新型Ni－La催化剂催化甲醇气相羰基化反应

 制备和测试一种全新的甲醇气相羰基化催化剂。催化剂的活性金属为Ni, La为第二组分，本身无催化羰基化活性，采用一种我们自行开发的新型碳分子筛为载体。在制备过程中，采用了一种全新的负载路线，即：以Ni-La双核配合物为金属微晶的前体，使得Ni-La按确定的原子比混合，由此得到全新Ni-La羰基化催化剂。La有很强的助催化作用，与未添加La的Ni催化剂相比，Ni-La催化剂表现出更高的催化活性和选择性。

Lanthanum-Promoted Nickel Catalyst for Vapor-Phase Methanol Carbonylation

Methanol carbonylation is the main process for producing acetic acid. The current technology is based on precious rhodium and iridium catalysts dissolved in liquid phase1,2]. A heterogeneous catalyst based on a cheaper metal will have much theoretical and economic significance in improving the methanol carbonylation process, by solving many problems in homogeneous process. To achieve this purpose, a lanthanum-promoted nickel catalyst supported on polymer-derived carbon beads3] with high activity and selectivity was developed by a new strategy.
