Latest Patents

One of Zinkie's latest patents is titled "Removal of sulfur compounds from hydrocarbon feedstreams using cobalt containing adsorbents in the substantial absence of hydrogen." This innovative process addresses the challenge of removing sulfur compounds from hydrocarbon feedstreams, especially those boiling in the naphtha range. The method involves contacting the feedstream with an adsorbent that contains cobalt and one or more Group VI metals, such as molybdenum and tungsten, on a refractory support. Additionally, this invention includes a process where a naphtha feedstream undergoes selective hydrodesulfurization to eliminate sulfur without significantly saturating olefins. The resulting product stream, which contains mercaptans, is treated using the cobalt-containing adsorbents developed by Zinkie.

Another significant patent is the "Method for upgrading waxy feeds using a catalyst comprising mixed." This discovery reveals that waxy feeds can be effectively upgraded by utilizing a catalyst created from a combination of powdered dewaxing catalyst and powdered isomerization catalyst. The mixture of these powdered catalysts is formed into discrete particles, enhancing the upgrading process.
