Title: Innovations of Denis H Thornhill in Heavy Metal Recovery

Introduction

Denis H Thornhill is an accomplished inventor based in Caracas, Venezuela. He is known for his innovative work in the field of heavy metal recovery from carbonaceous materials. His contributions have significant implications for environmental sustainability and resource recovery.

Latest Patents

Thornhill holds a patent for a process and apparatus designed to recover heavy metals, particularly vanadium pentoxide, from petroleum coke. The patented method involves combusting petroleum coke under controlled temperature conditions ranging from 680°C to 1400°C. The resulting ash is then processed to extract valuable metallic compounds. This innovative approach can be executed in a fluidized bed furnace, although higher recovery rates are achieved using a tubular furnace chamber inclined at 10 degrees to horizontal. The process utilizes dried petroleum coke, ground to a fine powder, which is entrained into a primary air flow and combined with secondary air to maintain an oxidizing atmosphere. The molten slag produced is deposited on the chamber wall and subsequently drained to fall onto a rotating steel drum immersed in a water trough, where it is collected and removed.
