Title: Ulrich Graeser: Innovator in Coal Hydrogenation
Introduction
Ulrich Graeser is a notable inventor based in Haltern, Germany. He has made significant contributions to the field of coal hydrogenation, holding a total of 4 patents. His innovative processes aim to enhance the efficiency and effectiveness of converting coal into valuable energy resources.
Latest Patents
Graeser's latest patents include a groundbreaking process for the hydrogenation of coal. This process involves slurrying pulverized coal with oil, hydrogenating the mixture at elevated temperatures and pressures, and separating the liquid and solid reaction products from the gaseous reaction products. The slurry oil used contains non-process derived hydrocarbon mixtures with a boiling range above about 200°C, comprising 30-100% by weight, with the remainder being process-derived oils. Another significant patent focuses on the production of reformer feed and heating oil or diesel from coal. This process introduces a pulverized coal-oil slurry along with hydrogenation gas into a liquid-phase hydrogenation stage, allowing for the removal of solids and the cooling of the resulting volatile coal-oil fraction. Notably, this invention reduces the operating pressures required during gas-phase hydrogenation to approximately 50-200 bars, significantly lowering hydrogen consumption compared to conventional methods.
