    摘要: A combination process wherein a hydroisomerization system provides a hydrocarbon feed for an etherification system wherein unreacted alcohol is separated from the etherification effluent and passed to the fractionation column used in the hydroisomerization system so that water entrained in the unreacted alcohol can be separated from said alcohol within said fractionation column.

    摘要: A process for producing ethyl tertiary butyl ether and for the substantially complete recovery by fractional distillation of the unreacted ethanol contained in an etherification reaction zone product stream as a product along with the ethyl tertiary butyl ether reaction product. This process utilizes methanol as a fractionator feed additive to enhance the recovery of ethanol as a bottoms product.
