Title: Hubert Puestel: Innovator in Hydrocarbon Oil Preparation
Introduction
Hubert Puestel is a notable inventor based in Dannstadt-Schauernheim, Germany. He has made significant contributions to the field of hydrocarbon oil preparation from coal. With a total of 2 patents to his name, his work focuses on innovative processes that enhance the efficiency of hydrocarbon production.
Latest Patents
Puestel's latest patents include a method for the continuous preparation of hydrocarbon oils from coal by hydrogenation. This process involves cracking hydrogenation under pressure in two stages. In the first stage, milled coal is combined with finely divided catalysts and an oil mixture. The slurry is then hydrogenated by heating to temperatures between 380°C and 440°C under hydrogen pressures ranging from 200 to 700 bar. The gaseous and liquid reaction products are separated from the solid products and undergo further hydrogenation in the gas phase, utilizing a fixed hydrogenation catalyst. Additionally, he has developed a multi-stage reactor designed for hydrogenating coal slurry in a pressure vessel capable of withstanding pressures of up to 700 bar. This reactor features inlets for gas and coal slurry, an outlet for sludge, gases, and vapors, and dividing trays that separate individual reaction stages.
