Latest Patents

Holtmann's latest patents include a method for producing propylene from methanol. This innovative process involves reacting methanol vapor on a first catalyst to obtain a vapor mixture containing dimethyl ether (DME). The DME is then reacted on a form-selective zeolite catalyst in at least two series-connected shaft reactors to produce a product mixture containing propylene. Another significant patent is the process of generating C₃ and C₄ olefins from a feed mixture. In this process, a feed mixture containing C₄ olefins to C₇ olefins is evaporated and mixed with steam. The steam-containing feed mixture is introduced into a reactor containing a bed of granular, form-selective zeolite catalyst, resulting in a product mixture with a high content of propylene and butene isomers.
