Ethylene kutsemuka C5 chidimbu cheatmospheric pressure rectification intercepts 45-75â isoprene enriched component as raw material A; ethylene cracking C5 fraction atmospheric pressure rectification intercepts 25-45â isoprene enriched component as raw material B; Ethylene cracking C9 fraction is vacuum yakagadziriswa pasi pe0.08ï½0.095MPa,Petroleum Resin uye chikamu chine boiling point ye140ï½180â chinotorwa seyakagadzirwa C. Zvinhu zvitatu zviri pamusoro apa A, B neC zvinogadzirwa zvinoenderana ne huwandu hwehuwandu hwe1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization raw material D;
Mushure mekubvisa mvura yakataurwa pamusoro pepolymerization raw material D kuburikidza ne4A molecular sieve packing tower, Petroleum Resin selective hydrogenation inoitwa nePd/Al2O3 catalyst kubvisa alkyne, Petroleum Resin uyezve 0.05 kusvika 0.5 wt% yeFriedelCrafts catalyst inowedzerwa, prepolymerized pakamuri tembiricha kwemaawa 0.5 kusvika 1.5, Petroleum Resin uye ipapo calcium hydroxide Iyo catalyst inobviswa kubva musanganiswa nemethanol, uye mushure mekuita distillation, Petroleum Resin iyo polymer raw material chidimbu E ine kuvira kwe25 kusvika 180 ° C inowanikwa. ;Petroleum Resin iyo iri pamusoro pepolymerized raw material E inoiswa prepolymerized mu-high-pressure reaction kettle ine inobvongodza patembiricha ye180°C kusvika 230°C kwemaawa matatu kusvika mashanu. Tora iyo dimerization chigadzirwa F cheCentaolefin uye Styrene kana Methyl Styrene;
Uchishandisa yataurwa pamusoro dimerization chigadzirwa F seyakagadzirwa, Petroleum Resin inosanganiswa neinonyungudutsa inonyungudutsa pachiyero che1: 0.1 kusvika 1.0, Petroleum Resin uye nekuwedzera gaseous boron trifluoride catalyst accounting ye0.1 kusvika 0.5% yehuremu hwese hwese. yemidziyo yekukonzeresa polymerization pa30 kusvika 65 ° C 2 kusvika A yakasviba yero kune brown polymerization mhinduro yakawanikwa mumaawa mashanu. Mushonga wepolymerization wakabviswa catalyst nemusanganiswa we calcium hydroxide uye methanol kuti vawane yakacheneruka yeresin resin solution;Petroleum Resin iri pamusoro resin solution yakaitwa nemagetsi desalination uye kupera mvura mumuviri pa50 kusvika 80° C. Pass active Al2O3 solid bed. pa â;
Iyo C5/C9 petroleum resin solution mushure meiyo pretreatment yanyungudika mu dilution solvent pachiyero che1:1 kusvika ku5, uye inoiswa pasi pe hydrogenation reaction pamberi peiyo modified Pd catalyst kuti iwane hydrogenated diluted resin solution. . ï½295â, reaction hydrogen pressure is 10.0ï½17.0MPa,Petroleum Resin reaction space velocity is 0.125ï½0.333h/1, reaction time is 3ï½8h;Petroleum Resin bvisa solvent uye low Polymer,Petroleum Resin , C5/C9 hydrogenated petroleum resin.
