Latest Patents

William E. Shewbart holds a patent for a method of preparing C4 to C10 alpha-olefins, which emphasizes the production of C6 alpha-olefins. This method utilizes tri-alkyl aluminum compounds, such as Al(C2H5)3 or Al(C4H9)3, in a growth step that incorporates added ethylene at approximately 120°C and under pressures of 500-700 psig. The process involves a contact time of 5-90 minutes, followed by displacement with C2H4 or C4H8 to free the growth alkyl and regenerate the tri-alkyl aluminum compounds. The growth alpha-olefins are then separated, with all C2H4 recycled to the growth and displacement steps, and part or all of the C4H8 recycled to the displacement step.
