12月26日至12月30日，2024年《国家污染防治技术指导目录(鼓励类)》(公示稿)公示。
相较此前的2024年《国家污染防治技术指导目录(鼓励类)》(征求意见稿)，从19项变更为了16项。
对比如下：
被删除的水泥窑烟气催化复合脱硫技术——
在水泥生料中掺混加入V/Ti类催化剂、钙基吸收剂和矿化剂，将预热分解炉烟气中SO2催化氧化为SO3，并与生料反应生成CaSO4；同时在连接风管处喷入雾化后脱硫水剂吸收剩余SO3生成H2 SO4液滴，吸附在生料颗粒表面并快速生成CaSO4。脱硫产物经气固分离后随生料进入回转窑，CaSO4与SiO2、Al2 O3反应生成更稳定的硅铝酸钙后随熟料排出窑外，实现生产过程协同烟气脱硫。
当SO2浓度≤1000mg/m3时，出口烟气SO2浓度≤35mg/m3。
脱硫设施建设成本低，运行适应性好，无新增废水和废渣。
被删除的等离子体耦合喷淋洗涤恶臭治理技术——
利用高压放电产生的高浓度低温等离子体，降解废气中部分恶臭组分，残留臭氧和污染物通过喷淋洗涤去除。
以某除臭工程为例，治理前臭气浓度1738～2344(无量纲)，治理后臭气浓度132～174(无量纲)。
等离子体浓度高，除臭效果好，占地面积小。
被删除的微克级工业烟尘过滤材料和装备——
以线隙孔为主的聚四氟乙烯中空纤维膜作为滤材，制备过滤组件及配套装备，用于含铅等重金属烟气治理。
出口烟气颗粒物浓度2ug/m3～50ug/m3。
细颗粒物去除效率高；占地面积小。
