Abstract
Adsorption on low cost minerals is thought to be an interesting technology to reduce alkali concentration in syngas generated by agro-based biomass gasification. In this work, six samples of natural mineral sorbents were exposed to vapor of NaCl under dry and humid environments, at total pressures of 5 mbar and 1 bar, and at temperatures of 700, 775 and 850 °C in order to evaluate their uptake capacities by using thermogravimetry coupled with mass spectrometry. While under dry conditions physisorption seems to be the dominant mechanism, under humid conditions chemisorption contributes to a significant rise in the uptake for most of the cases. Bauxite, palygorskite and natural zeolite presented the best uptakes on average under both dry and humid conditions. Sorbents containing moderate to high contents of Al seem to be suitable materials for alkali/vapor removal.
