Title: Wolfdieter Klein: Innovator in Chemical Processing
Introduction
Wolfdieter Klein is a notable inventor based in Recklinghausen, Germany. He has made significant contributions to the field of chemical processing, particularly in the delignification of cellulosic materials and the hydrogenation of hydrocarbon substances. With a total of 3 patents to his name, Klein's work has had a considerable impact on industrial applications.
Latest Patents
Klein's latest patents include innovative methods for the delignification of cellulose-containing raw materials. His first patent describes a three-stage process that begins with pulping using a concentrated aqueous acetic acid solution at elevated temperatures and pressures. The resulting acetic acid-moist pulp undergoes further treatment with nitric acid and is subsequently washed or extracted. In the final stage, the pulp is treated with an ozone-containing gas, enhancing the delignification process.
Another significant patent involves a method for processing hydrocarbon substances, including coal and heavy crude oil. This method entails hydrogenating the hydrocarbon substance with a hydrogen-rich gas under high pressure and temperature. The process aims to produce a hydrogenation residue, which is then subjected to a secondary stripping operation to recover light hydrocarbon gases.
