A method and an apparatus for preparing an alpha-olefin. The method includes supplying a feed stream including a gaseous ethylene monomer to a monomer dissolution device to dissolve the feed stream in a solvent and form a liquid ethylene monomer, and supplying a feed stream including the liquid ethylene monomer as a discharge stream to a reactor, thereby removing heat of dissolution of the gaseous ethylene monomer outside of the reactor, and decreasing an amount of a refrigerant used in an alpha-olefin production process to improve economic feasibility.

Disclosed is a process for the regeneration of an adsorber. For the regeneration a liquid stream (S2) is applied which is obtained by hydrogenation of a stream (S1) comprising at least one alkane and least one olefin. The stream (S2) comprises one alkane and a reduced amount of at least one olefin compared to the amount in the stream (S1). Then the stream (S2) is converted from the liquid into the gaseous phase and the adsorber is regenerated by contact with the gaseous stream (S2).

A system and method for efficiently and sustainably producing propylene and acrylonitrile is disclosed which utilizes biodegradable materials, combustible materials that produce carbon dioxide and/or carbon monoxide. According to one embodiment of the invention, a source of carbon dioxide and/or carbon monoxide is utilized and the carbon dioxide and/or carbon monoxide is electrochemically reduced to ethylene. Dimerization is applied to separate the ethylene to produce 1-butene; which is isomerized to produce 2-butene. The 2-butene is metathesized to produce propylene. The propylene may then be subject to ammoxidation as desired in order to produce acrylonitrile.

This application relates to the production of functionalized lower hydrocarbons and more particularly to the process of converting ethanol to functionalized lower hydrocarbons. In particular embodiments, the ethanol to functionalized lower hydrocarbon conversion is catalyzed by a Zn.sub.xZr.sub.yA.sub.vQ.sub.sMn.sub.wO.sub.z mixed oxide catalyst or a bifunctional heterogeneous catalyst. In particular embodiments, the ethanol to be converted is present at molar concentrations in the reactor feed equal to or exceeding 14%.
