Latest Patents
Rollmann holds a patent for the "Production of clean distillate fuels from heavy cycle oils." This invention discloses an enhanced process for the hydroprocessing of a feed, which comprises a highly aromatic refinery distillate stream boiling in the range between 300°F and 900°F. The feed is separated into light and heavy streams, with the light stream containing from 0.1 to 5 wt. % dibenzothiophene, substituted dibenzothiophenes, and heavier polycyclic thiophenes. The lighter stream is hydrotreated at pressures from 300°F to 1000°F with a commercial catalyst having a hydrogenation component. The heavier stream is treated in the presence of hydrogen at higher pressure, from 600 to 2000 psig, with a catalyst comprising active material having a Constraint Index of less than 2, in addition to a hydrogenation component, in order to achieve over 35% conversion of material boiling above 630°F. The active material of the catalyst is a highly siliceous zeolite or an acidic amorphous silica-alumina material. He has 1 patent to his name.
