自Keller和Bhasin进行先行工作以来,CH_4氧化偶合为C_2H_6和C_2H_4(C_2化合物)引起人们广泛注意。我们曾报道Sm_2O_3是该反应的一种具有活性和选择性的催化剂。但是,对此催化剂试验所用的低氧压(0.4KPa)、高P_(CH_4):P_(O_2)之比(45)和低反
Since the pioneering work of Keller and Bhasin, the oxidative coupling of CH_4 to C_2H_6 and C_2H_4 (C_2 compounds) has attracted much attention. We have reported that Sm 2 O 3 is an active and selective catalyst for this reaction. However, the low oxygen pressure (0.4KPa), the high P_ (CH_4): P_ (O_2) ratio (45) and the low reverse
