Title: The Innovative Contributions of Karl Z Steigleder

Introduction

Karl Z Steigleder is a prominent inventor based in Glen Ellyn, IL (US). He has made significant contributions to the field of chemical engineering, particularly in the development of processes for converting hydrocarbons into valuable products. With a total of 16 patents to his name, Steigleder's work has had a substantial impact on the industry.

Latest Patents

Among his latest patents is a process to convert aliphatics and alkylaromatics to light olefins with an acidic catalyst. This innovative process involves contacting a feed stream comprising C to C hydrocarbons, which contain at least 10 wt % paraffins and at least 15 wt % alkylaromatics, with an acidic catalyst. The result is a cracked product that includes light olefins and aromatics. The catalyst used in this process comprises about 30 to about 80 wt-% of a crystalline zeolite and a low-acidic binder, and it can be regenerated.

Another notable patent is a method for preparing a dehydrocyclodimerization catalyst. This invention addresses the reactivation of dehydrocyclodimerization catalysts that contain an aluminum phosphate binder, which can become deactivated when exposed to hydrogen at high temperatures. The process restores the catalyst's lost activity by treating it with a fluid comprising water and drying it. This method is particularly advantageous when combined with coke removal for reactivating catalysts that have been hydrogen deactivated.
