With a total of five patents to his name, Shoffner has demonstrated a commitment to advancing technology and improving industrial processes.
Latest Patents
One of Shoffner's latest patents focuses on the isomerization of cresols. This process involves the isomerization reaction of a cresol in the presence of a crystalline aluminosilicate zeolite catalyst and added hydrogen. The inclusion of hydrogen enhances the stability and longevity of the catalyst while ensuring a more stable selectivity to the desired isomers. The reaction occurs at temperatures ranging from approximately 250 to 450 degrees Celsius and pressures between 2 to 75 atmospheres, with hydrogen present in a mole ratio of about 1:1 to 10:1 moles of hydrogen per mole of cresol.
Another significant patent addresses the regeneration of electrical conductivity in metallic surfaces. This process allows for the in situ treatment of metallic surfaces using a regenerating agent, specifically a hydrogen halide such as hydrogen chloride. The hydrogen halide can be applied in liquid, gaseous, or vaporous form. Additionally, an ammonium salt like ammonium chloride may be utilized to enhance the regenerative effects of the hydrogen halide. For instance, treating steel surfaces with hydrogen chloride and ammonium chloride promotes the formation of ferric oxide, which exhibits greater electrical conductivity than ferrous oxide.
