Abstract
A method for starting up a fixed bed propylene hydration reactor containing shape selective metallosilicate catalyst particles for the production of isopropanol and/or diisopropyl ether is disclosed comprising the following sequential steps: contacting a feedstream comprising propane with catalyst particles in a hydration reactor; then introducing a feedstream comprising isopropanol into the reactor to displace propane. Next, a feedstream comprising propylene is introduced into the reactor under etherification conditions. Finally, a feedstream is introduced in the reactor comprising water under etherification and hydration reaction conditions whereby diisopropyl ether and isopropanol are produced.
