Latest Patents

One of her latest patents focuses on the catalytic cracking of ethers to produce 1-olefins. This innovative process involves converting ethers into α-olefins by passing them over a modified alumina catalyst. The catalyst is created by treating gamma-alumina with a rare earth metal oxide, such as lanthanum oxide (LaO). This modified aluminum catalyst demonstrates high selectivity and conversion rates, particularly in converting 1-methoxyoctane into 1-octene. Another significant patent involves cracking 1-ethers over unmodified γ-alumina. This process operates at temperatures ranging from 250 to 350°C and pressures between 10 to 200 kPa, achieving high conversions and good selectivity to produce the corresponding 1-alkene. This method is especially effective for producing 1-octene from 1-methoxyoctane.
