Title: Walter Laber - Innovator in Styrene Production
Introduction
Walter Laber, an accomplished inventor based in Deggendorf, Germany, has made significant contributions to the field of chemical engineering, particularly in the production of styrene. With a total of five patents to his name, Laber has focused on innovative processes that enhance efficiency and reduce energy consumption in industrial applications.
Latest Patents
Among his latest innovations, Laber has developed a process for producing styrene through the dehydrogenation of ethyl benzene. This process involves introducing a mixture of ethyl benzene and steam into a tubular reactor, where the tubes are heated using molten salts. Key parameters of this method include a tube diameter of 20 to 35 millimeters and a molten salt temperature ranging from 580°C to 660°C, ideally no more than 20°C above the catalyst reaction temperature. This innovative approach notably reduces steam consumption, ultimately saving energy and enhancing process efficiency.
Another significant patent relates to a catalytic process for converting ethylbenzene to styrene. This method operates at around 600°C with water vapor in a tubular reactor. The heat necessary for the dehydrogenation is supplied via a molten salt bath, maintaining the ethylbenzene-water-vapor mixture's entry temperature at 50°C to 100°C below that of the molten salt bath. This process operates isothermally and can be executed under atmospheric or subatmospheric pressure with a specific water vapor-ethylbenzene ratio.
Career Highlights
Walter Laber has established his career with notable contributions while working at prestigious companies. He has been associated with Deggendorfer Werft und Eisenbau GmbH and Metallgesellschaft Aktiengesellschaft, where he has played crucial roles in various projects related to chemical manufacturing and engineering.
