The BDO production process is that acetylene and formaldehyde pass through the catalyst (Raney nickel catalyst) slurry layer in countercurrent, and react at 93°C, 0.1 MPa with the catalyst.
After the generated BYD is separated from the catalyst by the built-in candle filter (adopted the para-aramid / Kevlar filter fabric bag), the catalyst remains in the reactor. And the para-aramid candle filter bag/ Kevlar candle filter bags from Zonel Filtech will be equipped with the relevant candle filters to help finish this processing under the high temperature and high pressure circumstance.
The Reney Nickel catalyst will be collected by filter bags, then the filtered crude BYD will enters the BYD purification unit to remove methanol and formaldehyde, and the purified BYD solution enters the hydrogenation section. BYD hydrogenation is carried out in two fixed-bed reactors connected in series, and 99% of the hydrogenation reaction is completed in the first reactor.
