Title: Innovations by Hans-Juergen Schoennagel

Introduction

Hans-Juergen Schoennagel is a notable inventor based in Lawrenceville, NJ (US). He holds a total of 4 patents that reflect his contributions to the field of chemical engineering and energy conversion. His work primarily focuses on processes that enhance the efficiency of coal conversion and hydrocarbon reforming.

Latest Patents

One of his latest patents involves a process for the catalytic devolatilization of coal. This innovative method utilizes a mixture of preheated coal particles and hot catalyst solids, which are contacted with gaseous materials such as steam or hydrogen-containing gas. The process is designed to create a high-temperature suspension in a riser reactor, promoting high yields of devolatilized liquid hydrocarbon products. Additionally, the quality of the devolatilized material is enhanced by the hot catalytic solids, which either convert devolatilized tars and phenols into more desirable products or prevent their formation altogether. The char produced through this technique is particularly suitable for subsequent gasification and other applications.

Another significant patent by Schoennagel pertains to the reforming of sulfur-containing charge stock. This process involves reforming a hydrocarbon charge under specific conditions while introducing sulfur to counteract excessive hydrocracking. The catalyst used in this process consists of a minor proportion of platinum on one support and a minor proportion of iridium on a separate support, showcasing his innovative approach to improving hydrocarbon processing.
