Latest Patents

Richard's latest patents include:

1. **Reactive distillation alkylation process including in situ catalyst regeneration**

This patent represents a unified process that combines a unique in situ catalyst regeneration method with continuous reactive distillation under pressure for the alkylation of light aromatic hydrocarbons, such as benzene, with C-C olefins. The process utilizes a solid acid alkylation catalyst supported in the reflux zone of a distillation column. Noteworthy aspects involve periodic regeneration of the catalyst achieved with a countercurrent injection of a C-C paraffin, allowing for lower pressures to be maintained during the procedure.

2. **Reactive distillation process for the alkylation of aromatic hydrocarbons**

This innovative process involves continuous reactive distillation under pressure for the alkylation of light aromatic hydrocarbons like benzene and cumene. The process features a configuration whereby olefins are injected below the benzene rectification zone, allowing precise adjustments to the molar ratio of aromatic hydrocarbons to olefins in the liquid phase. This adjustment enhances selectivity towards mono-alkylated aromatics and stabilizes catalyst lifetime.
