Summary: | The method discloses a method for preparing SiO2 by reusing biomass resources. The method comprises the following steps: (1) removing metal elements: placing biomass materials in a dilute acid solution to be extracted, and then carrying out filtration and separation to obtain biomass and water extract; (2) preparing SiO2: rinsing and drying the biomass and then carrying out complete combustion, thus obtaining a noncrystalline SiO2 product. The method disclosed by the invention can efficiently remove the metal elements of the biomass resources of chaff, straw and the like, and the high-purity noncrystalline SiO2 is prepared, so that efficient and safe utilization of the biomass resources is realized.
本发明公开了种生物质资源再利用制备SiO的方法,包括以下步骤:(1)金属元素去除:将生物质材料置于稀酸溶液中浸提,然后过滤分离,得到生物质和浸提液;(2)SiO的制备:将生物质进行漂洗、烘干,然后完全燃烧,得到非结晶的SiO产品。本发明的方法可高效去除谷壳、秸秆类等生物质资源的金属元素,制备出高纯度非结晶SiO,实现生物质资源的高效安全利用。 |
