Title: Innovations of Raymond N Cahen

Introduction

Raymond N Cahen is a notable inventor based in Etterbeek, Belgium. He has made significant contributions to the field of polymer chemistry, particularly in the hydrogenation processes of olefin polymers. With a total of 2 patents to his name, his work has implications for the production of high-quality white oils.

Latest Patents

Cahen's latest patents focus on a hydrogenation process for olefin polymers that are derived from olefin units containing four carbon atoms. The first patent discloses a method for producing white oils with a low iodine value, specifically below 0.26, under relatively mild reaction conditions. This process utilizes a catalyst comprising platinum on an alumina support with a total pore volume of at least 0.25 ml/g, where approximately 90 to 98% of the pores have a mean size of less than 100A. The second patent also addresses the hydrogenation of olefin polymers, employing a catalyst made of palladium on a bimodal alumina support. This support exhibits a total pore volume of at least 0.25 ml/g, with 35 to 50% of the pores being small (mean size below 300A) and 25 to 35% being large (mean size above 300A), which is at least 1.5 times the size of the small pores.
