Abstract

Official abstract text for this publication.

Systems for preparing butenes are provided. The systems can include a reactor inlet coupled to both a reactor and at least one reactant reservoir; at least one of the reactant reservoirs containing one or both of an aldehyde and/or ethanol; a catalyst within the reactor, the catalyst comprising a metal component and an acidic support material; and a reactor outlet operationally configured to convey a butene-rich reaction product to a product reservoir. Methods for preparing butenes are also provided. The methods can include exposing one or both of ethanol and/or an aldehyde to a catalyst comprising a metal component and an acidic support to form a butene-rich product that comprises one or both of 1-butene and/or 2-butene.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for preparing butenes, the method comprising exposing an aldehyde to a catalyst comprising Zn and/or Ga in addition to Cu, ZrO 2 , and SiO 2 to form a butene-rich product that comprises 1-butene and/or 2-butene. 2. The method of claim 1 wherein the aldehyde is mixed with an ethanol and exposed to the catalyst to form the butene-rich product. 3. The method of claim 1 wherein the catalyst further comprises Al, zeolite, Zn, alumina, or a combination thereof. 4. The method of claim 3 wherein the catalyst comprises 0.5-20 (wt/wt %) Cu. 5. The method of claim 3 wherein the catalyst comprises 1-8 (wt/wt %) ZrO 2 . 6. The method of claim 1 wherein the aldehyde comprises acetaldehyde, butraldehyde, crotonaldehyde, or a combination thereof.
