中化新网讯日前，水富云天化年产26吨甲醇装置第二变换炉采用青岛联信开发的新型QDB-07耐硫变换催化剂后，出口硫醇硫醚含量从28mg/m³降低到11mg/m³，解决了高CO含量和高硫原料气变换工段硫醇硫醚生成的问题。

　　水富云天化年产26吨甲醇装置，采用壳牌粉煤气化制气，低水气比耐硫变换工艺，粗煤气CO含量高、硫化物含量高，水气比为0.2~0.3。在装置的运行过程中，在变换炉出口检测到一定量的有机硫化合物(硫醇硫醚类)，对甲醇合成工序的正常运行产生较大影响。

　　针对变换炉出口有机硫含量升高的问题，青岛联信在原QDB-04催化剂的基础上，研制出一种适合高硫工况的新型QDB-07耐硫变换催化剂，能更有效地抑制有机硫生成。2021年4月，水富云天公司对第二变换炉进行整炉更换，与更换前相比，更换后第二变换炉出口硫醇硫醚含量从28mg/m³降低到11mg/m³，使硫醇硫醚转化率达到61%，较好地解决了高CO含量和高硫原料气变换工段硫醇硫醚生成的问题。

　　我国高硫煤产量约占总储煤量的1/3，高硫煤的开发利用一直是业界研究的重要课题。QDB-07催化剂的开发成功，解决了高硫煤在节能型变换工艺中应用的关键技术难题，保障了节能型新工艺的实施，拓宽了原料煤的选择范围并降低原料煤采购成本，为高硫煤的推广应用起到了良好的示范效应。
