| Abstract: | This paper introduced the commercial application of VAH type gas-phase aldehyde hydrogenation catalyst.VAH type catalyst was applied at the 40 kt/a propyl alcohol unit of Nuoao chemical company.Controlling the process of catalyst loading to avoid catalyst damage and ensure the tube pressure difference were between 35～50 kPa;Strictly controlling the hydrogen concentration in the nitrogen during the catalyst reduction process,to ensure a complete catalyst reduction reaction and temperature rise couldn’t happen.The application results showed that product qualities completely met the requirements,VAH type catalyst had higher hydrogenation activity and better selectivity,thus commercial application of VAH type gas-phase aldehyde hydrogenation catalyst was successfully realized at the 40 kt/a propyl alcohol unit. |
