Title: **Leonard Nyadong: Innovator in Petroleum Refining**

Introduction

Leonard Nyadong, an accomplished inventor based in Owasso, Oklahoma, has made significant strides in the field of petroleum refining. With two registered patents to his name, his work focuses on enhancing the efficiency and safety of refining processes, particularly in relation to the challenges posed by nickel and vanadyl porphyrins.

Latest Patents

Nyadong's most recent patents are groundbreaking. The first patent is titled "Decreasing the adverse effects of nickel and vanadyl porphyrins in petroleum refining." This innovative process aims to reduce contamination in commercial refining processes by enabling the rapid screening of porphyrins directly from asphaltenes isolated from crude oil through positive-ion electrospray ionization mass spectrometry (ESI MS). By utilizing sodium formate as an ESI spray modifier, the process identifies vanadyl porphyrins predominantly as sodiated species, while nickel porphyrins appear as both sodiated species and molecular ions. Furthermore, crude oil feedstocks that exceed a certain concentration of these porphyrins are either rejected or diluted before entering the refinery.

His second patent, titled "Upgrading jet fuel using spent FCC equilibrium catalyst," addresses the practical challenges of jet fuel decontamination. This patent highlights the dual utility of spent zeolite equilibrium catalyst from fluidized catalytic crackers, serving as an effective adsorbent for contaminated jet fuel. This innovative solution not only reduces disposal costs associated with hazardous waste but also minimizes the expenses incurred in procuring new sorbents. Given that zeolite comprises mainly silica, its chemical similarity to conventional sorbents enables the spent catalyst to be regenerated and reused, thereby supporting more sustainable refining practices.
