were identified as the most promising scenarios. In the case of FT diesel, its use in the heavy-duty traffic sector seems most suitable.

“…Among them, adsorption has been widely used to remove VOCs from the air [22][23][24]. The advantages of adsorption are included low operational cost, easy accessibility of used materials, sometimes reusability, and high removal efficiency [25]. In particular, the performance of adsorption can easily increase the efficiency with adsorbate structure and properties [26].…”

The main target of this study was to eliminate gas-phase toluene with activated carbon from indoor air. The activated carbons were prepared from Robinia pseudoacacia L. biomass under different conditions. The change in surface functional groups of the activated carbon biomass raw material produced by pyrolysis in the absence of oxygen at 500-900 °C and activation by potassium hydroxide (KOH). The highest surface area of 1271.3 m 2 /g gives reason for its external porous surface. The surface porosity and the graphite properties of the prepared KNxACs were detected by scanning electron microscope (SEM). The amount of adsorbed toluene (C7H8) was determined using a gas chromatograph-mass spectrometry with a thermal desorber system (TD-GC-MS) on the KNxAC surface. The toluene adsorption capacity was reached 111 mg/g at 25 °C and 1000 ppm. As a result, the study revealed that the prepared KN24AC from the Robinia pseudoacacia L. biomass has the best adsorption capacity of gasphase toluene from indoor air.
