Title: David J Patmore: Innovator in Hydrocarbon Processing

Introduction

David J Patmore is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of hydrocarbon processing, holding a total of 4 patents. His work focuses on improving the efficiency and effectiveness of oil emulsions and heavy hydrocarbon oils.

Latest Patents

One of his latest patents involves upgrading oil emulsions with carbon monoxide or synthesis gas. This innovative process provides several procedures for the thermal rearrangement of a water emulsion or a mixture with water, utilizing feedstocks such as tar sand bitumen, heavy oil, refinery residue, and heavy waste oil streams. The essence of this procedure is to contact the water emulsion or mixture with a gas selected from synthesis gas and carbon monoxide, in the presence of a bifunctional catalyst. This catalyst facilitates the water gas shift reaction and promotes the hydrogenation and stabilization of cracking reaction products. The process is conducted under specific conditions of pressure and temperature, resulting in thermally rearranged liquid oil with lower viscosity and density than the original feedstock. Additionally, separate streams of gaseous carbon dioxide and hydrogen are recovered.

Another significant patent by Patmore describes a process for hydrocracking heavy hydrocarbon oils, achieving pitch conversions of over 90%, and preferably over 95%. In this process, a slurry of heavy hydrocarbon oil and carbonaceous additive particles, such as coal, is passed through a confined vertical hydrocracking zone under high temperatures and pressures. The top effluent, which is almost entirely gaseous, is removed from the hydrocracking zone, while a drag stream containing unreacted carbonaceous additives, metals, and unconverted pitch is also extracted. This innovative approach results in an effluent that is substantially free of pitch and metals.
