    • In the process disclosed herein, siliceous plant matter is steeped in water, soaked in an aqueous solution containing a solute which solubilizes inorganic oxides, soaked in an aqueous solution containing an oxidizing solute, rinsed, dried and thermally pyrolyzed to produce amorphous silica with of low carbon content, low water content, low inorganic impurity content and is of high porosity. Practice of the invention yields usable energy, does not produce carbonization of the atmosphere and is of lower nitrogen oxide and sulphur emission than currently used processes. Lignin, hemicellulose and cellulose derived sugars may be recovered from the steep or soak water. By varying steps of the process herein disclosed, the carbon content, inorganic impurities and porosity of the resulting amorphous silica may be selectively controlled.
    • 在游离缺失的过程中盘,硅质物质在水中的植物浸泡,浸泡在以wässrige溶液含溶质哪个溶解无机氧化物,浸泡在以wässrige溶液含氧化溶质,漂洗,干燥和热热解以产生具有的低的无定形二氧化硅 碳含量,低的水含量,低无机杂质含量和高的孔隙率。 本发明的实践产生可用能量,不会产生大气的碳化和较低的氮氧化物和硫的排放比目前使用的过程。 木质素,半纤维素和纤维素衍生的糖可以从陡峭或浸泡水回收。 通过改变在游离缺失光盘的过程的步骤中,碳含量,无机杂质和孔隙率将所得的无定形二氧化硅可以被选择性地控制。
