A process for the etherification and separation of C. sub. 3 -C. sub. 5 hydrocarbons is improved by the advantageous integration of an oxygenate recovery unit having a 3-bed arrangement into the etherification separation section. A feedstream including C. sub. 3 hydrocarbons and isobutene are reacted with methanol in an etherification to produce an etherification effluent that is separated in a first separator into a bottoms stream of MTBE product and an overhead stream of unreacted isobutane, methanol, other oxygenate compounds and C. sub. 3 -hydrocarbons. After recovery of methanol, in an adsorptive separation process, the methanol deficient overhead stream enters a second separation zone in the form of depropanizer for the separation of isobutane and higher boiling hydrocarbons from the C. sub. 3 hydrocarbons. Any oxygenate compounds that are carried from the bottom of the column with the C. sub.

A process for the regeneration of oxygenate containing adsorbents uses regenerant streams such as LPG and isomerate products for the desorption of oxygenate compounds. The process discloses arrangements for the integration of regenerant treatment into the adsorption scheme and for the enhancement of the isomerate product. The integrated flowscheme can be used to remove sulfur and water from contaminated regenerants or to deliver the oxygenates into the gasoline pool.

The invention provides processes for the production of hydrocarbons from a biorenewable feedstock blended with a mineral feedstock comprises hydrotreating to remove heteroatoms and saturate olefins. The carbon monoxide is not fed to the downstream hydroisomerization reactor but supplanted with a hydrogen gas with a low concentration of carbon monoxide so as not to poison the hydroisomerization catalyst to improve the cold flow properties for a diesel fuel.
