Latest Patents

Lewis’s inventions focus on two significant aspects of alkylation processes. His first patent, titled "Sulfuric Acid Catalyzed Alkylation Process," describes a method for alkylating isoparaffin hydrocarbons with olefin hydrocarbons in the presence of a sulfuric acid alkylation catalyst. This innovative process involves treating hydrocarbon effluent from an alkylation reaction zone in the liquid phase with bauxite or a similar adsorbent to remove acid alkyl sulfates, neutral alkyl sulfate, and other corrosive species. The treated effluent is then flashed at reduced pressure, allowing for the cooling of the alkylation reaction mixture and facilitating the recovery of isoparaffin recycle and alkylated hydrocarbon products.

His second patent, "Converting Reactive Impurities in Isobutane Charge Stream with Catalyst," details an alkylation process where isoparaffin hydrocarbons are alkylated with olefin hydrocarbons using an alkylation catalyst composed of sulfuric acid. This process includes a pretreatment step that removes contaminants reactive with sulfuric acid under alkylation conditions, further enhancing the quality of the alkylated hydrocarbons produced for use in motor fuels.
