金融界2024年12月7日消息，国家知识产权局信息显示，宁夏华辉环保科技股份有限公司申请一项名为“低灰柱状煤质活性炭的制备方法”的专利，公开号 CN 119079988 A，申请日期为2024年9月。
专利摘要显示，本发明公开了一种低灰柱状煤质活性炭的制备方法，将太西煤和微粉超纯碳初步混合得到混合粉料A；将木质素溶解于适量二甲基乙酰胺中，再加入煤焦油混匀得到混合液B；将乙二酸与三乙胺加入适量二甲基乙酰胺中混合均匀得到混合液C，将混合粉料A加入捏合机混合均匀，然后向其中加入混合液B混匀，再向其中加入混合液C搅拌、混捏得到煤泥；将煤泥在成型设备上挤压成煤条，平铺自然晾干，再经过炭化活化制备得到活性炭。本发明通过对太西煤粉进行原料掺配和改性，优化活性炭孔隙结构，便于活性炭与活化剂接触活化，降低烧失率以及资源消耗和能耗，解决活性炭行业使用优质煤生产柱状活性炭所伴随的活化难度大、产量低以及能耗大等问题。
