Abstract
The present invention relates to a method and gasification system for recycling methane-rich gas from syngas stream emanating from fluidized bed reactor and then returning the methane to the fluidized bed reactor. The method comprises recovering methane-rich gas from the synthesis gas and delivering at least a portion of the recovered methane-rich gas to the fluidized bed reactor. Methods to recover methane-rich gas from syngas at different steps in the gasification system are also provided herein.
