Oxypro
Oxypro :
(1) A process for making di-isopropyl ether (DOPE) from a propane/propylene stream from FCC. The catalyst system is superior to other acid catalysts such as zeolites because of its greater activity at low temperatures. The Oxypro catalyst functions at below 175ºC, whereas zeolites require temperatures closer to 260ºC. DOPE is used as a gasoline additive. (2) A family of pulp-bleaching processes developed by Air Products and Chemicals. Piloted in 1995 at Pittsfield, MA. Oxypro OR is for processing mixed office waste papers; it uses molecular oxygen, optionally hydrogen peroxide, sodium hydroxide, and a stabilizer
