摘　　要：木质素磺酸钙(CLS)催化转变制取化学品是实现CLS资源化和高值化利用的重要途径。利用水热合成法制备MgO、NiO、Fe_(2)O_(3)、MgFeO_(x)、NiFeO_(x)和NiMgFeO_(x),并对其进行晶相和结构分析,在水热反应体系中评价了其对CLS的催化解聚性能。结果表明,NiMgFeO_(x)比表面积最大,为81.72m^(2)/g;在NiMgFeO_(x)催化解聚CLS过程中,存在金属活性中心和固体碱中心的协同催化作用,液相产物总收率为75.82%,其中酚类化合物收率可达59.59%,主要为苯酚类、愈创木酚类和紫丁香酚类化合物。Catalytic conversion of calcium lignosulfonate(CLS)to produce chemicals is an important way to realize high-value utilization of CLS.MgO,Ni O,Fe_(2)O_(3),MgFeO_(x),Ni FeO_(x)and Ni MgFeO_(x)are synthesized via hydrothermal synthesis method,their crystal phase and structure are analyzed,and their catalytic performance for depolymerization of CLS is evaluated in a hydrothermal reaction system.Results show that Ni MgFeO_(x)shows the maximum specific surface area,reaching 81.72 m^(2)·g^(-1).During the catalytic depolymerization of CLS over Ni MgFeO_(x),there exists a synergistic catalytic effect between metal active centers and solid base centers,and total yield of liquid phase products reaches75.82%,of which the yield of phenolic compounds reaches 59.59%,mainly including phenols,guaiacols and eugenol compounds.
