  • Recovery of methanol in an MTBE process
    Patent number: 4748281
    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.

  • Process for production of gasoline blending stock
    Patent number: 4731489
    Abstract: A process for producing a gasoline blending stock of methyl tertiary butyl ether and tertiary butyl alcohol wherein a first catalytic etherification of isobutene and methanol produces methyl tertiary butyl ether and unreacted methanol. The etherification product including isobutene and remaining methanol is reacted with water and fresh isobutene in a second catalytic reaction where both etherification and hydration occur. This essentially exhausts the methanol while the hydration reaction to tertiary butyl alcohol prevents undesired side reactions.
