Oxidative coupling process for converting methane and/or natural gas to more transportable products

Robert H. Walker, +5 more
TLDR
In this paper, a method for converting methane to higher molecular weight hydrocarbons was proposed, where hot oxidative coupling reactor effluent is briefly contacted with a C2 to C20 alkane quench material to remove part of the heat contained in the raw reaction effluent, and further quenched by thermal quenching means to achieve a temperature which discourages retrograde reactions.
