摘要：Water hyacinth has attracted extensive attention due to its capability to capture carbon dioxide and remove excess nutrients and toxic metal ions; however, its exuberant growth also leads to environmental problems. In this study, water hyacinth was introduced to prepare bioslurry fuels with coal in the entrained-flow gasification process. Water hyacinth was modified with the addition of Fe-2(SO4)(3). Rheological properties and ash fusion temperatures of the modified-hyacinth-coal slurry (MHCS) were investigated. MHCS with solids loading of 60.0 wt % was prepared by adding 19.2 g of modified water hyacinth to 100 g of coal that showed more stability and shear-thinning behavior (thixotropy) than those of coal-water slurry. The ash fusion temperatures of most water hyacinth-coal blends are lower than those of coal and water hyacinth. The modified water hyacinth could further reduce the ash fusion temperature of coal because low-melting eutectic mixtures were formed.
