1.Sulfony 13 oxybicyclo[9.3.0]tetradec 3,8 diyne is the precursor of the bicyclic enediyne which has been synthesized from cis 1,2,3,6 tetrahydropathalican hydride by 8 step reactions. We got the goal compound by reduction of anhydride, ozonolysis of 8 oxabicyclo[4.3.0]non 3 ene, Witting reaction with PPh 3/CBr 4, formation of alkyne and esterification, reduction of the ester, formation of the mesylate, cyclization with sodium sulfide nonhydrate.
5.So even if all CFC production stopped immediately, the threat of ozone depletion would continue for more than a century.
6.The pilot-scale experiment was carried out by ozone-combined processes composed of pre-ozonation-conventional treatment-O3-BAC advanced treatment. The removal rates were 62. 3% for CODMn ,91. 8% for UV254,63. 7% for DOC and 27% for AOC.
7.The ozonation increased the concentration of BDOC in 0.12～0.54(mg/L) with ozone dose of 2～8(mg/L) and BAC filtration decreased concentration of BDOC to 0.23～0.31(mg/L).
9.Activated carbon was selected as the best bio-filter in the bio-filter system, nitrification sphaericus as the best microbe which could reduce ammonia nitrogen content of the oil refinery sewage from 40mg/l to below 4mg/l at 30℃ in a duration time of 0.83h to meet the water quality demand of circular cooling water.
10.The refinery post -biodegradable waste water was disposed with FCC stable catalyst used as absorption agent and catalyst.
