Abstract

The comment and response concerning the report of oxidation of methane to methanol by water (Reports, 5 May 2017, p. 523) do not fully capture the implications of thermodynamic limitations. A nonisothermal process in which each cycle requires a large temperature swing and permits only substoichiometric methane conversion surely could not be carried out on any practical scale.

摘要

关于甲烷氧化为甲醇的水报告的评论和回复（报道，2017 年 5 月 5 日，第 523 页）并没有完全捕捉到热力学限制的影响。如果一个非等温过程每个循环都需要大幅度的温度波动，并且只能进行亚化学计量的甲烷转化，那么这个过程肯定不能在任何实际规模上进行。
