In contrast to conventional ethylene oxide (EO) production methods, this invention employs a new catalyst, a different oxidant, and much milder operating conditions. This inventive method eliminates carbon dioxide waste and converts ethylene to EO with greater than 99% selectivity. In addition to increased efficiency and a reduced carbon footprint, this invention offers safety advantages over conventional methods.
The current inventions utilizes a novel metal based catalyst in order to allow for the use of hydrogen peroxide as an oxidant allowing for a greener approach to olefin epoxidation. Further this method employs a catalyst that allows for less metal leaching, decreases hydrogen peroxide decomposition, and no carbon dioxide byproduct as demonstrated by gas chromatography.
This method utilizes a novel solid catalyst made specifically for olefin epoxidation. The catalyst utilizes a base in order to allow hydrogen peroxide to be utilized as an oxidant. Further the system allows for a constant flow of feedstock to flow through the catalyst with minimal leaching of the metal from the catalyst allowing for a longer life of the catalyst.
The current invention allows for the efficient catalysis of alkylene starting materials to make epoxidation products. The increase in efficiency allows for more of the starting material to be converted into the desired epoxide. This technology has applications in the natural gas industry, materials industry, and green catalyst industry to improve efficiency.
This invention has a novel catalyst composition that allows for alkylene feedstock to be passed over the catalyst to efficiently form a desired epoxide product for industrial use.
The catalyst allows for efficient production of an olefin to an epoxide while preventing the complete oxidation of the feedstock to carbon dioxide. Complete oxidation equates to a loss of suitable starting material, and in turn, revenue.
This catalyst is significantly greener than previous methods of olefin epoxidation. Hydrogen peroxide is efficiently used as the oxidant and metal leaching is decreased to provide a catalyst with a longer life.
The applications are numerous as the products formed are desirable in a number of industries.
