The present invention discloses an integrated process and an apparatus for production of various alcohols and Oligomerization of Olefinic feed stocks comprising butylenes and mixture thereof. In this process the combined light olefinic hydrocarbon feedstock is divided into two streams and contacted in two different reaction zones, viz. hydration and oligomerization. The mixture of alcohols and oligomer product from hydration reaction is separated and the bottom stream from separator is routed to oligomerization reaction zone in a controlled quantity as selectivity enhancer. Both the reaction zones are operated at different conditions. The product from oligomerization zone is further separated in to lighter and heavier components. Each reaction zone may comprise series of reactors filled with acidic catalysts comprising ion exchange resins.

A process can be used for oligomerization of isobutene by conversion of an isobutene-containing hydrocarbon stream over an acid catalyst in at least one reaction stage, where a particular ratio of recycle to feed is employed.

A process for simultaneously hydrating and oligomerizing a hydrocarbon feed comprising mixed olefins incudes the steps of: (a) introducing the hydrocarbon feed in the presence of water into a fixed bed; (b) contacting the hydrocarbon feed with a catalyst within said fixed bed reactor, where the catalyst is of the type that hydrates the mixed olefins to form mixed alcohols and oligomerizes at least a portion of the mixed olefins into oligomers to produce a first product stream that includes an organic phase and an aqueous phase; (c) introducing the first product stream into a first separator which separates the organic phase from the aqueous phase; (d) introducing the separated organic phase into a second separator which separates unreacted olefins from mixed alcohols and one or more oligomers which comprise a final product stream; and (e) introducing the separated aqueous phase into a third separator which separates an alcohol-water azeotrope component from water.

Acyclic monterpene alcohols, like linalool, to be converted through a series of highly efficient catalytic reactions a biogasoline blending component, and a drop-in biodiesel fuel.

The present disclosure relates to a process and a production unit that are used to catalytically manufacture olefin trimers from olefin monomers, and wherein olefin dimers are recycled after dimerization reaction, and reacted with olefin monomers in an addition reaction.

Methods and systems for producing high purity methanol and isobutene from crude MTBE feed using multiple divided wall columns are provided. The methods can include purifying the MTBE, dissociating the MTBE to produce isobutene and methanol, purifying the isobutene and recovering/purifying methanol.
