Process for reducing methane production and increasing liquid yields in Fischer-Tropsch reactions

摘要

A process for reducing methane formation and increasing liquid yields in Fischer-Tropsch processes for synthesizing hydrocarbons from CO and H₂ comprising adding water and/or an olefin to the top of the reactor bed or to the reactor feed at a point below 10% of the distance from the top to the bottom of the reactor bed and above a point 10% above the bottom of the reactor bed to the top of the reactor bed in an amount sufficient to reduce said methane formation, wherein the molar ratio of water (when employed) to CO is from about 0.1 to about 5.
