Latest Patents

Stacey holds a patent for a method titled "Removal of nitrogen compounds from FCC distillate." This invention focuses on the removal of nitrogen compounds from FCC feed or catalytically cracked distillates, including FCC cycle oils. The method utilizes formaldehyde to selectively couple organic heterocyclic nitrogen species, forming higher boiling coupling products that fall outside the boiling range of FCC distillate. This process enhances the operation of subsequent hydrodesulfurization steps, ensuring that the distillate fraction meets low sulfur standards. The formaldehyde is preferably used in the form of paraformaldehyde, and the reaction is conveniently conducted in the cycle oil pumparound circuit of the FCC main column.
