Method for preparing biomass retarder from agricultural wastes, and application of biomass retarder
The invention provides a method for preparing a biomass retarder from agricultural wastes, and application of the biomass retarder. The method comprises the following steps: 1) performing high-energy ball milling on the agricultural wastes to obtain agricultural waste powder; 2) carrying out directional wet degradation on the agricultural wastes obtained in the step 1) through a metal-loaded solid acid catalyst; and 3) carrying out solid-liquid separation on the wet decomposition product to obtain the liquid biomass retarder, and recovering the catalyst at the same time. The biomass retarder prepared by the invention is good in water solubility, green, degradable, excellent in performance and low in cost, the whole production process is low in energy consumption and small in pollution, and the biomass retarder can be used as a cement retarder in cement admixtures. The invention provides a feasible technical path for high-value utilization of agricultural wastes and application of the agricultural wastes in the field of construction industry.
本发明提供了一种利用农业废弃物制备生物质缓凝剂的方法及其应用，方法包括：1)将农业废弃物进行高能球磨，得到农业废弃物粉末；2)通过负载有金属的固体酸催化剂对步骤1)中得到的农业废弃物进行定向湿解；3)将湿解产物固液分离，得到液体生物质缓凝剂，同时对催化剂进行回收。本发明制备的生物质缓凝剂水溶性好、绿色可降解、性能佳、成本低廉，整体生产工艺能耗低、污染小，在水泥外加剂中可用作水泥缓凝剂。本发明为农业废弃物的高值化利用及其在建筑行业领域的应用提供了一条切实可行的技术路径。
