Summary:Wheat straw, as a model biomaterial, was evaluated as a support for Na sub(2)CO sub(3), which is a traditional solid sorbent precursor for flue-gas desulfurization. Sulfur dioxide removal experiments were carried out under atmospheric pressures using several samples of Na sub(2)CO sub(3)/biomass with different loadings. Results were compared with a reference sorbent on gamma -Al sub(2)O sub(3). Results showed that straw was a highly efficient support medium. Desulfurization activity was similar when dried leaves or fresh straw was used, and the desulfurization activity could be maintained over a wide temperature range.
