  • Patent number: 10584085
    Abstract: The present invention relates to a process for etherification of mixed olefinic light naphtha boiling in the range of C5-90° C. cut with simultaneous minimization of unreacted methanol concentration in the product. The etherification of mixed olefinic light naphtha produces the high octane blending component which can be blended directly in the gasoline pool without any recovery of the feed oxygenates like methanol, ethanol etc. which conventionally uses energy intensive separation processes.
