ABSTRACT:
An adsorbent is used to recover methanol in unreacted C.sub.4 's from the MTBE process. Methanol is desorbed from the mixture in a closed loop regeneration system utilizing a circulating vapor at an elevated temperature. Gas from the adsorber is cooled to condense methanol which may be recycled to the MTBE reaction. Unreacted C.sub.4 's substantially free from methanol may be used in HF or sulfuric acid alkylation.
