Latest Patents

One of his latest patents is a process and apparatus for producing olefin. This invention provides a method for producing olefin with three or more carbon atoms from ethane in a simpler and more stable manner. The process involves obtaining a cold fraction by cooling an ethane-cracked gas, which is produced by thermal cracking of ethane in the presence of steam, to 600°C or less. This cold fraction is then brought into contact with a catalyst containing a medium pore diameter zeolite to yield olefins.

Another notable patent by Sekiguchi is focused on producing propylene and aromatic hydrocarbons. This improved process allows for a varied yield structure of components through a simple method. It utilizes a medium pore diameter zeolite-containing catalyst to produce propylene and aromatic hydrocarbons from a hydrocarbon feedstock containing olefins. The process includes a propylene production step where a specific zeolite catalyst is used to remove a hydrocarbon component from the reaction mixture, allowing for part of the hydrocarbon component to be recycled as necessary.
