A process for the manufacture of ether from a feedstock containing isoolefins and linear olefins. The process is one which has a high conversion of isoolefins thereby permitting the separation of linear olefins without the associated difficulty in separating isomers.

Process for manufacturing ether and high purity butene-1

This invention provides an improved etherification process that reduces the amount of acidic-ion-exchange-resin catalyst that is deactivated by nitriles. This process uses a water phase to remove nitriles from a hydrocarbon phase followed by an alcohol phase to remove the nitriles from the water phase. An hydrogenation catalyst is used to convert the nitriles to amines so that they can be more easily removed from the alcohol phase.

Etherification process

This invention provides a process to remove nitriles. This invention also provides an improved etherification process that reduces the amount of acidic-ion-exchange-resin catalyst that is deactivated by nitriles. These processes use a water phase to remove nitriles from a hydrocarbon phase followed by a steam, or fuel gas, phase to remove the nitriles from the water phase.

In a process for manufacture of a chemical product, a reactive hydrocarbon feedstream, which varies in composition of the reactive component, is combined with a compatible but unreactive hydrocarbon feedstream to form a blended hydrocarbon stream which is then combined with a reactive alcohol stream of stable concentration of its reactive component, to form a complete feedstream to the reactor. A desired ratio of relative reactant concentrations in the complete feedstream to the reactor is maintained by a control system which maintains a stable concentration in the blended hydrocarbon stream by manipulating flow rate of the unreactive hydrocarbon feedstream responsive to a concentration measurement in the blended hydrocarbon stream. Flow ratio control is then applied to maintain a desired ratio of reactants in the complete feedstream for the reactor by calculating a flow ratio of the blended hydrocarbon stream to the reactive alcohol feedstream. The calculated flow ratio is the process variable input to a manually set ratio controller which manipulates the flow rate of the reactive alcohol feedstream responsive to the flow ratio.

A novel integrated olefin processing scheme is provided where olefins and paraffins are processed to produce high octane gasoline blending components. The integrated process involves the dehydrogenation of paraffin compounds to olefin compounds and the processing of olefins by hydroisomerization to produce hydroisomerate streams which are subsequently etherified. Those olefin compounds which are not etherified pass to an alkylation process where they are alkylated with branched chain paraffin compounds to produce an alkylate product.

Integrated olefin processing

In the liquid phase catalytic oxidation of organically polluted water containing negligible amounts of alkali metal by contacting the polluted water with an oxygen-containing gas and a catalyst effective to promote such liquid phase oxidation, the method of increasing the catalyst life comprising increasing the alkali metal concentration in the organically polluted water prior to the catalytic oxidation.
