Title: Bernd Greving: Innovator in Isobutene Production

Introduction

Bernd Greving is a notable inventor based in Marl, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of high purity isobutene. His innovative approach has led to the development of a patented process that enhances the efficiency of isobutene production.

Latest Patents

Greving holds a patent for a process that produces high purity isobutene by dehydrating tertiary-butanol in an aqueous solution. This process involves a homogeneous and liquid phase dehydration at a fixed catalytic bed consisting of a strongly acidic ion exchange resin. The reaction occurs at temperatures ranging from 80 to 150 degrees Celsius and pressures between 5 to 25 bars. The resulting homogeneous liquid reaction mixture is then fractionated in a separate distillation sector, allowing for the effective separation of isobutene from water and unreacted tertiary butanol.

Career Highlights

Greving has been associated with Chemische Werke Huls Aktiengesellschaft, where he has applied his expertise in chemical processes. His work has not only contributed to advancements in isobutene production but has also positioned him as a key figure in the chemical industry.
