This research focused on the application of integrated biorefinery concept to Kash (Saccharum spontaneum). This was carried out by 1) pre-extraction using potassium hydroxide (KOH) in order to remove silica, some of the lignin and hemicelluloses, 2) further delignification by KOH at varying KOH charges; both stages were operated under 100 °C. The pre-extraction removed 75.6 % lignin, 40.8 % pentosans and 75 % silica from the Kash. With the second KOH delignification under optimum conditions (12 % alkali, 120 min, 90 °C), a pulp yield of 49.7 % (on Kash) with kappa numbers 30.3 was obtained. KOH Kash pulp was bleached to 86.3 % brightness in D₀(EP)D₁ bleaching sequence with good papermaking properties. The KOH spent liquor, which contains silica and dissolved organics, was further investigated for value-added utilization. The dissolved biomass in KOH spent liquor improved soil properties, thus increasing Kolmi sag production in pot experiment. The dissolved lignin in KOH spent liquor was isolated and characterized with lower methoxyl content, higher phenolic hydroxyl content and lower molecular weight, consequently it can replace up to 40 % phenol in phenol formaldehyde resin preparation.

这项研究的重点是将综合生物精炼概念应用于喀什（Saccharum spontaneum）。这是通过以下步骤进行的：1）使用氢氧化钾（KOH）进行预萃取以除去二氧化硅，部分木质素和半纤维素； 2）在不同的KOH电荷下通过KOH进一步脱木素；两个阶段均在100°C下运行。预萃取从Kash中除去了75.6％的木质素，40.8％的戊聚糖和75％的二氧化硅。在最佳条件下（12％碱，120分钟，90°C）进行第二次KOH脱木素，纸浆收率为49.7％（按Kash计），kappa值为30.3。在D ₀（EP）D ₁中将KOH Kash浆漂白至86.3％的亮度具有良好造纸性能的漂白顺序。进一步研究了含有二氧化硅和溶解的有机物的KOH废液的增值利用。溶解在KOH废液中的生物质改善了土壤特性，从而增加了盆栽试验的Kolmi流挂产量。分离出溶解在KOH废液中的木质素，并表征为较低的甲氧基含量，较高的酚羟基含量和较低的分子量，因此它可以代替酚醛树脂制备中的40％的酚。
