A process for making primary haloalkanes by catalytic distillation of internal haloalkanes which comprises a) introducing an internal haloalkane feed into a catalytic distillation column; b) isomerizing at least a portion of the internal haloalkane feed in the presence of an internal haloalkane isomerization catalyst at a temperature at or above the boiling point of the internal haloalkanes and below the temperature and pressure at which hydrogen halide is formed to form primary haloalkanes; and removing the primary haloalkanes from the catalytic distillation column.

Catalytic distillation process for primary haloalkanes

This invention provides for a process to convert branched or linear alkanes to branched or linear alpha olefins (AO) of the same carbon number. The process comprises the steps of: a) halogenating linear alkanes, branched alkanes, or a mixture of linear and branched alkane to produce a mixture containing primary mono-haloalkanes and hydrogen halide; b) separating the hydrogen halide from the mixture and optionally neutralizing it with a metal oxide to produce a partially halogenated metal oxide and/or metal halide which may be regenerated; c) separating the primary mono-haloalkanes from the mixture; d) reacting the separated primary mono-haloalkanes with a metal oxide to produce a mixture of products that contains alpha olefins, unconverted primary mono-haloalkanes, possibly other reaction products, and a partially halogenated metal oxide and/or metal halide which may be regenerated; e) regenerating the partially halogenated metal oxide and/or metal halide to halogen and/or acid and a metal oxide (such as Cl) for recycle by reaction with air or oxygen ; and f) removing the unreacted primary mono-haloalkane from the reaction mixture and then purifying the alpha olefin.

Process to convert linear alkanes into alpha olefins

This invention provides a process to convert alkanes to primary alcohols of the same carbon number. Carbon numbers of particular interest are Cto C. The process comprises the steps of: a) halogenating a linear or branched (or mixture of linear and branched) alkane to produce a mixture of primary mono-haloalkanes, internal mono-haloalkanes, unreacted alkanes, hydrogen halide, and possibly multi-haloalkanes in the presence of a catalyst and/or by heating the reaction mixture; b) separating the hydrogen halide from the mixture and optionally neutralizing it with a metal oxide to produce a partially halogenated metal oxide and/or metal halide which may be regenerated; c) separating the primary mono-haloalkanes from the mixture; d) reacting the separated primary mono-haloalkanes in a reactor with a metal oxide or combination of metal oxides and water to convert the aforesaid primary mono-haloalkane to a mixture of products that contains primary alcohols, unconverted primary mono-haloalkanes, and possibly other reaction products, and a partially halogenated metal oxide and/or metal halide which may be regenerated; e) regenerating the partially halogenated metal oxide and/or metal halide to halogen (such as Cl) and/or acid and a metal oxide for recycle by reaction with air or oxygen; and f) removing the unreacted primary mono-haloalkane from the reaction mixture and then purifying the primary alcohol.

Process to convert alkanes into primary alcohols

Ring opening cross metathesis of secondary non-cyclic hydrocarbons with cyclic unsaturated hydrocarbons having 8 carbon atoms or more to produce corresponding unsaturated product hydrocarbons having more than 8 carbon atoms.

Linear and branched olefin production from cyclic olefin feedstocks

Process for separating C2-C3 olefins from industrial gases

A process for separating and isolating saturated hydrocarbons from olefins, and in particular, a process for separating and isolating saturated hydrocarbons from olefins in a Fisher-Tropsch stream. The feedstock composition is contacted with linear polyaromatic compound under conditions effective to form linear polyaromatic compound-olefin adducts. Separation of the adducts from the stream also separates the adducted olefins from the stream. After dissociation of the adducted olefins, the process results in an olefin composition that is enriched in concentration of olefins over the concentration of olefins in the feedstock composition, and a saturated hydrocarbon stream that is enriched in saturated hydrocarbons over the concentration of saturated hydrocarbons in the feedstock.

Process for separating internal and alpha olefins from saturated compounds

A process for separating and isolating olefins from saturated hydrocarbons, preferably in a Fischer Tropsch stream, by adducting the olefins with a linear polyaromatic compound and separating the adducts from the remainder, which comprises saturated hydrocarbons.

Process for separating olefins from saturated hydrocarbons

Process for separating linear alpha olefins from a crude stream containing saturated hydrocarbons, internal olefins, branched olefins, and linear alpha olefins

There is provided a process for separating olefins from saturated hydrocarbons in a feedstock containing saturated hydrocarbons, internal olefins, and alpha olefins characterized by steps of selectively forming of olefin-linear polyaromatic compound adducts and steps of dissociation of these adducts.

Process for separating saturated compounds from olefins

This invention relates to a process for separating functionalized alpha olefins from functionalized internal olefins. The process achieves by a step of contacting a feedstock containing functionalized alpha olefins and functionalized internal olefins with a linear polyaromatic compound to form a linear polyaromatic compound-functionalized alpha olefin adduct and a step of dissociating the linear polyaromatic compound-functionalized alpha olefin adduct to form linear polyaromatic compounds and a functionalized alpha olefin composition.
