The present invention provides apparatuses and processes for producing high octane fuel from synthesis gas. The process combines transalkylation and zeolite-forming/aromatization in conjunction with a single recycle loop configuration in order to effectively promote the fuel quality, particularly octane rating. The process involves adding a step for enriching octane of the fuel coming from the single recycle loop process. Preferably, the enrichment step takes place in an octane enrichment reactor containing two different catalysts, a zeolite-forming/aromatization catalyst followed by a transalkylation catalyst. The final fuel product preferably has an octane of about 92 to about 112.
