Abstract

A mixture of 13C-labeled methane (500 equiv; 64 kPa) and ethane (10equiv; 1.25 kPa) was heated at 1658C over 1 (53 mg, 5wt% in Ta (see Method of preparation in Experimental Section)) in a glass reactor (0.28 L), and the distribution of the 13Cisotopomers of ethane (unlabeled, mono-, and dilabeled) was monitored over time by GC/MS. Incorporation of 13C labels in ethane occurred over 200 h; hydrogenolysis of ethane into methane was also ...
