Title: Theis Ohlhaver: Innovator in Chemical Engineering

Introduction

Theis Ohlhaver is a notable inventor based in Frankfurt am Main, Germany. He has made significant contributions to the field of chemical engineering, particularly in the area of reforming processes. With a total of 3 patents to his name, Ohlhaver's work has had a considerable impact on the industry.

Latest Patents

One of Ohlhaver's latest patents is a method for starting up a pre-reforming stage in an integrated reforming plant. This method involves converting a hydrocarbonaceous feed stream, such as natural gas, into a reformation product that contains carbon oxides, hydrogen, and hydrocarbons. The catalyst in the pre-reforming stage is initially in an oxidized or passivated state. To activate it, the catalyst is charged with a methanol/steam mixture, which produces the necessary hydrogen through steam reformation of methanol in situ. The excess hydrogen generated is then utilized for the hydrogen supply of the desulfurization stage located upstream of the pre-reforming stage.

Another significant patent by Ohlhaver is a process for producing short-chain olefins with a prolonged cycle time. This process involves the conversion of oxygenates in a multi-stage fixed-bed reactor. The individual reaction zones are covered with beds of a granular, form-selective zeolite catalyst. The feed mixture containing oxygenates is added in a distributed manner across the reaction stages. This innovative approach increases the availability of the fixed-bed reactor for olefin production while maintaining or enhancing the yield of short-chain olefins.
