Title: Innovations of John R Schell in Reactive Distillation Processes
Introduction
John R Schell is a notable inventor based in Austin, TX, who has made significant contributions to the field of chemical engineering. He holds 2 patents that focus on innovative processes for the alkylation of aromatic hydrocarbons. His work is particularly relevant in the context of improving efficiency and selectivity in chemical reactions.
Latest Patents
Schell's latest patents include a "Reactive distillation alkylation process including in situ catalyst regeneration." This unified process couples a unique in situ catalyst regeneration method with continuous reactive distillation under pressure. It is designed for the alkylation of light aromatic hydrocarbons, such as benzene, with C–C olefins using a solid acid alkylation catalyst. The process allows for periodic regeneration of the catalyst, which is achieved through a countercurrent injection of C–C paraffin. This innovative approach significantly reduces the pressures required for catalyst regeneration.
Another notable patent is the "Reactive distillation process for the alkylation of aromatic hydrocarbons." This process also utilizes a reactive distillation configuration under pressure for the alkylation of light aromatic hydrocarbons. The method allows for the continuous injection of olefins below the benzene rectification zone, enhancing the efficiency of the alkylation reaction. The ability to adjust the molar ratio of aromatic hydrocarbon to olefin in the liquid phase is a key feature that increases selectivity to mono-alkylated aromatics.
