Abstract

A Fischer-Tropsch-based process and system for converting light hydrocarbons into heavier hydrocarbons uses a plurality of different synthesis gas generators. The process includes preparing a first synthesis gas having a H2:CO ratio greater than 2:1; removing a portion of the hydrogen from the first synthesis gas; preparing a second synthesis gas with a CO2 recycle wherein the second synthesis gas has a H2:CO ratio less than 2:1; adding the removed hydrogen to the second synthesis gas to increase the H2:CO ratio of the second synthesis gas; and using a Fischer-Tropsch reaction to convert the first synthesis gas and the second synthesis gas to heavier hydrocarbons.
