Abstract
In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, the disclosure relates to a method for producing C4 olefins from acetylene using supported metal-based catalysts and metal-based promoters. The method is inexpensive, efficient, and environmentally sound. Additionally, the method is selective for C4 olefins and other value-added products based on changes to reaction parameters including temperature, feed gas composition, and promoter identity. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
Claims22
A method for producing C4 olefins from acetylene, the method comprising:
- a. placing a catalyst in a reactor;
- b. providing a flow of feed gas through the reactor;
- c. reacting the feed gas at a first temperature for a first period of time to produce a product mixture;
- and
- d. collecting the product mixture;
- wherein the catalyst comprises a first metal;
- wherein the first metal is selected from Cu, Fe, Co, Ni, Pd, Pt, Rh, and combinations thereof;
- and
- wherein the first metal is present in an amount from about 5 wt % to about 15 wt %:
- wherein the catalyst comprises a promoter;
- wherein the promoter comprises a second metal;
- wherein the second metal is selected from Ru, Ga, Ag, and combinations thereof;
- and
- wherein the second metal is present in an amount from about 0.05 wt % to about 10 wt %;
- wherein the catalyst further comprises a catalyst support;
- wherein the catalyst support is selected from a material comprising SiO2, Al2O3, ZrO2, TiO2, CeO2, a zeolite, ammonium zeolite mordenite, and combinations thereof;
- wherein the feed gas comprises acetylene;
- and
- wherein the product mixture comprises at least one C4 olefin.
