Ukuhlengahlengiswa kwemali yinkqubo ebalulekileyo kwi-petroleum ishishini lokucoca, ngokuyintloko kugxilwe ekuphuculeni umgangatho we-petroli. Phakathi kweenkqubo ezahlukeneyo zokuguqula,Ukuphinda uqhubeke ngokutsha kwakhona. Inxalenye ephambili yale nkqubo kukutshintsha kwenkuthazo, edlala indima ebalulekileyo ekuqhubeni ukuphendula kwekhemikhali eyimfuneko ekuguqukeni kwe-naphtha kwi-daphtha ixabisekileyo.
Yintoni iUkutshintsha kweCCR?
Ukutshintsha kwe-CCR yitekhnoloji yokulungisa kwanamhlanje evumela ukuphinda kwenziwe ngokutsha kwenkqubo esetyenziswayo kwinkqubo yokutshintsha. Le ndlela iyahlulahlula i-batch yemveli, apho i-catalyst isuswe ngamanye amaxesha ukuphinda iphinde ivuselelwe. Kwi-CCR eguqukayo, inkathalo ihlala isetoliki, kwaye ukurenta kwenzeka kwiyunithi eyahlukileyo, kuvumela umsebenzi ozinzileyo ngakumbi kunye negalelo eliphezulu. Le nkqubo eqhubekayo ayiphumi nje kuphela isivuno sepetroli ephezulu ye-octane kodwa iphucula ukusebenza kakuhle komsebenzi wokwala.
Indima ye-CatalySts ekuqwalaselweni
I-Catalysts zizinto ezikhawulezayo zokuphendula kwekhemikhali ngaphandle kokuba zichithwe kwinkqubo. Kwimeko yeUkutshintsha kweCCR, I-Catalyst ibalulekile kwizinto ezininzi, kubandakanya nehlelo lokusebenza, i-ISOMEDIZA, kunye ne-hydrocracction. Ezi zinto zasabela ngokuthe ngqo-chain hydrocarbs kwi-hydrocarbons ye-hydrocarbons, eneereyithingi ze-octane ephezulu kwaye inqweneleka kakhulu kwifomuni ye-petroli.
Eyona nto isetyenziswayo isetyenziswa kakhulu kwi-CCR Refys yiplatinams esekwe kwiPlatinals, ihlala ixhaswa kwi-Aluminii. IPlatinam ithandwa ngenxa yomsebenzi wayo obalaseleyo kwaye ukhetha ekukhuthazeni ukuphendula okufunwayo. Ukongeza, ukusetyenziswa kwenkani ye-gatalyst, edibanisa zombini iisayithi zensimbi kunye ne-acid, ivumela ukuguqulwa okusebenzayo kwe-naphthane kwiimveliso eziphezulu. Indawo yensimbi iququzelela ukuchuma, ngelixa ii-asidi ze-acid zikhuthaza ukwakhiwa kwe-isomer kunye ne-hydrocracction.
Yeyiphi eyona nto isetyenziswayo esetyenziswayo kwiReflomer?
Kwi-CCR yokutshintsha, iEyona nto iphambiliisetyenzisiwe ngokwesiqhelo iplatinam-alumina Catalyst. Esi sizathu senzelwe ukumelana neemeko ezinzima zenkqubo yokutshintsha, kubandakanya nobushushu obuphakamileyo kunye noxinzelelo. Icandelo lePlatinam linoxanduva lomsebenzi obalulekileyo, ngelixa iNkxaso ye-Alumna ibonelela ngokuzinza kunye nendawo engaphezulu yendawo yokuphendula.
Ukongeza kwiPlatinam, ezinye izinyithi ezinje nge-rhenium zinokongezwa ukuphucula ukusebenza kwe-catalyst. I-Rhenium inokuphucula ukuxhathisa kwe-catalyst ukuphelisa i-deactivation kwaye yongeza isivuno esipheleleyo se-upelline ye-octane. Ukuqulunqwa kwenkuthazo kunokwahluka ngokuxhomekeka kwiimfuno ezithile zenkqubo yokucoca kunye nenkcazo eyimveliso oyifunayo.
Ukuqukumbela
I-Catalysts eguqula inkathalo, ngakumbi kwimeko ye-CCR yokutshintsha, ibalulekile ekuvelisweni kwe-petroli ekumgangatho ophezulu. Ukukhetha i-Catalyst, ngokwesiqhelo iplatinam-Alumina yeplatina, ichaphazela kakhulu ukusebenza kunye nokusebenza kwenkqubo yokutshintsha. Njengoko imfuno yokucoca icocekile kwaye i-fuels efanelekileyo ngakumbi iyaqhubeka nokunyuka, ukuqhubela phambili itekhnoloji yenkuthazo kuya kudlala indima ebaluleke kakhulu ekubumbeni ikamva lemveliso yepetrol. Ukuqonda intshukumo yezikali kunye nemisebenzi yabo kubalulekile kwiingcali zokuhlaziya okujolise ekwenzeni imisebenzi yabo kwaye ihlangabezane neemfuno zentengiso.
