Ukuqhekeka kwe-ethylene C5 iqhezu lolungiso loxinzelelo lwe-atmospheric luthintela i-45-75â isoprene icandelo elityetyisiweyo njengezinto ezikrwada A; Ukuqhekeka kwe-ethylene C5 iqhezu lokulungiswa koxinzelelo lwe-atmospheric i-25-45â isoprene icandelo eliphuculweyo njengezinto ezikrwada B; I-Ethylene cracking C9 fraction is vacuum ilungiswa phantsi kwe-0.08ï½0.095MPa,Petroleum Resin kunye neqhezu elinendawo yokubilisa ye-140ï½180â lithathwa njengemathiriyeli ekrwada C. Ezi zixhobo zintathu zingentla zilungiswe ngu-A, B no-C zilungiswe ngokwe umlinganiselo wobunzima 1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization imathiriyeli ekrwada D;
Emva kokumisa amanzi e-polymerization echazwe ngasentla nge-4A ye-molecular sieve packing tower, i-Petroleum Resin ekhethiweyo i-hydrogenation yenziwa nge-Pd/Al2O3 catalyst yokususa i-alkyne, i-Petroleum Resin emva koko i-0.05 ukuya kwi-0.5 wt% ye-FriedelCrafts catalyst yongezwa, I-prepolymerized kwiqondo lobushushu begumbi kwi-0.5 ukuya kwiiyure ze-1.5, i-petroleum Resin kunye ne-calcium hydroxide I-catalyst iyasuswa kumxube kunye ne-methanol, kwaye emva kokuxutywa kwe-distillation, i-petroleum Resin iqhezu le-polymer ekrwada E enendawo yokubilisa engama-25 ukuya kwi-180 ° C ifunyenwe. ;I-petroleum Resin le imathiriyeli epholima ngentla apha ekrwada i-E ifakwe kwi-prepolymerized kwi-ketile yokusabela koxinzelelo oluphezulu ngokuvuselela kubushushu obuyi-180°C ukuya kuma-230°C kangangeeyure ezi-3 ukuya kwezi-5. Fumana imveliso ye-dimerization F ye-Centaolefin kunye ne-Styrene okanye i-Methyl Styrene;
Usebenzisa imveliso yedimerization ekhankanywe ngasentla F njengesixhobo ekrwada, i-petroleum Resin ixutywa nesinyibilikisi sokunyibilikisa kumlinganiselo wobunzima obuphakathi kwe-1:0.1 ukuya kwi-1.0, i-petroleum Resin kunye nokongeza i-gaseous boron trifluoride catalyst accounting ye-0.1 ukuya kwi-0.5% yobunzima bubonke bubonke. wemathiriyeli catalyze polymerization kwi 30 ukuba 65 ° C 2 ukuya A mnyama tyheli ukuya kumdaka isisombululo polymerization yafunyanwa kwiiyure ezi-5. Isisombululo se-polymerization sahluthwa i-catalyst kunye nomxube we-calcium hydroxide kunye ne-methanol ukufumana isisombululo se-resin ephuzi; e â;
Isisombululo se-petroleum ye-C5 / C9 ye-petroleum resin emva kokuba i-pretreatment ingentla ichithwa kwi-solvent ye-dilution kumlinganiselo omkhulu we-1: 1 ukuya ku-5, kwaye ixhomekeke kwimpendulo ye-hydrogenation phambi kwe-catalyst ye-Pd eguquliweyo ukuze ufumane isisombululo se-hydrogenated diluted resin. . ï½295â, i-reaction hydrogen pressure yi-10.0ï½17.0MPa, i-petroleum Resin reaction space velocity yi-0.125ï 0.333h/1, ixesha lokusabela yi-3ï½8h; I-Petroleum Resin susa isinyibilikisi kunye nePolymer ephantsi, i-Petroleum Resin , C5 / C9 i-hydrogenated petroleum resin.
