本刊讯(王震报道)近日,国家发改委公布了第二批《国家重点推广的低碳技术目录》,泉林纸业“秸秆清洁制浆及其废液肥料资源化利用技术”成功入选,是其中两项碳汇类技术之一。“秸秆清洁制浆及其废液肥料资源化利用技术”是由泉林纸业自主研发,主要是针对秸秆纤维特点,通过锤式备料、亚铵法置换蒸煮、机械疏解-氧脱木素等工艺,实现木素高效脱除、降低黑液黏度并提高黑液提取率,形成适于秸秆的本色纸浆及纸制品制造技术;同时,提取秸秆木质素、微量元素等生产黄腐酸有肥料,实现秸秆全效利用和秸秆科学还田。该技术含有14项
Recently, the NDRC released the second batch of “Catalog of Low-carbon Technologies Key to Promote by the State,” and Quanlin Paper’s “Utilization Technology of Straw Cleaning Pulp and Waste Liquid Fertilizer” Successfully Selected, is one of two carbon sink technology. “Straw cleaning pulping and its waste liquid fertilizer utilization technology ” is independently developed by the spring forest paper industry, mainly for the characteristics of straw fiber, by hammer preparation, iminium substitution displacement cooking, mechanical ease - oxygen delignification And other processes to achieve efficient removal of lignin to reduce the viscosity of black liquor and improve the black liquor extraction rate, the formation of suitable natural straw pulp and paper products manufacturing technology; the same time, the extraction of straw lignin, trace elements such as the production of fulvic acid Fertilizer, to achieve the full utilization of straw and straw science to the field. This technology contains 14 items
