Title: Paul A Howley: Innovator in Hydroprocessing Technologies
Introduction
Paul A Howley is a notable inventor based in Woodbury, NJ (US), recognized for his contributions to the field of hydroprocessing technologies. He holds a total of 3 patents, showcasing his innovative approach to producing clean distillate fuels and enhancing catalytic processes.
Latest Patents
One of Howley's latest patents is focused on 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 using a commercial catalyst with a hydrogenation component. The heavier stream is treated in the presence of hydrogen at higher pressures, from 600 to 2000 psig, with a catalyst that has a Constraint Index of less than 2, in addition to a hydrogenation component, achieving 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.
Another significant patent by Howley involves the catalytic hydrodealkylation of aromatics. This process allows for the hydrodealkylation of alkylaromatic hydrocarbons to produce benzene or BTX over a catalyst comprising a specific metal and a synthetic zeolite. The zeolite is characterized by an X-ray diffraction pattern that includes interplanar d-spacings at various Angstroms.
