Title: Innovations of Norman J Rouleau
Introduction
Norman J Rouleau is a notable inventor based in Yardley, PA (US). He has made significant contributions to the field of hydrocarbon conversion, holding a total of 2 patents. His work focuses on processes that enhance the efficiency of converting heavy aromatic hydrocarbons into lighter products.
Latest Patents
One of his latest patents is titled "Process for converting C.sub.9 + aromatic hydrocarbons to lighter." This process involves reacting C.sub.9+ aromatic hydrocarbons and toluene or benzene under specific transalkylation reaction conditions. The reaction utilizes a first catalyst composition that includes a zeolite with a constraint index ranging from 0.5 to 3, along with a hydrogenation component. A second catalyst composition is also employed, which includes an intermediate pore size zeolite with a constraint index ranging from 3 to 12 and a silica to alumina ratio of at least about 5. The end result is a transalkylation reaction product containing benzene or toluene and xylene, which can be distilled to obtain the desired products.
Another significant patent is related to "Hydrocarbon conversion." This process upgrades a petroleum naphtha fraction by subjecting it to reforming. The reformate is then cascaded to a benzene and toluene synthesis zone, utilizing a catalyst that comprises a molecular sieve of low acid activity, preferably steamed ZSM-5. The synthesis zone operates under conditions compatible with the reformer, producing a product with an increased proportion of benzene and toluene while reducing C8 aromatics.
